An article published in the journal “Proceedings of the National Academy of Sciences” describes a research on ancient animal fossils connected to the Cambrian explosion. A team of researchers from the British University of Oxford and the Swiss University of Lausanne carried out the most complete examination ever made of fossils of early euarthropods. The conclusions are that the origins of these animals date back to no earlier than 550 million years ago and their diversification took about 40 million years.
