The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago. [ 1 ][ 2 ] The first period of the genetic history of Indigenous Americans is the determinant factor for ...
5-HTTLPR (serotonin-transporter-linked promoter region) is a degenerate repeat (redundancy in the genetic code) polymorphic region in SLC6A4, the gene that codes for the serotonin transporter. Since the polymorphism was identified in the middle of the 1990s, [ 1 ] [ 2 ] it has been extensively investigated, e.g., in connection with ...
In 2017, 5,500,000 Peruvians identified themselves as indigenous peoples and formed about 26% of the total population of Peru. [2] At the time of the Spanish arrival, the indigenous peoples of the rain forest of the Amazon basin to the east of the Andes were mostly semi-nomadic tribes; they subsisted on hunting, fishing, gathering and slash and ...
A genetic study by the same university showed that the average Chilean's genes in the Mestizo segment are 60% European and 40% Indigenous American. As Easter Island is a territory of Chile and the native settlers are Rapa Nui , descendants of intermarriages of European Chileans (mostly Spanish) and Rapa Nui are even considered by Chilean law as ...
Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes. Genetics tries to identify which traits are inherited and to explain how ...
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
