I haven’t got a formal list, but I’ve read lots of different (and equally foolish, IMHO) reasons for the supposed demise of Neandertal. Here’s some off the top of my head.
- couldn’t talk (which means, couldn’t yell, “stop, don’t kill me”?)
- couldn’t talk well enough (after it was finally accepted that N could talk)
- couldn’t walk (or rather, couldn’t walk ‘right’)
- couldn’t walk fast enough
- ate too much meat, not enough fish
- couldn’t hunt
- couldn’t compete
- couldn’t adapt to the cold
and today...
- couldn’t sew, and therefore froze to death
My theory is they just ran out of beer!
