Other people have already pointed out the rediculous statement regarding pangea, I'll only comment on the fossil record aspect. You can't really rely on a fossil record with hominids because we tend to favour more temperate and forested climates which don't preserve bodies very well (there are obviously certain situations such as bogs and peaty soils where this is the opposite, and incredibly lucky situations in which a body is quickly buried under a lot of sediment). So you have an abundance of preserved fossil evidence of hominids in dryer climates such as North Africa, but very little outside, which might not reflect the reality of the situation.
