At coasts, rivers & wetlands, they collected (through diving & bipedal wading & beach-combing) shallow aquatic & waterside plant & animal foods, which contained the necessary brain-specific nutrients for brain expansion, e.g. long-chain poly-unsaturated fatty acids (LC-PUFAs, e.g. DHA).
Comparative data confirm that a coastal dispersal model is the easiest way to account for Homo’s thick & heavy bones (pachy-osteo-sclerosis), external nose & mid-facial prognathism, long & straight legs, broad bodies & pelvises, large & linear bodies (head-spine-legs in 1 line), brain expansion, tool-making & increased consumption of animal foods.

The climate has been changing for the past millions of years because it is a natural cycle on Earth.
Take THAT! Al Gore!

This should be science fiction, not science, but then again, it is coming from the Smithsonian.

Just write the papers..The evidence will come. Darwin and Haekel and the others understood this.

It is well known, and has been for some time, that the ability to walk upright evolved much more rapidly and far earlier than did large brains.
