Talk:Earth

Primates fist appeared in the fossil record on earth a little over 50000000 million years ago around the same time the Ancients arrived on earth presumably this is because of Ancients engineering life to evolve in to humans why then did it take 50000000 million years for humans to fully evolve to there present form on earth but it took less than 3000000 years for the same to take place on planets in the Pegasus Galaxy and why do no over planets that have been seeded with human life have any primate species besides humans
