The nature of interaction between early humans and these sister species has been a long-standing source of controversy, the question being whether humans replaced these earlier species or whether they were in fact similar enough to interbreed, in which case these earlier populations may have contributed genetic material to modern humans.

Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.They migrated out of Africa during the Last Ice Age and had spread across Earth's continential land except Antarctica by the end of the Ice Age 12,000 years ago.
Homo antecessor may be a common ancestor of humans and Neanderthals. [40] [41] At present estimate, humans have approximately 20,000–25,000 genes and share 99% of their DNA with the now extinct Neanderthal [42] and 95–99% of their DNA with their closest living evolutionary relative, the chimpanzees.
A nomological notion of human nature – "Human nature is the set of properties that humans tend to possess as a result of the evolution of their species." [ 95 ] Machery clarifies that, to count as being "a result of evolution", a property must have an ultimate explanation in Ernst Mayr 's sense.
And in this respect, men do not differ from animals, some with respect to others, although they do not arrive at the same extremes. In short, God has disposed some human beings as a cause of life for others, and likewise, he has disposed the latter as a cause of the death of the former." [42] Al-Jāḥiẓ also wrote descriptions of food chains ...
Human beings, writes social anthropologist Ernest Gellner, are not genetically programmed to be members of this or that social order. You can take a human infant and place it into any kind of social order and it will function acceptably. What makes human society so distinctive is the fabulous range of quite different forms it takes across the ...
Evidence as to Man's Place in Nature is an 1863 book by Thomas Henry Huxley, in which he gives evidence for the evolution of humans and apes from a common ancestor. It was the first book devoted to the topic of human evolution, and discussed much of the anatomical and other evidence. Backed by this evidence, the book proposed to a wide ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.
