    Default Lizard species evolving to give birth

    http://news.nationalgeographic.com/n...ve-birth-eggs/

    ^ Pretty cool stuff. An Australian Lizard species is transitioning from laying eggs to giving birth. And it's happening before our eyes!

    "Now we can see that the uterus secretes calcium that becomes incorporated into the embryo—it's basically the early stages of the evolution of a placenta in reptiles," Stewart explained.
    In general, the results suggest the move from egg-laying to live birth in reptiles is fairly common—at least in historic terms—because it's relatively easy to make the switch, Stewart said.

    Damn, the link to the article nat.geo cited at the end is only the abstract. I need more information about the viviparous and egg-laying populations and their interrelations, as in interbreeding, and whether if you transplant members of one population to the others' environment if they adapt to the new reproductive strategy. Thanks for posting! *off to read more*
