So, homo rudolphensis and homo habilis are, a, both forms of homo erectus, b, often considered the same species, immediately ancestral to homo sapiens, c, often combined into homo habilis, or d, often combined into australopithecus robustus.
00:20
So, we've got a few different species being described here.
00:24
We have homo rudolphensis, homo habilis, homo erectus, and australopithecus robustus.
00:30
First of all, rule out a robustus, because that's a different genus altogether.
00:36
That's more ancestral.
00:38
And labelis and rudolfensis, they are different to that.
00:42
So they are more, more upright, larger brains.
00:47
So they are distinct from the australpificus genus.
00:51
Are they forms of h.
00:52
Erectus? no.
00:56
They are not forms of h.
00:57
Erectus.
00:58
Because h.
00:59
Erectus has a larger brain, and it is more fully committed to bipedalism.
01:08
So it's more bipedal than these earlier species.
01:16
So bipedalism started with the ostropipithecus venus with, for example, afrikanus, but slowly developed, and by hemo -erectus, you had a fully bipedal skeleton, and also a flattening of the face, like we see in modern humans.

So, too much...
