Oldest fossils point to life on Earth 4 bln years ago: Study

The oldest fossils ever found are "direct evidence" of life on Earth 3.8 to 4.3 billion years ago, researchers reported today in the journal Nature.
Even at the lower end of the spectrum, "the microfossils we discovered are about 300 million years older" than any runners-up, said Dominic Papineau, a professor at University College London who made the discovery.
