There was a rush of many homo species in the period homo sapiens came alive, all of them similar, but different in some ways, and after a while homo sapiens were the ones that got it right and got the superior neocortex compared to the other species of homo, and that's why they died out and we didn't, so in other words, the reason we have an advanced neocortex is because we evolved in a different way than the other homo species, so there is no reason why we got it, we just evolved in that way, and as a result we survived with the superior brain

The plural form of Homo habilis is Homo habilis, the plural form of Homo erectus is Homo erectus, and the plural form of Homo sapiens is Homo sapiens.

There is some dispute about the "seven" names. However, we do have "homo sapiens", "homo neandertalensis", "homo heidlebergensis","archaic homo sapiens", "homo ergaster","homo erectus", and "homo habilis".
