  1. Human evolution -: Human evolution is the lengthy process of change by which people originated from apelike ancestors. ... Humans are primates. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship to another group of primate species, the apes.
  2. Ice age :- Ice age, also called glacial age, any geologic period during which thick ice sheets cover vast areas of land. ... The most recent periods of widespread glaciation occurred during the Pleistocene Epoch (2.6 million to 11,700 years ago).
  3. Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics
