935,000,000,000 YBN | 4) There is a pattern in the universe. Light particles move from where there is less space to where there is more space. As an empty space becomes filled, light particles form gas clouds called nebuli, and then galaxies of stars. Living objects grow around stars and pull stars together to form globular clusters and then form a globular (also called "elliptical") galaxy. Living objects need matter to stop their decay. Globular galaxies have a regular input and output of light particles. When a volume of space becomes very dense, more light particles exit than enter the space. Light particles that exit to more empty spaces form new nebulae and galaxies and so this cycle continues. Stars at our scale may be light particles at a much larger scale, just as light particles at our scale may be stars at a much smaller scale. This system may go on infinitely in both larger and smaller scale.2 FOOTNOTES 1. ^ Ted Huntington. 2. ^ Ted Huntington. |

Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard's Loop - a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. But the obscuring dust of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away. At that distance, this 1 degree wide field of view would span less than 10 light-years. PD source: http://apod.nasa.gov/apod/image/ 0705/ldn1622_carboni.jpg | |

Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers. Still, this beautiful digital image shows off the Iris Nebula's range of colors and symmetries in impressive detail. Within the Iris, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the dusty clouds glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs. As shown here, the bright blue portion of the Iris Nebula is about six light-years across.

M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the constellation Sagittarius. The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars, which lie outside the picture to the upper left. The glow of these patterns accentuates the three-dimensional structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this photograph. The intense heat and pressure cause some material to stream away from those surfaces, creating the glowing veil of even hotter greenish gas that masks background structures. The pressure on the tips of the waves may trigger new star formation within them. The image, roughly 3 light-years across, was taken May 29-30, 1999, with the Wide Field Planetary Camera 2. The colors in the image represent various gases. Red represents sulfur; green, hydrogen; and blue, oxygen.

[1] RNA is a versatile molecule. In its most familiar role, RNA acts as an intermediary, carrying genetic information from the DNA to the machinery of protein synthesis. RNA also plays more active roles, performing many of the catalytic and recognition functions normally reserved for proteins. In fact, most of the RNA in cells is found in ribosomes--our protein-synthesizing machines--and the transfer RNA molecules used to add each new amino acid to growing proteins. In addition, countless small RNA molecules are involved in regulating, processing and disposing of the constant traffic of messenger RNA. The enzyme RNA polymerase carries the weighty responsibility of creating all of these different RNA molecules. The RNA Factory RNA polymerase is a huge factory with many moving parts. The one shown here, from PDB entry 1i6h, is from yeast cells. It is composed of a dozen different proteins. Together, they form a machine that surrounds DNA strands, unwinds them, and builds an RNA strand based on the information held inside the DNA. Once the enzyme gets started, RNA polymerase marches confidently along the DNA copying RNA strands thousands of nucleotides long. Accuracy As you might expect, RNA polymerase needs to be accurate in its copying of genetic information. To improve its accuracy, it performs a simple proofreading step as it builds an RNA strand. The active site is designed to be able to remove nucleotides as well as add them to the growing strand. The enzyme tends to hover around mismatched nucleotides longer than properly added ones, giving the enzyme time to remove them. This process is somewhat wasteful, since proper nucleotides are also occasionally removed, but this is a small price to pay for creating better RNA transcripts. Overall, RNA polymerase makes an error about once in 10,000 nucleotides added, or about once per RNA strand created. Poisoning Polymerase Since RNA polymerase is absolutely essential for the life of the cell, it is a sensitive target for poisons and toxins. The most powerful of these poisons is alpha-amanitin, a small circular peptide created by the death cap mushroom. Eating even one of these mushrooms will lead to coma and death in a manner of days, as the poison attacks RNA polymerase throughout the body. Surprisingly, it binds on the back side of RNA polymerase, away from the active site and away from the binding site for the DNA and RNA. It does not physically block the active site, like most inhibitors, but instead jams the mechanism of the enzyme. RNA polymerase is a highly mobile enzyme, that flexes and changes shape as it performs the sequential steps of binding to DNA, unwinding it, and then building the RNA strand. As seen in PDB entry 1k83, the poison binds between two subunits of the protein, gluing them together and blocking these essential motions.

PD source: http://upload.wikimedia.org/wiki pedia/commons/d/dc/Urzwerg.jpg [2] Figure 1) Changing views of the tree and timescale of life. a) An early-1990s view, with the tree determined mostly from ribosomal RNA (rRNA) sequence analysis. This tree emphasizes vertical (as opposed to horizontal) evolution and the close relationship between eukaryotes and the Archaebacteria. The deep branching (>3.5 Giga (109) years ago, Gya) of CYANOBACTERIA (Cy) and other Eubacteria (purple), the shallow branching (approx1 Gya) of plants (Pl), animals (An) and fungi (Fu), and the early origin of mitochondria (Mi), were based on interpretations of the geochemical and fossil record7, 8. Some deeply branching amitochondriate (Am) species were believed to have arisen before the origin of mitochondria44. Major symbiotic events (black dots) were introduced to explain the origin of eukaryotic organelles42, but were not assumed to be associated with large transfers of genes to the host nucleus. They were: Eu, joining of an archaebacterium host with a eubacterium (presumably a SPIROCHAETE) to produce an amitochondriate eukaryote; Mi, joining of a eukaryote host with an alpha-proteobacterium (Ap) symbiont, leading to the origin of mitochondria, and plastids (Ps), joining of a eukaryote host with a cyanobacterium symbiont, forming the origin of plastids on the plant lineage and possibly on other lineages. b) The present view, based on extensive genomic analysis. Eukaryotes are no longer considered to be close relatives of Archaebacteria, but are genomic hybrids of Archaebacteria and Eubacteria, owing to the transfer of large numbers of genes from the symbiont genome to the nucleus of the host (indicated by coloured arrows). Other new features, largely derived from molecular-clock studies16, 39 (Box 1), include a relatively recent origin of Cyanobacteria (approx2.6 Gya) and mitochondria (approx1.8 Gya), an early origin (approx1.5 Gya) of plants, animals and fungi, and a close relationship between animals and fungi. Coloured dashed lines indicate controversial aspects of the present view: the existence of a premitochondrial symbiotic event and of living amitochondriate eukaryotes, ancestors of which never had mitochondria. c) The times of divergence of selected model organisms from humans, based on molecular clocks. For the prokaryotes (red), because of different possible origins through symbiotic events, divergence times depend on the gene of interest. source: http://www.nature.com/nrg/journa l/v3/n11/full/nrg929_fs.html | |

[1] Evolutionary relationships of model organisms and bacteria that show unusual reproductive strategies. This phylogenetic tree (a) illustrates the diversity of organisms that use the alternative reproductive strategies shown in (b). Bold type indicates complete or ongoing genome projects. Intracellular offspring are produced by several low-GC Gram-positive bacteria such as Metabacterium polyspora, Epulopiscium spp. and the segmented filamentous bacteria (SFB). Budding and multiple fission are found in the proteobacterial genera Hyphomonas and Bdellovibrio, respectively. In the case of the Cyanobacteria, Stanieria produces baeocytes and Chamaesiphon produces offspring by budding. Actinoplanes produce dispersible offspring by multiple fission of filaments within the sporangium. source: http://www.nature.com/nrmicro/jo urnal/v3/n3/full/nrmicro1096_fs.html (Nature Reviews Microbiology 3 [2] Electron micrograph of a Pirellula bacterium from giant tiger prawn tissue (Penaeus monodon).

[1] Listeria monocytogenes is a Gram-positive bacterium, in the division Firmicutes, named for Joseph Lister. It is motile by means of flagella. Some studies suggest that 1 to 10% of humans may carry L. monocytogenes in their intestines. Researchers have found L. monocytogenes in at least 37 mammalian species, both domesticated and feral, as well as in at least 17 species of birds and possibly in some species of fish and shellfish. Laboratories can isolate L. monocytogenes from soil, silage, and other environmental sources. L. monocytogenes is quite hardy and resists the deleterious effects of freezing, drying, and heat remarkably well for a bacterium that does not form spores. Most L. monocytogenes are pathogenic to some degree. source: http://en.wikipedia.org/wiki/Ima ge:Listeria.jpg [2] These are bacteria (about 0.3 µm in diameter) that do not have outer walls, only cytoplasmic membranes. However, they do have cytoskeletal elements that give them a distinct non-spherical shape. They look like schmoos that are pulled along by their heads. How they are able to glide is a mystery. source: http://webmac.rowland.org/labs/b acteria/projects_glide.html | |

[1] Endocytosis and Exocytosis: For example, this electron micrograph is showing the process of exocytosis . The process begins by fusion of the membranes at the peripheral pole of the granule. Then an opening is created which widens to look like an omicron figure. This opening allows the granular material to be released. The membrane is now part of the plasma membrane and any proteins carried with it can be incorporated into the plasma membrane. Note that there is no coating on the membrane. This figure was taken from Alberts et al, Molecular Biology of the Cell, Garland Publishing Third Edition, 1994 In contrast, this micrograph shows a figure which looks something like an omicron, however, this view is showing receptor mediated endocytosis of virus particles. In both cases, the membrane is coated with clathrin and these represent classical receptor mediated endocytosis profiles. Most ligands cannot be visualized by themselves, like a virus particle. Therefore, the cytochemist must attach label to the ligand. Alternatively, the cytochemist could immunocytochemically detect the receptor with antibodies that recognize the extracellular domain. This figure was taken from Endocytosis, Edited by Ira Pastan and Mark C. Willingham, Plenum Press, N.Y., 1985 COPYRIGHTED source: http://www.cytochemistry.net/cel l-biology/end7.jpg [2] Pinocytosis In the process of pinocytosis the plasma membrane froms an invagination. What ever substance is found within the area of invagination is brought into the cell. In general this material will be dissolved in water and thus this process is also refered to as ''cellular drinking'' to indicate that liquids and material dissolved in liquids are ingested by the cell. This is opposed to the ingestion of large particulate material like bacteria or other cells or cell debris. UNKNOWN source: http://academic.brooklyn.cuny.ed u/biology/bio4fv/page/endocytb.htm | |

[1] Cilia and flagella are projections from the cell. They are made up of microtubules , as shown in this cartoon and are covered by an extension of the plasma membrane. They are motile and designed either to move the cell itself or to move substances over or around the cell. The primary purpose of cilia in mammalian cells is to move fluid, mucous, or cells over their surface. Cilia and flagella have the same internal structure. The major difference is in their length. This figure shows a cross section of a cilium next to a longitudinal section. Below, we will see how the microtubules are organized in the core (shown in the cartoon in this figure). Also shown is the centriole or basal body that organizes the formation and direction of the cilia. COPYRIGHTED source: Description Transmission electron microscope image, showing an example of green algae (Chlorophyta). Chlamydomanas reinhardtii is a unicellular flagellate used as a model system in molecular genetics work and flagellar motility studies. This image is a longitudinal section through the flagella area. In the cell apex is the basal body that is the anchoring site for a flagella. Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets(see structure at bottom center of image). The two inner microtubules of each triplet in a basal body become the two outer doublets in the flagella. This image also shows the transition region, with its fibers of the stellate structure. The top of the image shows the flagella passing through the cell wall. Date 20 September 2007 Source Source and public domain notice at http://remf.dartmouth.edu/imagesindex.ht ml Author Dartmouth Electron Microscope Facility, Dartmouth College PD [2] This figure shows an electron micrograph of a cross section of a cilium. Note that you can see the dynein arms and the nexin links. The dynein arms have ATPase activity. In the presence of ATP, they can move from one tubulin to another. They enable the tubules to slide along one another so the cilium can bend. The dynein bridges are regulated so that sliding leads to synchronized bending. Because of the nexin and radial spokes, the doublets are held in place so sliding is limited lengthwise. If nexin and the radial spokes are subjected to enzyme digestion, and exposed to ATP, the doublets will continue to slide and telescope up to 9X their length.

If DNA is pictured as a twisted ladder, its sides, made of sugar and phosphate molecules, are connected by (c) rungs made of chemicals called bases. DNA has four bases—adenine, thymine, guanine, and cytosine—that form interlocking pairs. The order of the bases along the length of the ladder is the DNA sequence.

The sediments are essentially rust-free. After the late Proterozoic, sedimentary deposits often have reddish colors and are called red beds due to the presence of iron-oxide coatings between sand grains. From the later Proterozoic onward, enough free oxygen has been available to oxidize iron in sediments. A sandstone butte outside of Sedona, Arizona. Public domain image by Jon Sullivan.

[1] Figure 1: Figure 1. Eukaryote phylogeny integrating ultrastructure, sequence trees, gene fusions and molecular cladistic markers. The unikont topology is established, but the branching order of the six bikont groups remains uncertain. The single enslavement [12] of a red alga (R) to create chromalveolates is supported by a plastid glyceraldehyde phosphate dehydrogenase (GAPDH) replacement [13]. Whether there was a single enslavement of a green alga (G) to form cabozoa or two separate enslavements (asterisks) to form Cercozoa and Excavata is uncertain [12], as is the position of Heliozoa [14]. Polyubiquitin [15] and EF-1α[16] insertions strongly support the clades core Rhizaria and opisthokonts. The inset shows the BamHI restriction fragment from H. cantabrigiensis that was sequenced and analysed in this study, spanning the DHFR and the amino terminus of the TS gene (red, introns are green). The length of the noncoding regions upstream and downstream of the DHFR gene from one of the clones is indicated.

[1] A timescale of eukaryote evolution. The times for each node are taken from the summary times in Table 1, except for nodes 1 (310 Ma), 2 (360 Ma), 3 (450 Ma), and 4 (520 Ma), which are from the fossil record [25]; nodes 8 (1450 Ma) and 16 (1587 Ma) are phylogenetically constrained and are the midpoints between adjacent nodes. Nodes 12–14 were similar in time and therefore shown as a multifurcation at 1000 Ma; likewise, nodes 21–22 are shown as a multifurcation at 1967 Ma. The star indicates the occurrence of red algae in the fossil record at 1200 Ma, the oldest taxonomically identifiable eukaryote [12]. Hedges et al.

[1] Volvoxcell differentiation. The pathways leading to germ cells or somatic cells are controlled by genes that cause cells to follow one or the other fate. Mutations can prevent the formation of one of these lineages. http://www.devbio.com/chap02/link0204.sh tml Although all the volvocaceans, like their unicellular relative Chlamydomonas, reproduce predominantly by asexual means, they are also capable of sexual reproduction, which involves the production and fusion of haploid gametes. In many species of Chlamydomonas, including the one illustrated in Figure 2.10, sexual reproduction is isogamous (“the same gametes”), since the haploid gametes that meet are similar in size, structure, and motility. However, in other species of Chlamydomonas—as well as many species of colonial volvocaceans—swimming gametes of very different sizes are produced by the different mating types. This pattern is called heterogamy (“different gametes”). But the larger volvocaceans have evolved a specialized form of heterogamy, called oogamy, which involves the production of large, relatively immotile eggs by one mating type and small, motile sperm by the other (see Sidelights and Speculations) UNKNOWN source: http://www.ncbi.nlm.nih.gov/book s/NBK10031/bin/ch2f12.jpg [2] Description English: Four Different Species of Volvocales Algae.

[1] Fig. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae—a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red).

The neon water is brimming with dinoflagellates, single-celled plankton with tails that slosh around together in vast numbers. These creatures have been highlighting Earth’s coastlines for 1.2 billion years, and for the past few millennia, they’ve puzzled humans, who used to attribute the glow of some ocean water to magic or the gods.Dinoflagellates still puzzle us; we know how they glow, but not why. They might have evolved bioluminescence as a way of frightening predators, or to reveal those predators’ locations by flashing when touched. Alternatively, their bioluminescence may just be a fancy way of ridding themselves of oxygen radicals (because the chemical reaction requires oxygen). Whatever the answer, they certainly make for a nice holiday in the Bahamas. UNKNOWN source: http://www.lifeslittlemysteries. com/images/i/1651/original/dinoflagellat e.jpg | |

The cells are cylindrical with a rounded anterior and tapered posterior. The chloroplasts are well-developed, bright green, and sometimes have pyrenoids. They are often discoidal in shape but can also be ovate, lobate, elongate, U-shaped, or ribbon-shaped. Some researchers use the structure and position of the chloroplasts to divide the group into three subgenera. Even though they are able to photosynthesize, Euglena cells also have a phagotrophic ingestion apparatus. Euglena has one long, protruding flagellum and a shorter flagellum that is not usually visible. The euglenoids can glide and swim using their flagella, or can ooze along a substrate with an undulating, shape-changing, contraction motion called metaboly. The cytoplasm of Euglena and other euglenoids contains many paramylon starch storage granules. The euglenoid cells are covered by a pellicle composed of ribbonlike, woven strips of proteinaceous material that cover the cell in a helical arrangement from apex to posterior. Freshwater euglenoids have a contractile vacuole. Euglenoids sense light using a red pigmented eyespot or stigma and the paraflagellar body located at the base of the emergent flagella.

Note the parasite forms branching hyphae-like structures. Ichthyophonus hoferi has caused massive mortalities in herring in the Atlantic ocean, and has recently been reported to cause disease in wild Pacific herring from Washington through Alaska. COPYRIGHTED EDU source: http://oregonstate.edu/dept/salm on/projects/images/16Ichthyophonus.jpg [2] Microscopic appearence of the organism is dependent on its stage of development. The stages include (1) spore at ''resting'' stage, (2) germinating spore, (3) hyphal stage. It is believed that there are two forms of Ichthyophonus, both belonging to one genus. One of them is known as the ''salmon'' form, occuring in freshwater and cold-preferring sea fishes: this form is characterized by its ability to produce long tubulose germ hyphae. The other is called the ''aquarium fish'' form, typical of the tropical freshwater fishes. This form is completely devoid of hyphae. Developmental cycle of Ichthyophonus hoferi: 1-5 - development of ''daughter'' spores, 7-11 - development of resting spore from the ''daughter'' spore, 12-19 - development of resting spore by fragmentation.

The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

[1] Paramecium protozoan, SEM C001/0068 Rights Managed Credit: STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY Caption: Paramecium protozoan, coloured scanning electron micrograph (SEM). Paramecia are a group of unicellular ciliate protozoa. They inhabit fresh water, and feed mainly on bacteria and smaller protozoa. Paramecia range from about 50 to 350 micrometres in length, depending on species. Simple cilia, which cover the body, are moved in a synchronous motion to allow the cell to move.

PD [1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

Record information: Salpingoeca (sal-ping-go-eek-a), a collar flagellate (choanoflagellate) - all of which have a single anterior flagellum surrounded by a collar of very fine pseudopodia (in cross-section the collar seems like two arms, one on either side of the flagellum). The flagellum beats drawing water through the collar and bacteria and other small particles are trapped and then ingested. Believed to be the source group of the sponges and the metazoa. Salpingoeca has an organic lorica. Phase contrast.

[1] A general view of the life in the time frame from about 605 to 542 million years ago (the Vendian), is found at this New Zealand site which concentrates on the Ediacaran epoch; it mentions Australian and other geographic localities where the assemblages have been found. The fossil life is represented entirely by creatures with soft parts only. It is suggested that these may be ancestral to later phylla observed at the beginning of the Paleozoic.

These groups differ in several characteristics of early development; In deuterostomes blastula devisions is called ''radial cleavage'' because it occurs parallel or perpendicular to the major polar axis. In protostomes the cleavage is called ''spirale'' because division planes are oriented obliquely to the polar major axis. During gastrulation, protostomes embryos' mouth was given first by the blastopore while the anus was formed later and vis versa for the deuterostomes. As examples : Squids are protostomes.

Individual zooids can crawl about freely within the colony, but are connected to one another by thin “cables,” quickly retracting if disturbed. What makes the Pterobranchs even stranger than corals is that these slimy, slithering weirdos are “hemichordates,” closer to us vertebrates than to invertebrates like worms and jellyfish.

[1] FIG. 2. The tree of life based on molecular, ultrastructural and palaeontological evidence. Contrary to widespread assumptions, the root is among the eubacteria, probably within the double-enveloped Negibacteria, not between eubacteria and archaebacteria (Cavalier-Smith, 2002b); it may lie between Eobacteria and other Negibacteria (Cavalier-Smith, 2002b). The position of the eukaryotic root has been nearly as controversial, but is less hard to establish: it probably lies between unikonts and bikonts (Lang et al., 2002; Stechmann and Cavalier-Smith, 2002, 2003). For clarity the basal eukaryotic kingdom Protozoa is not labelled; it comprises four major groups (alveolates, cabozoa, Amoebozoa and Choanozoa) plus the small bikont phylum Apusozoa of unclear precise position; whether Heliozoa are protozoa as shown or chromists is uncertain (Cavalier-Smith, 2003b). Symbiogenetic cell enslavement occurred four or five times: in the origin of mitochondria and chloroplasts from different negibacteria, of chromalveolates by the enslaving of a red alga (Cavalier-Smith, 1999, 2003; Harper and Keeling, 2003) and in the origin of the green plastids of euglenoid (excavate) and chlorarachnean (cercozoan) algae-a green algal cell was enslaved either by the ancestral cabozoan (arrow) or (less likely) twice independently within excavates and Cercozoa (asterisks) (Cavalier-Smith, 2003a). The upper thumbnail sketch shows membrane topology in the chimaeric cryptophytes (class Cryptophyceae of the phylum Cryptista); in the ancestral chromist the former food vacuole membrane fused with the rough endoplasmic reticulum placing the enslaved cell within its lumen (red) to yield the complex membrane topology shown. The large host nucleus and the tiny nucleomorph are shown in blue, chloroplast green and mitochondrion purple. In chlorarachneans (class Chlorarachnea of phylum Cercozoa) the former food vacuole membrane remained topologically distinct from the ER to become an epiplastid membrane and so did not acquire ribosomes on its surface, but their membrane topology is otherwise similar to the cryptophytes. The other sketches portray the four major kinds of cell in the living world and their membrane topology. The upper ones show the contrasting ancestral microtubular cytoskeleton (ciliary roots, in red) of unikonts (a cone of single microtubules attaching the single centriole to the nucleus, blue) and bikonts (two bands of microtubules attached to the posterior centriole and an anterior fan of microtubules attached to the anterior centriole). The lower ones show the single plasma membrane of unibacteria (posibacteria plus archaebacteria), which were ancestral to eukaryotes and the double envelope of negibacteria, which were ancestral to mitochondria and chloroplasts (which retained the outer membrane, red). source: http://aob.oxfordjournals.org/cg i/content/full/95/1/147/FIG2 [2] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

Chronogram showing estimates of phylogenetic relationships and divergence times among the major groups of extant land plants. The estimate of relationships is synthesized from the following papers in this issue: Burleigh and Mathews (2004) , Pryer et al. (2004) , Shaw and Renzaglia (2004) , and Soltis and Soltis (2004) . Divergence time estimates are mostly based on analyses of molecular data with fossil constraints (Wikström et al., 2001 ; Pryer et al., 2004 ) and are augmented by fossil evidence (Kenrick and Crane, 1997 ; Wellman et al., 2003 ). Estimates of the number of species in each group are from Judd et al. (2002) and W. S. Judd (personal communication). Groups covered by a particular article in this special issue are circled and connected to the names of the article's authors. ''Other conifers'' refers to the clade consisting of all conifers except for Pinaceae (see Burleigh and Mathews, 2004 ). ''Lepto. ferns'' refers to leptosporangiate ferns fig 2 from: Jeffrey D.

[1] English: A female subimago of March Brown (Rhithrogena germanica) of family Heptageniidae. Mayflies are insects which belong to the Order Ephemeroptera (from the Greek ephemeros, short-lived and pteron, wing, referring to the short life span of adults). They have been placed into an ancient group of insects termed the Paleoptera, which also contains the dragonflies and damselflies. They are aquatic insects whose immature stage (called naiad or, colloquially, nymph) usually lasts one year in fresh water.

[1] Yes, it's time for the Palaeozoic scenes of Life before Man. Or some of them, anyway - if you really want to see a load of trilobites, you're probably Richard Fortey, and I will ignore any comments that claim otherwise. (Also, I can't include everything - otherwise we'd have to rename this blog Love in the Time of Burian, which sounds a bit rubbish.) My bias is most definitely towards vertebrates and, in particular, tetrapods, and the below scene - featuring Ichthyostega - marks their first appearance in the book. This painting is perhaps unique in this book as it combines the elements of the animal-free landscapes with, well, some animals. Burian's skill is in making this scene, filled as it is with flora so utterly different to what we are accustomed to seeing today, look as if he just took a casual stroll out into the country to paint it.

Divergence time estimates are mostly based on analyses of molecular data with fossil constraints (Wikström et al., 2001 ; Pryer et al., 2004 ) and are augmented by fossil evidence (Kenrick and Crane, 1997 ; Wellman et al., 2003 ).

The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria.

Organisms are divided into three main groups distinguished by mitochondrial cristal shape (either discoidal, flattened or tubular). Unbroken lines indicate phylogenetic relationships that are firmly supported by available data; broken lines indicate uncertainties in phylogenetic placement, resolution of which will require additional data. Color coding of organismal genus names indicates mitochondrial genomes that have been completely (Table 1), almost completely (Jakoba, Naegleria and Thraustochytrium) or partially (*) sequenced by the OGMP (red), the FMGP (black) or other groups (green).

[1] 260 Ma Late Permian UNKNOWN source: http://jan.ucc.nau.edu/~rcb7/260 _Permian_2globes.jpg [2] In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root ''to build.'' Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving relative to one another as they ride atop hotter, more mobile material. Before the advent of plate tectonics, however, some people already believed that the present-day continents were the fragmented pieces of preexisting larger landmasses (''supercontinents''). The diagrams below show the break-up of the supercontinent Pangaea (meaning ''all lands'' in Greek), which figured prominently in the theory of continental drift -- the forerunner to the theory of plate tectonics.

[1] Fig. 1. A consensus phylogeny of eukaryotes. The vast majority of characterized eukaryotes, with the notable exception of major subgroups of amoebae, can now be assigned to one of eight major groups. Opisthokonts (basal flagellum) have a single basal flagellum on reproductive cells and flat mitochondrial cristae (most eukaryotes have tubular ones). Eukaryotic photosynthesis originated in Plants; theirs are the only plastids with just two outer membranes. Heterokonts (different flagellae) have a unique flagellum decorated with hollow tripartite hairs (stramenopiles) and, usually, a second plain one. Cercozoans are amoebae with filose pseudopodia, often living with in tests (hard outer shells), some very elaborate (foraminiferans). Amoebozoa are mostly naked amoebae (lacking tests), often with lobose pseudopodia for at least part of their life cycle. Alveolates have systems of cortical alveoli directly beneath their plasma membranes. Discicristates have discoid mitochondrial cristae and, in some cases, a deep (excavated) ventral feeding groove. Amitochondrial excavates lack substantial molecular phylogenetic support, but most have an excavated ventral feeding groove, and all lack mitochondria. The tree shown is based on a consensus of molecular (1-4) and ultrastructural (16, 17) data and includes a rough indication of new ciPCR ''taxa'' (broken black lines) (7-11).

[1] 200 Ma Early Jurassic UNKNOWN source: http://jan.ucc.nau.edu/~rcb7/200 _Jurassic_2globes.jpg [2] In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root ''to build.'' Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more large and small plates that are moving relative to one another as they ride atop hotter, more mobile material. Before the advent of plate tectonics, however, some people already believed that the present-day continents were the fragmented pieces of preexisting larger landmasses (''supercontinents''). The diagrams below show the break-up of the supercontinent Pangaea (meaning ''all lands'' in Greek), which figured prominently in the theory of continental drift -- the forerunner to the theory of plate tectonics.
