Last time we were in class we watched a movie that was about people tracing their DNA and heritage back in time. The video stated that they think that all humans came from a common ancestor that originated in Africa. The scientist in the movie explained why people have branched out and look so different. I found their reasoning behind this to be interesting. The scientist pretty much said that people migrated and due to their migration, over a long period of time, started to change and adapt to the environment. The people adapted in several different ways. An example of people's adaptation was the fading of the skin color. Overall I found the video to be very interesting.
