MENENDEZ, Lumila Paula; LOPEZ SOSA, María Clara  y  SOLARI, Ana. Morphological affinities of the early/middle Holocene skeletons from North America and South America:. Runa [online]. 2022, vol.43, n.2, pp.57-85.  Epub 27-Jun-2022. ISSN 1851-9628.  http://dx.doi.org/10.34096/runa.v43i2.10882.

The aim of this work is to carry out a comparative analysis of craniofacial morphology in a sample of 92 individuals from the early/middle Holocene from South and North America with the purpose of discussing both the biological diversity present in the early Holocene individuals from the American continent, as well as the expansion dynamics occurred during the early and middle Holocene, by using multivariate ordination techniques and calculating biological distances. Our results show a moderate geographic structure between the samples from eastern and western South America, in which the sample from North America is in an intermediate position between both, and presents larger similarities with the samples from the west. Individuals from the Argentine Pampas show similarities with those from Brazil but also with individuals from Chile and Colombia. We conclude that the morphological diversification between the populations of eastern and western South America occurred early, and some regions such as the Argentine Pampas received the contribution of different ancestral lineages.

Palabras clave : Craniofacial morphology; Peopling of the Americas; South America; North America.
