3.3-million-year-old fossilised remains of a human-like child
You tell me: ape, or human? Do you know any kids with faces like that?
What "missing link" are you referring to?
Um, the common ancestor of apes and humans (or any creature, like "Lucy" considerably closer to that branching point than modern humans) should show a mix of human and ape-like features. IOW an "apeman" of some sort, not a "monkeyman".
But, anyway, this is interesting. You seem to be saying, based on the the quote you choose, that Australopithecus afarensis shouldn't be considered an ape like human ancestor cause it's too human, or was just a human?
Are you aware that most antievolutionists dismiss all the Australopithecines as "just apes" and not human at all?
