Can a lizard lay eggs and bear live young at the same time?

These are just some of the questions that new research — including studies of a remarkable lizard that can lay eggs and bear live young at the same time — is exploring, all the while underscoring the enormous complexity and variability of sexual reproduction.

Are egg-laying mothers better than live birth?

Both birth methods get the job done, of course, but they present contrasting advantages and difficulties. Crucially, egg-laying mothers can be physically free of their offspring sooner. Birds, for instance, have never evolved live birth, possibly because the energy cost of flying while pregnant is unsupportable.
