RyanJ Posted April 6, 2006 Posted April 6, 2006 Yet another piece in the great puzzle, the puzzle of evolution. We have found many of the intermediates predicted from evolution but were missing an important one; the link between fish and land animals. Paleontologists have now found a fossil that fills in that gap, the missing link is about 375 million years old and has been named Tiktaalik roseae. http://www.sciencedaily.com/releases/2006/04/060406100543.htm - Ryan Jones
mattbimbo Posted April 6, 2006 Posted April 6, 2006 in the words of desparate dan, i have to say 'mwepps'. i think i got it wrong, a missspelling took me to this link. i guess you can figure out the rest. there is one thing i am curious about. the fossils have been dated to 375 million years ago, am i wrong but doesn't this preceed the appearance of sharks by about 200 million years? i know from research on the evolution of the immune system that the shark marks an important point. some have hypothesized this is due to the jaws, predation and ultimately an altered intake of pathogens. now i have seen the pictures, this tiktaalik beauty had a good set of choppers, so i am wondering how developed its immune system would have been compared to contemporary organisms, salamanders for example.
