Evolution Before Our Very Eyes: A Lizard with a Placenta!

  • Something fascinating has been discovered. Trachylepis ivensii is a small  African lizard that uses a placenta to nourish its young before they are born. A number of lizards give live birth, but the fetus' nourishment normally comes from a large egg yolk.  This little animal's fetus is nourished by blood vessels in the uterine wall in much the same way as a human's fetus is!  Apparently nobody has described this reptilian feature before.  See a picture and the article in Discover Magazine, October 2011, P. 18.  (Sorry--no working link is currently available.)
