As things get back to normal, enjoy a Wired article about weird evolutionary kludges:

6 Shark-fetus teeth. A few shark species have live births (instead of laying eggs). The Jaws juniors grow teeth in the womb. The first sibling or two to mature sometimes eat their siblings in utero. Mmm ... siblings.

7 Human stomach. People can digest a lot ? except for cellulose, the primary component of plant matter. Why don't we have commensal bacteria in our guts to do it? They're busy helping termites.
Well, our guts would need to be structured significantly differently to allow for the time it takes those bacteria to do their jobs, too.
