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.

This consistent pattern suggests that Spriggina preferentially turned to the right, making it the oldest known animal to display populationwide “handedness.”
Or the ones that turned left escaped fossilization 😀
