      Bizarre DNA of Platypus tells a story about us

      Posted by Jeff from Seattle Times

      There are genes for egg laying, evidence of the animal\\\\\\\'s reptilian roots. Genes for making milk, which the platypus does in mammalian style despite not having nipples. Genes for making snake venom, which the animal stores in its legs. And there are five times more sex-determining chromosomes than scientists know what to do with.

      Upright Walking Began 6 Million Years Ago, Thigh Bone Comparison Suggests

      Posted by Sandyenglish from Science Daily

      A shape comparison of the most complete fossil femur (thigh bone) of one of the earliest known pre-humans, or hominins, with the femora of living apes, modern humans and other fossils, indicates the earliest form of bipedalism occurred at least six million years ago and persisted for at least four million years. William Jungers, Ph.D., of Stony Brook University, and Brian Richmond, Ph.D., of George Washington University, say their finding indicates that the fossil belongs to very early human ancestors, and that upright walking is one of the first human characteristics to appear in our lineage, right after the split between human and chimpanzee lineages. Their findings are published in the March 21 issue of the journal Science.

      Birds Do It. Bees Do It. Dragons Don’t Need To.

      Posted by Jeff from New York Times

      But these eggs — two of which hatched a few weeks ago — were unusual: they developed from a female that had had no male of the species in close proximity for more than a decade. Judging from similar occurrences over the past two years in Britain, it appears that these lizards sometimes use a form of virgin birth in which eggs hatch without conception. The embryos are genetic clones of the mother.

      Giant Frog Jumps Continents

      Posted by okami

      A giant frog fossil from Madagascar dubbed Beelzebufo or `the frog from Hell' has been identified by scientists from UCL (University College London) and Stony Brook University, New York. The discovery of the 70 million year-old fossil frog, of a kind once thought unique to South America, lends weight to a new theory that Madagascar, India and South America were linked until late in the Age of Dinosaurs.

      The Family That Walks On All Fours

      Posted by robynoratocom

      A documentary film on a family living in remote Turkey aired on BBC in 2006, and again on NOVA a few months ago. Why should we care about this Muslim Turkish family? Because several of the many siblings walk on both their hands and their feet, a way that humans have not walked for millions of years. Are they the key to unlocking the course of human evolution?

I love to read, and write, and sip tea while curled up on the couch :)
