Default Tiktaalik roseae fossil makes scientists re-evaluate theory about the evolution of limbs.

The Tiktaalik was a creature that, from an evolutionary standpoint, was almost halfway between lobe-finned fish (Sarcopterygii, Coelacanths) and amphibians. Originally, the theory about the development of limbs was that the fore limbs evolved first (from lobed fins such as the ones Coelacanths have) so that fish could crawl out of the water and then the hind limbs evolved to increase efficiency on land. However, with another fossil of the Tiktaalik discovered (the creature itself was discovered in 2004), scientists have begun to theorize that all four limbs evolved simultaneously.

I think it's an interesting theory....

It makes sense the way the article is describing it, seeing that they did find a pelvis that is remarkably similar to land animals. Looking at how the morphology of the way these creatures developed does give us a good idea of how these features arose. Yes, there are other "theories" of life's roots but they don't have evidence like this.

I think so too. I'd like for it to become more widely known. The evidence is hard to ignore.

Even if the internet Christians are ranting about it....
