For a primate, walking on all fours within an infinitely-lengthy environment such as a desert would be quite energy-consuming, thus bipedalism (my theory, not proven).

Total body strength, as a result of this change, became extremely devalued unlike that of the great apes. Simply look at a very strong skeleton of a modern human compared to a Homo Erectus skeleton. Similarly, look at a Homo Erectus skeleton compared to a gorilla skeleton: huge differences in bone density, cortical bone thickness, and total bone diameter.

The point is, even the most strongest of our species is quite gracile in bone structure compared to a smallish Neanderthal, so that tells quite a bit about our evolution (regarding strength).

I think it has to do with the evolution of brain size.
We learned how to use tools and team work to ease the strain of life in the wild and thus the slow loss of physical strength compared to the quick growth of mental strength. The survival of our species seem to depend on the growth of brain power then physical power. Reply
