About 400 million years ago, vertebrates first began to crawl from the primordial seas onto land. Last week, thanks to a cutting-edge mathematical-analysis technique, a global research team uncovered how a crucial stage in evolution made that advance possible. Published May 8 in Science Advances, the paper deciphers crucial information about how those sea-dwelling creatures’ fins became the specialized limbs that made life on dry land feasible.
