Interbreeding between archaic and modern humans been shown that Neanderthal ancestry has been selected against in conserved biological pathways, such as RNA processing. Consistent with the hypothesis that purifying selection has reduced Neanderthal contribution in present-day modern human genomes, Upper Paleolithic Eurasian modern humans (such as the Tianyuan modern human) carry more Neanderthal DNA (about 4–5%) than present-day Eurasians modern humans (about 1–2%). Genes affecting keratin were found to have been introgressed from Neanderthals into modern humans (shown in East Asians and Europeans), suggesting that these genes gave a morphological adaptation in skin and hair to modern humans to cope with non-African environments.

Mr. and Mrs. Is the Name Mr. and Mrs. Is the Name Mr. and Mrs. Is the Name is a 1935 animated "Merrie Melodies" cartoon, starring Buddy and Cookie (as two mer-kids), and is noted to be the only Buddy cartoon in Technicolor.
