Genetics, I think, resoundingly has answered the question of where we ultimately came from, we came out of Africa. And we came out quite recently, within the last 50 or 60 thousand years,

What if I told you every single person in America - every single person on Earth - is African? With a small scrape of cells from the inside of anyone's cheek, the science of genetics can even prove it.

This is a giant leap forward for field expeditions everywhere,

We are going through a process of mass cultural extinction.

If you go far enough back, your genome connects you with bacteria, butterflies, and barracuda - the great chain of being linked together through DNA.

It turns out that every person alive today can trace his or her ancestry back to Africa. Everyone's DNA tells a story of a journey from an African homeland to wherever you live.
