The adaptation to cold of the Inuits comes from genes inherited from other hominids
An article published in the journal “Molecular Biology and Evolution” describes a genetic research on Greenland Inuits. A team of researchers led by Dr. Fernando Racimo of the New York Genome Center used genomic information of about 200 people and comparing them with those of a number of hominids concluded that in particular two key genes for cold adaptation were inherited from hominids called Denisovans or their close relatives.
