Hominids (humans and great apes) originate in africa 6 million years ago. Branched off the evolutionary tree from chimpanzees. Humans adapt to their environments (example; in cold regions, humans have larger bones and carry more fat). Homo sapiens species emerges 150,000 years ago, creating the human species: sexual reproduction: the creation of genetically different offspring from the fusion of male and female gametes. Half of the genetic material of the offspring comes from one parental gamete and the other half comes from the other parental gamete: gametes: sex cells (either sperm or egg).
