Evidence for the evolution of Homo sapiens from a common ancestor with chimpanzees is found in the number of chromosomes in humans as compared to all other members of Hominidae. All hominidae have 24 pairs of chromosomes, except humans, who have only 23 pairs. Human chromosome 2 is a result of an end-to-end fusion of two ancestral chromosomes ...
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.
The MUH is based on the radical Platonist view that math is an external reality. [3]: sec V.C However, Jannes [13] argues that "mathematics is at least in part a human construction", on the basis that if it is an external reality, then it should be found in some other animals as well: "Tegmark argues that, if we want to give a complete ...
3.5–3.0 Ma Kenyanthropus platyops, a possible ancestor of Homo, emerges from the Australopithecus. Stone tools are deliberately constructed, possibly by Kenyanthropus platyops or Australopithecus afarensis. [34] 3 Ma The bipedal australopithecines (a genus of the subtribe Hominina) evolve in the savannas of Africa being hunted by Megantereon.
The mathematics lead to a modified version of Hamilton's rule where: q>c/b where q (the probability of knowing the social score) must be greater than the cost benefit ratio [ 36 ] [ 37 ] Organisms that use social score are termed Discriminators, and require a higher level of cognition than strategies of simple direct reciprocity.
paleoanthropology and paleontology of both human and non-human primates; primatology and primate ethology; the sociocultural evolution of human behavior, including phylogenetic approaches to historical linguistics; the cultural anthropology and sociology of humans; the archaeological study of human technology and of its changes over time and space
In 1972, George R. Price showed that Fisher's theorem was indeed correct (and that Fisher's proof was also correct, given a typo or two), but did not find it to be of great significance. The sophistication that Price pointed out, and that had made understanding difficult, is that the theorem gives a formula for part of the change in gene ...
Evolution and natural selection has been applied to the study of human communication, mainly by Charles Darwin in his 1872 work, The Expression of the Emotions in Man and Animals. [1] Darwin researched the expression of emotions in an effort to support his materialist theory of unguided evolution.
