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.
