Alex Hrdlicka , anthropologist (Czech-American). Works: The question of man old in America (The Question of Ancient Man in America) , published in 1937 , Phase Neanderthal Man (Neanderthal Phase of Man) , published in 1927 .


The first to suggest the Asian origin of the man American was the Jesuit and anthropologist Spanish José de Acosta in his book ” Historia natural and moral of the Indies S XVI .

Samuel Foster Haven , North American anthropologist, proposed the Asian theory of the American settlement, work: Archeology of the United States ( archeology of the United States ) , published in 1856 . There he held the great antiquity of Native Americans in the territory American , postulating its Asian origin.

-In 1937 Alex Hrdlicka , taking up an argument from Samuel Haven, argued that the human being had entered America through Alaska , coming from Siberia ( Asia )], crossing the Bering Strait .


The man appears in the quaternary era, the human being had entered America through Alaska ( Yucon Valley ) from Siberia ( Asia ) approximately 10,000 years ago, crossing the Bering Strait and then dispersing throughout America. It crossed into the wisconsin interglacial (wurm). The first settlers of America were Asian paleomongoloid hunters of the Plesitocene Period . The migratory waves would have entered through the Yucon Valley, Alaska, and later dispersed throughout America.

Migration routes

  • Main route: crossing the Bering Strait .
  • Minor routes: Aleutian Islands, Kuro Shiwo stream and Negro river.


  1. Geographical foundations:
  • The proximity between Asia – America, by the strait (isthmus) behering 90 km .
  1. Anthropological foundations:
  • Asia-America breed similarity : straight dark hair , shovel-shaped teeth .
  • Wide and prominent cheekbones, eyes with a Mongolian fold, absence of beard , coppery color .
  • Polysynthetic tongue binders,
  • Mongolian spot: a congenital greenish pigmentation that Asians and American Indians have at birth that disappears over the years .
  1. Ethnological foundations:
  • A single race populated America, the Mongoloid (Asian) race. According to him, among the Indians of America ( Mayas , Quechuas or Patagones) there is a set of common characters that suggest a general common origin.
  1. Scientific foundations:
  • Archaeological remains:
  • a) Child Taber – Canada60,000 years BC
  • b) Skull of angels – California40 thousand years BC
  • Stage: Homo sapiens sapiens.
  • Period: Upper Paleolithic .
  • Organization: Bering Strait bands .

His theory was discussed by: Paul Rivet and Mendes Correia who consider that, apart from the Mongoloids, other Paleolithic migratory groups also arrived, such as Melanéesians and Australians.
