Fish that took the first step for mankind

An evolutionary missing link that was among the first fish to leave the sea and walk on dry land has been unearthed in the Candadian Arctic, illuminating a chapter in the history of life on Earth that was essential to the ultimate emergence of humans.
Tiktaalik roseae, which lived about 375 million years ago, is a new species with features that blur the distinction between fish and terrestrial limbed creatures, placing it closer to animal lifeâ€™s transition from water to land than any known fossil.
The fossils, found on Ellesmere Island, just 600 miles (1,000km) from the North Pole, are among the finest examples of evolution in action ever discovered.
They have allowed scientists to freeze-frame a process of adaptation to land that took tens of millions of years, which made possible the development of all the mammals, birds, reptiles and amphibians that have existed since.
