Radiocarbon dating bone collagen
A simple way to think of evolution is "descent with modification" — over many generations, organisms change into something different.
Then Adam and Eve started a family and left plenty of descendents.He figured out that rocks are deposited in layers with older rocks at the bottom, and in the landscape of Tuscany, he thought he saw the events described in Genesis.In the century following his death, however, people who searched rock layers for remains of Earth's earliest inhabitants found something odd.Really far back in time, there wouldn't be any legs at all, just fins for swimming.Evolutionary theory argues that all the organisms alive on Earth today share a common ancestor.
