1. The first article that I have found meaningful was “Modern Humans Came out of Africa, Definitive Study Says”. http://news.nationalgeographic.com/news/2007/07/070718-african-origin.html
This article basically says that the modern human beings originated in Africa.

For me the valuable thing about this article was that since I was in high school,
