Science Saturday: Darwin the Rock Star

[bwn]

It's interesting how horizontal evolution seems to validate the logic of some ritual cannibalism: eat another person in order to take on his attributes. I wonder what the odds are that the DNA eaten by a cannibal would get incorporated into his own DNA and benefit him, or that it would be passed on to his offspring. I'm sure they're minuscule, but it's interesting that there is any chance at all of it happening.
