# evol: about an ancient sleep, the tendency for daytime napping, narcolepsy, and evening activities (but not red hair)

<< Interbreeding between Neanderthals and early modern humans has been shown to have contributed about 2% Neanderthal DNA to the genomes of present-day non-Africans >>

AA << found two archaic haplotypes that contribute significantly to differences in  sleep patterns >>

Archaic alleles near ASB1 and EXOC6 << are associated with a preference for being an "evening person" and an increased tendency for daytime napping and narcolepsy, respectively >>
