A strange looking ancient fish that was discovered off the coast of Canada’s Ellesmere Island tells us more than we previously knew about the evolution of limbed animals and their connection to humans.

After further investigation of a 375 million-year-old fish known as Tiktaalik roseae, discovered in 2004, it was revealed that they may have developed rear legs before moving to land.

This newest information challenges previous theories that these limbs evolved only after the move onto land.

The fossil was definitely a fish, it had gills, scales and fins, however it also had four limbs that only amphibians such as reptiles and mammals possess, including a mobile neck and a robust rib cage.
