>Evolution tends to allow one species per niche.
I'm not going to dispute this like >>8045030 did by simply claiming that it's false. I understand the concept of niche differentiation in ecosystems, but my original post about the hominid genera having only one species left isn't directly related to that concept.
What I was saying is that as a species, we've demonstrated complete intolerance of all other human species, not to mention almost all other megafauna that were on this planet before sapiens arrived.
Any peaceful intelligent life out there that have done their research on us would certainly steer clear of a psychopathic and narcissistic species such as homo sapiens. So that pretty much narrows our encounters to the non-peaceful intelligent life.
