Neil Shubin, Associate Dean of the Biological Sciences Division at the University of Chicago describes how his diverse fossil findings allow him to devise hypotheses on how anatomical transformations occurred by way of genetic and morphogenetic processes.
Neil Shubin is a distinguished paleontologist whose research seeks to understand the mechanics behind the evolutionary origin of anatomical features of animals. His work focuses mainly on the Devonian and Triassic periods to understand the pivotal ecological and evolutionary shifts that occurred during that time. In 2004, after scouring the Canadian Arctic for six years, Shubin and his team unearthed the Tiktaalik roseae, a fossil "fishapod," which, despite its fish-like features, had a neck, skull, ribs, and parts of limbs similar to land animals. This discovery represents the transition between fish and four-legged mammals that occurred over 350 million years ago.
