BioNumbers - The Database of Useful Biological Numbers Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

above Yes, We Should Clone Neanderthals | discussion | ethics 30,000 years ago a Neanderthal woman died in what would become Croatia’s Vindija cave. Five years ago, 454 Life Sciences and the Max Planck Institute started working together on the tedious and time-consuming task of piecing her fossilized DNA back together. Just over a month ago, they succeeded and, in the process, revealed that most of us are between 1% and 4% Neanderthal. Knowing where Neanderthals fit, however, also creates a problem. The problem is, of course, that we don’t have a cloned Neanderthal. The argument may seem absurd and offensive at first. As the bioethicist Bernard Rollin points out in the Archaeology piece, there’s more to worry about than the law. Not so. Unlike examples found in science fiction, be it Mary Shelley’s Frankenstein or the more recent sci-horror flick Splice, it’s not as if our only options are to send the neo-Neanderthal into the world on its own or to trap it in a laboratory where it would be poked and prodded to death.
Neanderthals on Trial | Tracing Ancestry with MtDNA by Rick Groleau In 1987, three scientists announced in the journal Nature that they had found a common ancestor to us all, a woman who lived in Africa 200,000 years ago. She was given the name "Eve," which was great for capturing attention, though somewhat misleading, as the name at once brought to mind the biblical Eve, and with it the mistaken notion that the ancestor was the first of our species—the woman from whom all humankind descended. The "Eve" in question was actually the most recent common ancestor through matrilineal descent of all humans living today. That is, all people alive today can trace some of their genetic heritage through their mothers back to this one woman. Nuclear DNA vs mitochondrial DNA When someone mentions human DNA, what do you think of? Outside the nucleus, but still within the cell, lie mitochondria. Inheriting mtDNA If you went back six generations in your own family tree, you'd see that your nuclear DNA is inherited from 32 men and 32 women[1]. Final note
Tree of Life Web Project Ten Recent Advances in Evolution By Carl Zimmer Posted 10.26.09 NOVA To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself. In some cases those insights would have given Darwin himself a pleasant jolt of surprise. Ten significant leaps forward in evolution research in the past decade, as chosen and described by noted science writer Carl Zimmer Enlarge Photo credit: (Earth) © NASA; (text) © WGBH Educational Foundation Darwin envisioned natural selection acting so slowly that its effects would be imperceptible in a human lifetime. If he were alive today, Darwin would be astonished at the pace and nature of discoveries being made in evolutionary biology, including the witnessing of evolution in action.
Top 10 Signs Of Evolution In Modern Man Humans Through history, as natural selection played its part in the development of modern man, many of the useful functions and parts of the human body become unnecessary. What is most fascinating is that many of these parts of the body still remain in some form so we can see the progress of evolution. This list covers the ten most significant evolutionary changes that have taken place – leaving signs behind them. Goose Bumps Cutis Anserina Humans get goose bumps when they are cold, frightened, angry, or in awe. Jacobson’s Organ Vomeronasal organ Jacobson’s organ is a fascinating part of animal anatomy and it tells us a lot about our own sexual history. Junk DNA L-gulonolactone oxidase While many of the hangovers from our “devolved” past are visible or physical, this is not true for all. Extra Ear Muscles Auriculares muscles Early humans ate a lot of plants – and they needed to eat them quickly enough that they could eat a sufficient amount in one day to get all of the nutrients they needed.
