EUREKA ALERT! - Scientists have uncovered what may be the earliest evidence of “right-handedness” in the animal kingdom, dating back more than half a billion years.
The discovery comes from the fossil record of Spriggina floundersi, an organism from the Ediacaran Period that lived about 550 million years ago. New research published today in the journal Scientific Reports and led by researchers at the American Museum of Natural History, Florida State University, Harvard University, and the University of California, Riverside indicates that Spriggina showed a consistent preference for bending to the right.
