I admit, this is way above my head. But I am interested how we, as a species, came about.
Well, yeah, it's boring and science-y. But, it does explain a few things about our origins.
It appears that modern humans may have about 2% Neanderthal as part of their genetic makeup.
Some of us, maybe more ;-)
Intersting too, is this research, that suggests we may have eaten our homonid ancestors into extinction. That, too, makes me wonder why we, as humans, are so damned cruel!
