00:00This is why everyone on Earth is your cousin.
00:02That's you, your two parents, your four grandparents, your eight great-grandparents.
00:06And if you go back like that, 40 generations,
00:08Logically, you should have 10 billion ancestors all living at the same time.
00:12But that's impossible, since in the whole of human history, there have only been 100 billion
00:15of humans.
00:15This means only one thing: you are a son of incest, or a daughter, and so am I.
00:20Because otherwise there would be many more humans on Earth.
00:22But above all, it means that we all share a common ancestor.
00:25So who is it?
00:26The mistake would be to think that it's Charlemagne.
00:28Because yes, good news, you are a descendant of Charlemagne.
00:31So you can claim the throne of France, since...
00:33Charlemagne is a great ancestor; he had at least 5-6 wives.
00:36and always a minimum of 13 children who have themselves reached the age of having children.
00:40You descend from him by hundreds, by thousands of branches.
00:42The problem is that it only works if you are of European origin.
00:45So who is our common ancestor, the ancestor of all humanity?
00:48Three researchers investigated, and here's what they found.
00:50We only need to go back 2000 years to find we all have the same ancestor.
00:54Which is already incredible.
00:55Then our ancestor must have lived in East Asia so that his descendants could have traveled to Australia and
00:59in America.
01:00And spread its genes.
01:01And most importantly, it had to be someone who was very productive.
01:04So this is a family portrait.
01:06And that's your racist uncle.
01:08And everything that was supposed to be important.
