Scientists from Southwest China's Yunnan Province published a significant study in journal Science on Friday, unveiling the origins of Shishania aculeata, a species of mollusk existing 514 million ...

Kamptozoa and Bryozoa are two phyla of small aquatic invertebrates that are related to animals like snails, earthworms, leeches, and ribbon worms. But questions surrounding the precise location of ...

New fossils of the first land animals reveal that ancient shores were alive with more crawling, slithering creatures than anyone previously thought. In the late Cambrian era, nearly 500 million years ...
