Tiktaalik ’s ability to swim as well as support itself on the substratum underscores the idea that the mechanism that allowed vertebrates to invade ground evolve in the urine first . The unexampled material is account in a theme by Neil Shubin , Ted Daeschler , and Farish A. Jenkins , Jr. in the January 13th former online edition ofPNAS .
