World’s first right-hander could be this 550 million-year-old worm

Scientists have unearthed a 550-million-year-old fossil that might be the world's first right-handed creature, a tiny worm. This discovery indicates that the preference for right-handedness in animals could stretch back significantly further than previously thought, possibly to the dawn of complex life. Such findings could reshape our understanding of evolutionary biology and how traits like handedness have developed over geological time scales. This could have broader implications for studying the evolution of behavior in both ancient and modern species.
