"Out with the old, in with the older": Theories on Archaeology in 2020+

Lucy, the Australopithecus, was discovered just in 1974, in Hadar Africa. And she had lived 3.2 million years ago! That's a lot! Of course, if you had been there the day her remains got dug up. Whop! Here comes the Ardipithecus ramidus. The missing link, so long. "Ardi" had lived 4.4 million years ago. (Many more discoveries had been made.) Q: How old will fossils be in the year of 2020? Few scientists say our origins can grow all the way up to 6 million years. Oops. Digging up roots in your backyard when you find the pelvis of the oldest Australopithecus right under your blue violet!
