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 ...
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture continually interact in a feedback ...

Peru is the fourth most populous country in South America. [19] Its demographic growth rate declined from 2.6% to 1.6% between 1950 and 2000, and its population is expected to reach approximately 46 - 51 million in 2050. [20] As of 2017, 79.3% lived in urban areas and 20.7% in rural areas. [21]
Blending inheritance. Flowers would converge to a single coloration in a few generations if inheritance blended the characteristics of the two parents. Blending inheritance is an obsolete theory in biology from the 19th century. The theory is that the progeny inherits any characteristic as the average of the parents' values of that characteristic.
e. Peruvian cultureis the gradual blending of Amerindian cultures with European and Asian ethnic groups. The ethnic diversity and rugged geography of Peruallowed diverse traditionsand customs to co-exist. Peruvian culture has been deeply influenced by Native culture, Spanish culture, and Asian culture.
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 ...
