(PhysOrg.com) -- In a new study published in the Proceedings of the National Academy of Sciences, biologist David Hillis from the University of Texas shows how the freshwater Corbicula clam utilizes rare gene capture to avoid ...
About 1.5 to 2 billion years ago, the great evolutionary 'big fish, little fish' engulfment occurred. Somehow, scientists think, one bacteria swallowed another, creating a new type of cell, the eukaryotes.
