Professor Neil Shubin talks about the discovery of Tiktaalik and one of the greatest evolutionary events in Earth's history: when the very first fish ventured out onto land. • You can buy Neil's book Your Inner Fish: The amazing discovery of our 375-million-year-old ancestor now - https://geni.us/a2fNf8 • Widely known as the fishapod , Tiktaalik roseae is a 375 million year old fossil fish discovered by a team of six palaeontologists in the Canadian Arctic in 2004. • Tiktaalik looks like a cross between the primitive fish it lived amongst and the first four-legged animals, a group called tetrapods . Derived from tetra- , meaning four, and -pod , meaning foot, all animals that descended from these pioneer amphibians, including us, can be called tetrapods. • Tiktaalik lived about 12 million years before the first tetrapods (which are approximately 363 million years old). With the earliest appearance in the fossil record of tetrapod features in a fish, the discovery has become a key piece of evidence in the transition from life in water to life on land. • Watch more footage from the interview with Neil Shubin: • • Finding Tiktaalik (Additional Material) • The Ri is on Twitter: / ri_science • and Facebook: / royalinstitution • and Tumblr: / ri-science • Our editorial policy: http://www.rigb.org/home/editorial-po... • Subscribe for the latest science videos: http://bit.ly/RiNewsletter • Product links on this page may be affiliate links which means it won't cost you any extra but we may earn a small commission if you decide to purchase through the link.
