Evolving faster: scientists may have pushed back when complex life appeared
EDMONTON — A closer look at some unimaginably ancient fossils suggests complex life may have evolved much earlier than thought.
In a paper published today, a team of researchers say they’ve found evidence that tiny, slug-like beings were squirming around in the mud of shallow seas about 2.1 billion years ago.
Their fossilized tracks suggest they were capable of movement, a sign that life had already advanced past one-celled creatures.
