Reading the greatest show on earth makes DNA proof of human evolution look easy. Just send off three samples for testing: 1 human, 1 chimp, 1 very distant relative e.g. fish. if the ammout of mutation differences between human and fish is the same as between chimp and fish this proves we share a recent ancestor.
Does anyone know how commecial DNA testing works and if it could be done like this for a few hundred dollars?
