The scientists identified about 15 different species at the site, in addition to the ancient versions of algae and worms. The researchers said that the fossils suggest that morphological diversification of macroscopic eukaryotes may have occurred only tens...

BLACKSBURG, Va. -- Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. Now Virginia Tech paleontologists, using rigorous analytical methods, have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals. They dubbed this earlier event...
