We have no evidence of any exponential or even mild "evolution" in the nature, minds, or bodies of men and women in recorded history of about 6000 years. If this were true it would be self evident, and the variety of humans would include greater distinctions and contrasts, of which we have none.

Evolution unfolds along multiple paths. Some of the paths can be exponential in terms of the rate of change. For evolution to become exponential it should 'jump' medium, as for example from evolution through genes, to cultural evolution through language.

Hmm, Thousands of years...VS....Millions of years....Hmmm

Perhaps our frame of reference is just too short
