Half a billion years before the first human reached for a tool, tiny wormlike creatures on an ancient seafloor were already curving their bodies to the right. Paleontologists studying fossils of Spriggina floundersi from the Ediacaran Period have identified the earliest known case of handedness in the animal kingdom, tracing this behavioral asymmetry to 550 million years ago. The discovery invites us to reconsider how deep the roots of our most ordinary traits truly run — and how much of what we call human was already written into life long before we arrived.
