The study of archaic hominid populations is one of the major topics in the field of human evolution. The negroid race, depending on the population, has 2% to 19% of archaic hominid genes - whose DNA is absent in other races. Records are being broken by Kenyan Luhya negroids - the concentration of hominid genes in the population there reaches 31%. Geneticists are trying to identify these archaic groups, which have left traces in the genomes of modern negroes. The new research suggests that arachaic human (and other hominid) populations may have lived in a network of groups that have not interbred with archaic hominids for the past million years.
