    Correct Answer: C

    Solution :

    The first human-like being was the hominid, called Homo habilis. The brain capacities were between 650-800 cc. They probably did not eat meat. Fossils discovered in Java in 1891 revealed the next stage, i.e.. Homo erectus. Homo erectus had a large brain and probably ate meat. The Neanderthal man with a brain size of 1400 cc lived in near east and central Asia between 1, 00, 00-40, 000 year back. They used hides to protect their body and burned their dead. Homo sapiens arose in Africa and moved across continents and developed into distinct races. During ice age between 75,000-10,000 years back modern Homo sapiens arose.
