It has long been a curiosity that our more distant primate cousins survive (if barely) while our closer ones, Neanderthal, et. al., are extinct. Was Homo sapiens threatened by the too-clever, too-similar relatives? When we get freaked out by robots or CGI characters that look and act a bit too human [the uncanny valley], is that awaking the ancient fear? Did we hunt them down and kill them off before they could out-compete us? It is a dark shadow in our species' dawning, and an answer we will perhaps never know.
Or were they breed into our lineages? Is there any period of recent period of change that suggests this?
What is the evidence for and against each?
Case in point and also an interesting example of our capabilities - http://www.youtube.com/watch?v=IhVu2hxm07E&feature=related
