More about Tiktaalik

Further evidence for evolutionary change between some fish 'kinds' and some land animal 'kinds' (though of course amphibians live in water too even if Genesis 1 would not tell anyone who did not already know this simple fact).

http://www.bbc.co.uk/news/science-environment-25713538
From the Abstract:
"The mosaic of primitive and derived features in Tiktaalik reveals that the enhancement of the pelvic appendage of tetrapods and, indeed, a trend toward hind limb-based propulsion have antecedents in the fins of their closest relatives".

It's true that the scientists were surprised - but evolution theory is not any way undermined by these findings even if the details may change.

Nevertheless an anti-evolution blogger, who thinks Shubin et al are part of a 'racket', is trying to muddy the Devonian waters:
http://crev.info/2014/01/tiktaalik-is-back/
"Unexpectedly, the pelvis of Tiktaalik is large and robust compared to the front limbs, looking different from both the putative ancestor and descendant".

I have recently asked Coppedge whether his is referring to Acanthostega as the assumed descendant. And whether the genus Tiktaalik were definitely extinct fish (and thus created on day five of creation week according to creationists) and not extinct amphibians created - one assumes - on day six. He has NOT replied.

Whenever his text turns green it means he has started ranting. He whines that the media are ignoring 'skeptics'. If the skeptics such as the young earth creationists actually found some science that undermined evolution they could get it past peer review and publish it in a prestigious science journal such as the PNAS, Science or Nature. Until then ...
