I watched The Nature Of Things: Homo Sapiens Part 1 today.
It explained how we evolved from the great apes of 7 millions. How we evolved from Australopithecus to Homo Habilis to Homo Erectus to Homo Sapiens. It was mention that eating meat and its proteins helped gradually increased brain size of homo sapien and then they would be able to create more sophisticated tools. One scientist says that "we know evolution happened." Homo Sapiens would develop arts, religion, clothes and language during this time. They would bury the dead to perseve to memory of the dead and to fight off the anguish. This would lead spiritualism and religion.
There is discussion about if Homo Sapiens came out of Africa, evolved from Homo Erectus while they were in Europe and Asia or multi-region effect. It is noted that Homo Sapiens adapted quickly and their skin colour gradually changed as they approached colder climates. Homo Sapiens would eventually come into contact with their cousins, the Neanderthals in Europe, and Peking Man, Java Man and Homo floresiensis in Asia. They would interbreed and share customs.
Eventually, Homo Erectus and Homo Sapiens created rafts and sailed across to Australia. Since Australia has never been connected to Asia, there was no way for humans and animals to walk across from Asia. Part two is next week.
