Ardi - aquatic?

I'm confused as to the standpoints of proponents sometimes.
Algis, in your opinion, was Ardipithecus ramidus semiaquatic?

Me too, Chris.

I think the australopithecine grade hominins (and as far as I can tell ardipithecus were somewhere on that branch, earlier) were wading-climbing bipeds. So I don't know if that classifies them as "semi-aquatic" - I think not.

I suppose the key question I'd ask is how much of the bipedality of the earliest hominins was wading. Seasonally flooded gallery forests offer the perfect scenario, in my view, for hominin bipedality to evolve. I think the evidence is consistent with that.

Waterside hypotheses of human evolution assert that selection from wading, swimming and diving and procurement of food from aquatic habitats have significantly affected the evolution of the lineage leading to Homo sapiens as distinct from that leading to Pan. (p118)
