Egg, live births, pregnant males, oh my!

I'll just leave this here: https://www.quantamagazine.org/egg-laying-or-live-birth-how-evolution-chooses-20....

Mind. Totally. Blown.

>1 haydninvienna:
Very interesting article. Thanks for posting.

Thumbs up on the article, I wonder if an egg is the first meal for a live birth when there is a mixture of live births and eggs? Gruesome but starting out with a full tummy might be an advantage.

>3 DugsBooks: It's worse than that. Many species of sharks are live-born, and I remember reading that nearly-full-term embryos are known to cannibalise each other.
