Probabilités appliquées: un ancêtre commun


Une belle application des probabilités. Tous les humains vivants en ce moment auraient un ancêtre commun. L'article vaut la peine d'être lu.

this was the ancestor of every person now living on Earth — the last person in history whose family tree branches out to touch all 6.5 billion people on the planet today. That means everybody on Earth descends from somebody who was around as recently as the reign of Tutankhamen, maybe even during the Golden Age of ancient Greece. There's even a chance that our last shared ancestor lived at the time of Christ.
