QUESTION Primitive fish's sea-floor shuffle illuminates the origins of walking
“This study is the first deep foray into the origins of limb-control circuits,” says neuroscientist Joseph Fetcho of Cornell University in Ithaca, New York. There are some fish species that are more closely related to mammals that can walk on the sea floor3. But it’s “really cool” that skates, which are relatively primitive, are able to move their limbs in the same way as people do, Fetcho says. “We’re not as special as we think we are.”
