The hypothesis of interbreeding, also known as hybridization, admixture or hybrid-origin theory, has been discussed ever since the discovery of Neanderthal remains in the 19th century. [280] The linear view of human evolution began to be abandoned in the 1970s as different species of humans were discovered that made the linear concept ...
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

The Descent of Man, and Selection in Relation to Sex is a book by English naturalist Charles Darwin, first published in 1871, which applies evolutionary theory to human evolution, and details his theory of sexual selection, a form of biological adaptation distinct from, yet interconnected with, natural selection.
The historical alternative to the recent origin model is the multiregional origin of modern humans, initially proposed by Milford Wolpoff in the 1980s. This view proposes that the derivation of anatomically modern human populations from H. erectus at the beginning of the Pleistocene 1.8 million years BP, has taken place within a continuous ...
A 2017 study of the ancient DNA of Tianyuan Man found that the individual is related to modern Asian and Native American populations. [113] A 2013 study found Neanderthal introgression of 18 genes within the chromosome 3p21.31 region (HYAL region) of East Asians.
The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003. [1]
Several writers anticipated evolutionary aspects of Darwin's theory, and in the third edition of On the Origin of Species published in 1861 Darwin named those he knew about in an introductory appendix, An Historical Sketch of the Recent Progress of Opinion on the Origin of Species, which he expanded in later editions.

Behavioral modernity develops by this time or earlier, according to the "great leap forward" theory. [70] Extinction of Homo floresiensis. [71] M168 mutation (carried by all non-African males). Appearance of mt-haplogroups U and K. Peopling of Europe, peopling of the North Asian Mammoth steppe. Paleolithic art.
