Neanderthals had outsize effect on human biology

The mouse may do everything in its power to avoid being eaten, including flinging itself off a cliff, but it's probably not a cognitive choice of "falling to my death is probably less unpleasant than being eaten by an owl." So not really suicide in the same sense.

It doesn't know its going to be eaten either, but, still it does it's utmost to avoid contact. Point is it's there as a fact. Just because one does not articulate, nor have long term awareness, doesn't remove it from being the act of killing oneself, at base, because of recognized, inbred, or gene bound, difference.
