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, [22] 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.
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.

Robert Boyd and Peter J. Richerson, two strong proponents of cultural evolution, postulate that the act of social learning, or learning in a group as done in group selection, allows human populations to accrue information over many generations. [51] This leads to cultural evolution of behaviors and technology alongside genetic evolution.
EDP theory diverges from mainstream evolutionary psychology in both the degree of importance placed on the environment in influencing behavior, and in how evolution has shaped the development of human psychology. [5] Advocates of EDP assert that evolutionary psychologists, while acknowledging the role of the environment in shaping behavior and ...
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
