    • They hunted with stone weapons.
    • Essentially ate fruit.
  • The first human-like being the hominid and was called Homo habilis.
    • Brain capacity was between 650 – 800 c.
    • They did not eat meat.
  • Fossils discovered in Java in 1891 revealed the next stage i.e. Homo erectus about 1.5 mya.
    • Had large brain around 900 cc.
    • Probably ate meat.
  • Neanderthal man:
    • Brain size 1400 cc
    • Lived in east and central Asia between 1, 00,000-40,000 years back.
    • They used hides to protect their body.
    • Buried their dead.
