Although I don't believe in evolution it was quite interesting how many scientist try to figure out how human came to life and living beings. "Walking with cavemen" was very interesting. I learned about the many, so called different descendants of humans. the ones i learned about were the Homo Bosei, Habilis, Erectus, Heidelbergensis, and Neandethal. each descentant lived differently and adapted around their enviroment. These people went from being apemen in the forest, then somewhat a person in the world, eventually those that were alive then separated them selves into two differed world. One part went to the North and the other went to the south.
The north was the ice age. the south was the drought. By the end of their time, the people from the south lived(some) and started what we call the humans of todays world.
