Discovery of new fossils in Northwest Canada changes view of early animal evolution (opens in new tab)

Researchers have uncovered a remarkable fossil site in a remote part of Canada's Northwest Territories, offering unprecedented insight into the earliest evolution of complex animal life on Earth. Findings from the site represent life from the Ediacaran biota—soft-bodied organisms that lived on the seafloor more than 500 million years ago—and push back the origins of animal movement and sexual reproduction by 5–10 million years.
