Resumen
El análisis genético revela el contacto prehistórico entre las poblaciones polinesias y nativas americanas alrededor del año 1200. Esta evidencia apoya las antiguas interacciones transpacíficas, desafiando los debates anteriores sobre los orígenes de los cultivos del Nuevo Mundo en Polinesia.
Área de la Ciencia:
- Genética de las poblaciones
- Arqueogenética
- La migración humana
Sus antecedentes:
- El potencial para el contacto de viajes prehistóricos entre las poblaciones polinesias y nativas americanas sigue siendo un tema de debate científico.
- La evidencia como la presencia de cultivos del Nuevo Mundo (por ejemplo, la batata dulce, la calabaza de botella) en la Polinesia ha alimentado las teorías de contacto transpacífico.
- Los estudios genéticos anteriores han dado resultados contradictorios, dejando la cuestión sin resolver.

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

01:09Mutation, Gene Flow, and Genetic Drift
61.4K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

01:31Formation of Species
44.3K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

02:16Genetics of Speciation
20.7K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

03:33Genetic Drift
42.6K
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.
