It turns out that modern Egyptians and ancient Egyptians are very different. It's been widely assumed that ancient Egyptians hailed from North Africa. "In the ancient Egyptians, we don't find much at all sub-Saharan African ancestry.

Another outcome from this study is that foreign conquest didn't influence the genetic makeup of ancient Egyptians.
