Re: Interesting use of statistics... "lies, damned lies and statistics"
That's the conventional theory - homo sapiens arrived ate all the large animals and then decided to switch to a healthy vegetarian diet once they had eaten all the meat. The problem is that there's no evidence to support it - homo sapiens was around for tens of thousands of years prior to the extinction and then, in one year, ate everything?
Fact is, nobody actually knows why, it's just a guess.
