I especially liked this snarky commentary from Slate.com (halfway down the page):
Scientists are trying to stop fetal sharks from eating each other in the womb. A mother gray nurse shark carries 40 or so embryos in her two wombs. But once an embryo develops jaws, it starts eating its siblings. Results: 1) Only one embryo survives in each womb. 2) The species is endangered. Solution: Scientists are developing "artificial uteruses" so each embryo can grow without being eaten by others. Crunchy spin: We're saving another of nature's creatures. Extra crunchy spin: This shark's been around for 70 million years. Don't you think nature knows what it's doing? Anti-crunchy spin: This is even dumber than paroling repeat felons.(Via Volokh.)
