• Resumen

  • Kathryn Elmer of the University of Edinburgh, UK, studied how lizards re-evolved the ability to lay eggs. So her team collected 76 lizards from around Europe and carried out thorough genetic studies, looking at over 200,000 sites in the genome, to build a detailed family tree of common lizards. Live-bearing lizards evolved once from this ancestral population and split into several groups. April Wright of Southeastern Louisiana University considers this strong evidence of regaining egg-laying.
