That is unusual. Are there so many sapient species in your dimension that share characteristics with humans? There are not many that do in Galactic Federation space. Almost all of the known species share very little among themselves, humanity included. Cylosians, Phyrgisians, Enoemas, Vhozon, Luminoth... and of course the Space Pirates, though they are less a single species and more a collective of multiple sapient species in a bid for power.
