Larger-, bipedal , particularly including the species, Homo sapiens.
It actually is an interesting question just where one makes the cut off between humans and non-human animals. In particular, were the relatively small-brained but nevertheless bipedal australopiths human or instead "simply" great apes that happened to walk on only two ?
Alternatively, it seems reasonable to consider members of genus Homo generally to consist of humans, though early members might be described as instead.
And what about the neanderthals? They (mostly) were not the ancestors of our own species, but had even larger brains as well as . Clearly, narrowly, we can equate "human" with Homo sapiens, but with increasing breadth will end up incorporating a greater of hominin species.
