Where did humans come from? How did we get to where we are now? Where are we going in the future? Studying the migration patterns of humans gives us a glimpse of the development of human civilization and shows us the patterns of human existence. Studying modern migration helps us understand complex economic systems, and it might even give us a way to ensure the future survival of the human race.

In this article, we'll examine scientific research that shows how the earliest humans spread across the globe, and we'll look at modern migration patterns. Then we'll turn our gaze to space, the future target for human migration.
