Complex skeletons evolved earlier than realized, fossils suggest
The first animals to have complex skeletons existed about 550 million years ago, fossils of a tiny marine creature unearthed in Namibia suggest. The find is the first to suggest the earliest complex animals on Earth -- which may be related to many of today's animal species -- lived millions of years earlier than was previously known.
