...there is new and powerful evidence in Tiktaalik for the steps that backboned animals took to crawl out of the sea in the first place. Many who reject evolution in favor of divine creation claim that the fossil record doesn't contain the so-called transitional species anticipated by Darwin's theory. This ancient, walking fish is yet more evidence that such an argument is simply wrong; all sorts of missing links preserved in exquisite detail have been and will be discovered...
...discovery of Tiktaalik a pivotal moment that profoundly shifts the balance in the tension between those who accept evolution and those who question it? Probably not. Those who regard creationism as dogma will probably remain unmoved by any manner of scientific evidence. For those who are uncertain, however, the fishapod may be a source of enlightenment, a demonstration that we can recover ancient clues to events clearly predicted by the theory of evolution...
...fossil, called Tiktaalik roseae, was found in rocks from the Devonian Age, which date back 375 million years. The organism’s gills identify it as a fish, but it lacks the piscatorial characteristic of a neck that is connected to the shoulder girdle, Jenkins said. The fish’s front fin contains identifiable wrist bones and features that resemble fingers, he added...
...creature, which are, described in two Nature articles released today, were dug out of rock formations on Ellesmere Island, in the Canadian Arctic, by paleontologists from the University of Chicago and several other institutions. Its nickame, for reasons that will become clear, is "fishapod"; it's more formally called Tiktaalik ("large fish in stream," in the local Inuit language). Fishapod dates from about 383 million years ago. It had the scales, teeth and gills of a fish, but also a big, curved rib cage that suggests the creature had lungs as well. The ribs interlock, moreover, unlike a fish...
