Class 12 NEET Biology Evolution Questions Part 2

The most apparent change during evolutionary history of modern man (Homo sapiens) is the increase in the brain size. The brain capacity gradually increased from early human ancestors. Homo habilis had 650−800 c.c. brain capacity which increased to 900 c.c. in Homo erectus. The true men including the living modern man also displayed the gradual increase in cranial size. The neanderthal man had 1400cc brain capacity which evolved to around 1450 c.c. (1300−1600 c.c. ) in living modern man (Homo sapiens sapiens).
