DNA changes in hatcheries, interesting.

Interesting... looks like they found proof that epigenetics does indeed change the underlying DNA. So much for genetic change taking millions/billions of years... more data that doesn't support evolution.

Many fish species have been observed to undergo adaptive phenotypic gene plasticity. Pretty much a large word for "we have hidden genes you don't know about". Under adverse or different conditions epigenetic factors cause the phenotypic expression of said genes, something that actually takes a generation or two to occur (very much like the posted study). If you want to read about gene plasticity in fish here is a good article: http://www.ncbi.nlm.nih.gov/pubmed/22673650 As far as epigenetics effecting the "code" of underlying DNA, I don't believe the authors show any link between the two. We know that epigenetics has a great effect on the overall phenotypic expression due to... well epigenetic factors (methylation of DNA or genetic "switches") but the ability to physically CHANGE the genetic code is... evolution and in this case its not rapid (punctated equilibrium) its just the emergence of an older gene pool through gene plasticity.

From the press release.
"This new DNA evidence directly measured the activity of all genes in the offspring of hatchery and wild fish. It conclusively demonstrates that the genetic differences between hatchery and wild fish are large in scale and fully heritable." Quote:

Based on DME some paleontologists believe that dinosaurs were alive millions of years ago and all died out before humans arrived. But then the data rears it's ugly head and provides fresh dinosaur bones. Fresh meaning bones that showed no signs of fossilization or even the precursor to fossilization, permineralization. This would be the same as if you stumbled upon a pile of moose bones while out for a hike. The fresh Hadrosaur bone article can be found in the Journal of Paleontology via Jstor. Happened in the early 60's. Back to work for me :-) |
Tim are you a YEC?

Wow... interesting topic of discussion.
I fear that even those people who believe in evolution don't fully understand Darwin's theories. The vast majority of those asked to explain it get it horribly wrong, including myself until about 10 years ago... and I grew up with a Zoologist father. |

Wait, I can debunk all of this... 1. No one said genetic change takes millions of years. It happens generation to generation (the flu is a common example). Hell, it happens within individuals under relatively short time frames. http://www.cbc.ca/news/technology/po...find-1.1053624 2. Darwin proposed evolution. But if he recanted on this deathbed (which he didn't), it wouldn't change its validity nor the expansion of the science that has occurred since his hypothesis became theory. 3. Dinosaur soft tissue discoveries can occur due to obscure preservation events. http://www.livescience.com/41537-t-rex-soft-tissue.html Some more reading: https://en.wikipedia.org/wiki/Evolution https://www.newscientist.com/article...ft-in-the-lab/ https://en.wikipedia.org/wiki/Experimental_evolution |
