I got option 3 assigned to me from Mr. Quick in this class and read the article: Traces of A Distant Past. In class we watched a movie that discussed everything that was discussed in this paper. The first main subject was the migration patterns of humans over millions of years. Evidence shows that humans started in Africa and expanded to other parts of the world through slow migrations. The evidence that proves this lies within human DNA. By looking at the DNA strands of people in the Sans tribe in Africa, scientists can observe the y chromosomes of males and see the changes over time. Scientists are creating a family tree of everyone in the world just because of there slight differences in DNA over long periods of time.
The article and movie have conclusive evidence of how humans got all over the planet over a relatively short period of time. A lot of the movement was sparked by environmental changes in their environment so they moved on looking for means of survival. Evolution was possible in humans because of this and it is why everyone is different today.
