In early stages, human beings resembled

Meghna Thapar 5 years, 1 month ago

About 1.9 million years ago, Homo erectus evolved. This human ancestor not only walked fully upright, but had much larger brains than Homo habilis: nearly twice as large, on average. Homo erectus became the first direct human ancestor to leave Africa, and the first to display evidence of using fire.

Evolution involves the gradual changes from simple to more complex forms. Humans are believed to have developed from simpler forms.
Evolution is the result of the interaction between the following five processes:

  • Mutation.
  • Genetic Recombination.
  • Chromosomal Abnormalities.
  • Natural Selection.
  • Reproductive isolation.
