Hémotypologie des populations andines et du piemont andin

Abstract

Summary. The author reports on his experience of more than ten years of investigations among the Indian populations in Latin America. The data, details of which can be found in other recent publication (J.C. QUILICI, 1975), are here analised only in relation to historical, cultural and ecological facts. At the present state of investigations, it seem that the hemotypological structure of the Amerindian populations is rather the result of their history than of ecological and cultural pressure, which seems to be of limited impact. The grade of cross-breeding between Amerindian and White or Black people can be very precisely determined because of the numerous genetic systems of the blood. On the other hand the original genetic stock of the Amerindians is remarkable because of its low degree of polymorphism, which makes it difficult to analyse the variability between native groups. Nevertheless, several hemotypological data permit the author to discuss the hypothesis of two different genetic stocks among the Amerindian populations which should correspond to two major waves of settlement of America.
