Last Humans Standing

"Last Human Standing." Becoming Human. PBS NOVA. 31 Aug. 2011. Television.

You might be asking,"Why are we the only humans left what about Homo erectus, Neanderthals, or Homo hidelberg?". Well this question has many different answers, all of them might not be correct because, we cannot just go back into the past and see why they died out, we have to make inferences on what evidence we have. As far as we know, two major factors that helps us survive are; our changed diet and climate change. During an ice age Homo Sapiens moved to the water. That helped them improve intelligence. That is because, they got food from the ocean. To do that they had to know when the tide would be low so it was safe for them to catch food. For that they studied the pattern of the moon, so we started to get more intelligent. The way that diet changed us was that; when we moved to the water we started eat sea food because that was the food there. We had to start making new tools to survive, and they were for fishing and other ways of getting food. This also increased their intelligence into what we are now. Why we are the only human that survived, there are so many ideas we might never know why....
