Single Migration Term Papers

On Wednesday, September 21st, three separate teams of geneticists concluded that all non-Africans today trace their ancestry to a single population emerging from Africa. Every study of DNA support this claim, stating that all non-Africans are closely related to one another, all branching from a family tree. The estimate era of the single migration of early humans in Africa is determined to be somewhere between 80,000 and 50,000 years ago, but more studies found a small percent to be much older, as far as 140,000 years ago. All this data resolved the question of human evolution and our population spread across the globe, and more knowledge to adaptation and evolution. However, I have questions about this controversial single migration, especially due to it being described as controversial, yet I have not heard of it before. My thoughts regarding the origins of man concern the reason why the first migration left Africa in the first place. Carl Zimmer states that computer models of Earth’s climatic and ecological history shows changing rainfall patterns periodically opened from Africa into Eurasia that humans may have followed in search of food. However, that is the only information provided by Zimmer, meaning that there could be countless of other reasons why the migration occurred - even perhaps reasons to why the migration was unnecessary. No data stating the
However, one single answer does not fulfill all the reasons and morals to this specific question. Leaving Africa could have been a search of food, but there are a multitude of other reasons that lead to the first migration, whether it was tribal or environmental issues. All these unanswered questions link to that single question - “Why leave Africa at all?” Perhaps someday researchers will unravel the history of the early humans of Africa, but for now, we can all consider ourselves partially
