As per our biology textbook, the sequence is Australopithecus with 400-500cc brain volume, then Homo habilis around 600-700cc, Homo erectus near 1000cc, and finally Homo sapiens with 1300-1400cc. But bhaiya, after seeing the skull replicas at the CSMVS museum in Mumbai, I realise the brain size progression is too tidy; fossils like Homo naledi with small brains existed alongside others, challenging this linear path. My teacher, Mr. Deshmukh, emphasized that Indian sites like Hathnora show mixed traits, so I think our charts oversimplify the real, bushy evolution.
