So far, there's a lot of very human-like species in the RP so that alone is a shocking coincidence already. To clarify though, I don't think it's a problem at all -- and so I don't think it's a problem for someone to play other humans, as there's a lot of people(including myself) who are pro-human.

Although the likelihood of humans developing on a different planet with a completely different ecosystem and with completely different catastrophic natural disasters(ice ages, stuff like that)... Is really improbable. I think it's fair for a small part of humanity to disappear from Earth during their space fairing age to go their own separate ways. The only issue is you'd be extremely far back in population numbers, and well.. You get the picture.
