description On the basis of previous studies, we searched for samples comprising supposed Paleoamerican and amerindian skulls that, in variable proportions, were discovered in the functional cranial basis America 12.sys . We worked with 49 samples randomly selected and arranged in seven sub-samples through seven groups, ordered in a decreasingly Paleoamerican proportion. The aim was to build a model that simulates a migration-replacement effect, in which Paleoamericans would be gradually banished in function of an amerindian expansion. amerindian prevalence at the end of the test would suggest that the effect considered was present, i.e. the theoretical replacement of Paleoamericans by amerindians. Only the first two samples of group I contained 100% Paleoamericans (pericues and algonquinos), while the remaining five samples of the same group were Lagoa Santa, Lauricocha, Aguazuque, Checua and Tequendama-Mosquera; all of them with variable proportions of the amerindian component. It was found that: a) Paleoamericans represented 100% at the beginning of the trial, while at the end they were reduced to 2.4%; b) This process was progressively carried out through the seven steps in which the simulation lasted, to be ended at the slowest level. We were able to reach this objective completely because there were so many samples. The Gaia index reached 97.6% of amerindian saturation, being the remnant attributed to stochastic factors. This implied that, according to our model, migration-replacement could be the possible cause of the Paleoamerican extinction, resulting from a saturation process of the amerindian component.

This implied that, according to our model, migration-replacement could be the possible cause of the Paleoamerican extinction, resulting from a saturation process of the amerindian component. Sobre la base de estudios previos, se inició una búsqueda puntual de muestras conteniendo presuntos paleoamericanos y amerindios intramuestrales que en proporciones variables se descubrieron en la base craneofuncional América 12.sys . Se trabajó con 49 muestras, ordenadas de a siete muestras por grupo, en siete grupos con contenido paulatinamente decreciente en la proporción de paleoamericanos. El objeto fue lograr un modelo que simule un efecto migración-reemplazo, en el que los paleoamericanos deberían disminuir paulatinamente en función del incremento de los amerindios. Una proporción cercana a cero al final de la prueba sugeriría la presencia del efecto buscado, esto es, el reemplazo total de los paleoamericanos por los amerindios. Sólo las dos primeras muestras del grupo I contuvieron el 100% de paleoamericanos (pericues y algonquinos), mientras que las cinco restantes del mismo grupo, fueron Lagoa Santa, Lauricocha, Aguazuque, Checua y Tequendama-Mosquera. Todas ellas con proporciones variables de componente amerindio. Fue obtenido que: a) los paleoamericanos integraban al principio del experimento el 100% de las muestras estudiadas; mientras que hacia el final del proceso quedaron reducidos a menos del 3%; b) este proceso no fue brusco sino paulatino y se hizo efectivo a lo largo de las siete etapas que demandó la simulación, a fin de llegar a un valor cercano a cien (97,6%) de saturación amerindia, lo cual implica ser causa probable —según propone el modelo— de la posible extinción de los paleoamericanos por saturación poblacional del componente amerindio. A partir de estudos anteriores, iniciou-se uma busca pontual de supostos crânios Paleoamericanos e Ameríndios, presentes na base crânio-funcional América 12.sys de dados craniométricos destinada ao continente americano. Foram estudadas 49 amostras subdividas em grupos de 7, as quais compõem a base mencionada. O primeiro resultado obtido foi que somente duas amostras paleoamericanas (Pericues y Algonquinos) apresentaram 100% dos crânios com características próprias dos Paleoamericanos. As cinco amostras restantes (Lagoa Santa, Lauricocha, Aguazuque, Checua, Tequendama-Mosquera) incluíram crânios de traços Paleoamericanos, todas elas com proporçoes variáveis de componente Ameríndio. Os resultados obtidos indicaram que: a) Os Paleoamericanos no início do experimento representavam 100% das amostras estudadas, sendo que no final do processo representavam 2.4%; b) Este processo não foi brusco, mas sim progressivo, fez-se efetivo ao longo de sete etapas, e demandou uma simulação para se chegar a um ponto próximo de zero Paleoamericanos, atribuindo 97.6% de saturação Ameríndia, o que implica ser uma causa provável da rápida extinção dos Paleoamericanos - como propõe o modelo. application/pdf http://revistascientificas.filo.uba.ar/index.php/runa/article/view/847 10.34096/runa.v30i1.847 spa Instituto de Ciencias Antropológicas, Facultad de Filosofía y Letras, UBA http://revistascientificas.filo.uba.ar/index.php/runa/article/view/847/826 RUNA, archivo para las ciencias del hombre; Vol. 30 Núm. 1 (2009); 9-27 RUNA, archivo para las ciencias del hombre; Vol 30 No 1 (2009); 9-27 RUNA, archivo para las ciencias del hombre; v. 30 n. 1 (2009); 9-27 1851-9628 0325-1217 Migration-Replacement American Aboriginals Population Theories Experimentation Migración-Reemplazo Aborígenes Americanos Teorías de Poblamiento Experimentación Migração-substitução Aborígenes americanos Teorias de povoamento Experimentação Understanding the Paleoamerican and its Probable Extinction, Through Comparative and Experimental Inferences Explicando el paleoamericano y su probable extinción, a través de inferencias comparativas y experimentales Explicando o Paleoamericano e a sua provável extinção por meio de inferências comparativas e experimentais info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículos evaluados por pares http://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=runa&d=847_oai
