hippy-
do u even lactase persistence?
Yeah, but that occurred in completely different conditions to the present day, i.e. a much smaller population under greater stress, coupled with a new technology (herding) which made the mutation tremendously advantageous. That allowed a relatively small genetic mutation to be exploited to out-breed genetic lines lacking lactase-persistence. Modern humans are seldom isolated for long in small highly stressed groups where something substantial could evolve, and even when they are they promptly go on holiday and start fucking the locals and differences between populations get smoothed out.

They've been parked for a long time now. Don't confuse freaks with populations, or epigenetics with genetics. Large populations and rampant miscegenation (sapiens couldn't even keep his hands of neanderthalenis, or vice versa) makes any substantial population wide evolution unlikely for the time being, but outliers will always occur and technology (training and nutrition) can reveal human potential which was always there but not previously expressed.
