A crucial fossil that shows how animals crawled out from the water, evolving from fish into land-loving animals, has been found in Canada.
The creature, described today in Nature1,2, lived some 375 million years ago. Palaeontologists are calling the specimen from the Devonian a true 'missing link', as it helps to fill in a gap in our understanding of how fish developed legs for land mobility, before eventually evolving into modern animals including mankind.

Paleontologists have uncovered yet another specimen in the lineage leading to modern tetrapods, creating more gaps that will need to be filled. It's a Sisyphean job, working as an evolutionist.
This creature is called Tiktaalik roseae, and it was discovered in a project that was specifically launched to find a predicted intermediate form between a distinctly fish-like organism, Panderichthys, and the distinctly tetrapod-like organisms, Acanthostega and Ichthyostega.

[QUOTE]Well, here it is in all it's beautiful glory, another piece in the tetrapod origins story has just arrived in two articles in Nature today. ... This is Tiktaalik rosae, a lobe-finned fish from the Late Devonian Fram Formation of Arctic Canada. The key features that make this animal a lobe-finned fish are the limbs which clearly have a humerus that branches out to a radius and ulna, like our own limbs. But Tiktaalik is clearly different. It has foregone a lot of the other lobe-finned fish conditions for characteristics that are much more like a tetrapod. In fact, Tiktaalik is without question the most tetrapod-like sarcopterygian known to date, and it fills an important gap in the fossil record. Clearly, it's can no longer be safely jammed into that "fish" category.[/QUOTE]

Yet another piece of evidence that support evolution.
