Neil Shubin discovered the fossils of a primitive four-limbed vertebrate, known as Tiktaalik, in the Canadian Arctic, specifically on Ellesmere Island. This significant find in 2004 provided crucial evidence of the evolutionary transition from fish to land-dwelling tetrapods. The location was chosen due to its geological formations that were thought to contain fossils from the Devonian period, which is when these early creatures lived.
