(Phys.org) —A George Washington University biologist and a team of researchers have created the first large-scale evolutionary family tree for every snake and lizard around the globe. Biologists map the family tree of all known snake and lizard groups. May 08, 2013 . (Phys.org)— A new study, published online in Biology Letters on September 19, has utilized a massive molecular dataset to reconstruct the evolutionary history of lizards and snakes. The results
The traditional studies sought explanations for how the body plans of the three dozen or so major animal groups most likely evolved, but molecular data provide strong evidence about genealogical relationships without yielding explanations. . A key assumption that biologists have relied on widely over the past quarter-century in studying the evolution of protein molecules is "highly questionable," according to an article published in the November issue of BioScience.

For decades, the story of spider evolution went like this: As insects became more and more diverse, with some species taking to the skies, spiders evolved new hunting strategies, including the ability to weave orb-shaped webs to The study is described in a July 17 paper published in Current Biology. "But the genes that were being used weren't enough to elucidate the evolution of a very diverse group like spiders, so most people dismissed many of those results.
