Question

What lines of evidence support the hypothesis that modern humans evolved in Africa and then subsequently migrated throughout the globe?

Accepted Answer

Hello everyone and welcome to today's video. So what do the fossil and genetic evidence including mitochondrial DNA analysis suggests about the origin of modern humans. As answer choice is a, we have modern humans originated in Asia and immigrated to Africa as answer choice. B we have modern humans originated in Europe and migrated to Africa as answer choice. C we have modern humans evolved independently in multiple regions of the world. And as answer to is we have modern humans originated in Africa and subsequently migrated to other regions of the world. Well, in order to solve this problem, we need to understand the different types of evidence that we have for the origin of modern humans. For example, we have genetic studies and these genetic studies show that the greatest genetic diversity and the oldest lineages of modern humans are found in Africa. We also have fossil evidence which states that the earliest known modern humans lived in Africa. These are the oldest fossils that we found, but we also have mitochondrial DNA, which is passed down from mothers to their offspring. And this also supports the theory of an African origin for modern humans. As these studies have shown that all living humans today can trace their maternal ancestry back to a common ancestor that lived in Africa around 200,000 years ago. So this also points towards Africa. Now, therefore, we can state that modern humans originated in Africa and then subsequently migrated to other regions of the world, which is going to be answer choice. I really hope this video helped you and I hope to see you on the next one.
