Julie W. B. Sikes Interdisciplinary Science II Science News 6 From Sea to Sand Prior to being released only yesterday, the only evolutionary link between fish and land creatures had been a double-paired fin fish dubbed Tiktaalik Roseae . But now Swedish researchers Per Ahlberg and Henning Blom from Uppsala University have discovered a 370- million year old skull and shoulder bone of a walking fish, known as Ventastega Curonica . -Uppsala University (2008, June 25). “Closing the Gap Between Fish and Land Animals”. Science Daily . Retrieved June 26, 2008, from: http://www.sciencedaily.com /releases/2008/06/080625140643.htm This “walking fish” lived during the Devonian period and is known as one of the earliest forms of tetrapods, (the first animals adapted to land). Te creature had a head with razor-like teeth, but the body of its fish-like predecessor the Panderichthys . This new found creature also had flippers in order to maneuver through the swamps in search of prey.

Rather than evolving in a simpler linear fashion, as thought, they now realize the complications of the process. This could only be one of many steps in our evolutionary process to be found.-(2008, June 35). Fish out of water: The Evolutionary Crawl from Sea to Land. Agence France Presse .
