STRAND 1 PEOPLE AND POPULATION

1.1 Scientific Theory about Human Origin (Evolution Theory)

  • Developed by Charles Darwin.

  • Core argument: All organisms, incl. humans, changed over millions of years from simple → complex forms via:

    • Mutation – genetic & behavioural change.

    • Natural selection – only the "fittest" survive.

    • Adaptation – survivors adjust to new environments.

Stages of Human Evolution

(Chronological order, main traits & Africa-based discovery sites)

  • Aegyptopithecus

    • Earliest common ancestor of apes & humans.

    • Moved on four limbs; had a tail.

    • Discovered in Egypt.

  • Dryopithecus

    • Flat skull, larger canines, pointed face.

    • Quadrupedal.

    • Found at Rusinga Island (Kenya).

  • Kenyapithecus / Ramapithecus

    • Bigger teeth & jaw; larger brain; bipedal.

    • Fort Ternan (Kenya).

  • Australopithecus

    • Low/​loping forehead, projecting face, large brows.

    • Upright gait, larger brain than Kenyapithecus.

    • Sites: Ethiopia & Kenya.

  • Homo habilis ("Handy Man")

    • Longer arms, lived in families, tool user.

    • Brain > Australopithecus.

    • Olduvai Gorge (Tanzania).
