In a genome-wide association study of 6,169 Latin American individuals, an international team of scientists identified 32 gene regions (loci) that influenced facial features such as nose, lip, jaw, and brow shape, nine of which were entirely new discoveries while the others validated genes with prior limited evidence; one of these genes appears to have been inherited from Denisovans, an extinct sister group of Neanderthals.

Dr. Kaustubh Adhikari, a scientist at University College London and the Open University, and colleagues... compared genetic information from the participants with characteristics of their face shape, quantified with 59 measurements (distances, angles and ratios between set points) from photos of their faces in profile.

They detected significant association of 32 traits with at least 1 (and up to 6) of 32 different genomic regions.

They also found that TBX15, a gene that contributes to lip thickness, was linked with genetic data found in Denisovans, providing a clue to the gene's origin.

Abstract: It has recently been shown that ancestors of New Guineans and Bougainville Islanders have inherited a proportion of their ancestry from Denisovans, an archaic hominin group from Siberia. However, only a sparse sampling of populations from Southeast Asia and Oceania were analyzed. Here, we quantify Denisova admixture in 33 additional populations from Asia and Oceania. Aboriginal Australians, Near Oceanians, Polynesians, Fijians, east Indonesians, and Mamanwa (a "Negrito" group from the Philippines) have all inherited genetic material from Denisovans, but mainland East Asians, western Indonesians, Jehai (a Negrito group from Malaysia), and Onge (a Negrito group from the Andaman Islands) have not. These results indicate that Denisova gene flow occurred into the common ancestors of New Guineans, Australians, and Mamanwa but not into the ancestors of the Jehai and Onge and suggest that relatives of present-day East Asians were not in Southeast Asia when the Denisova gene flow occurred. Our finding that descendants of the earliest inhabitants of Southeast Asia do not all harbor Denisova admixture is inconsistent with a history in which the Denisova interbreeding occurred in mainland Asia and then spread over Southeast Asia, leading to all its earliest modern human inhabitants. Instead, the data can be most parsimoniously explained if the Denisova gene flow occurred in Southeast Asia itself. Thus, archaic Denisovans must have lived over an extraordinarily broad geographic and ecological range, from Siberia to tropical Asia.Denisova admixture and the first modern human dispersals into Southeast Asia and Oceania | David Reich et al | Am J Hum Genet | Oct 7 2011
