YAHOO NEWS - Fossils from South Australia are offering a surprising clue about the deep history of animal behavior.
Spriggina floundersi, an ancient organism that lived about 550 million years ago, may represent the oldest known example of "right-handedness" in animals, suggesting a preference for turning right emerged long before hands, feet, or widespread complex body plans.
What happened?
According to research published in the journal Scientific Reports, Spriggina floundersi may preserve the earliest identified sign of population-level handedness in animals. The study involved scientists from the American Museum of Natural History, Florida State University, Harvard University, and the University of California, Riverside, and was highlighted by Neuroscience News.
