Were doggies the killer app of cro-magnon man?
It's strange to think of dogs as a technological development, but domestication is a technology.
There's evidence that suggests that a neanderthal did about 10% more calorie burn than we do.
If we're burning fewer calories doing the same things and dogs make it easier for us to get more calories...
Neanderthal gets out competed.
Then there's the interbreeding...
I've sometimes wondered if hybrid vigor is going on and the cro-magnon appearance is a REALLY dominate gene leaving us with a magnathal who looks a lot like a cro-magnon but out competed them all.
