Walking with Cavemen
I watched Walking with Cavemen last night. I found little new information than previous specials about Lucy, Neanderthals and Cro-Magnans. But nevertheless, it was interesting. Now the mind boggling question is that for a million years, direct ancestors of cro-magnans could not improve stone-based axes, but they (cro-magnans) made a big leap towards development of tools, arts and language. Was there an outside intervention?
