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. Now your playing a really interesting card here Tim, I'm always open for a good discussion so if you would be so kind to elaborate your thoughts on this statement? |

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. |

Tim, I am strongly urging you to take a look at the articles I previously linked in my footnotes. I suspect that you may have in incomplete picture of what the theory encompasses or how much of a fundamental keystone it is to modern science. Don't do it man! Evolution is awesome! Be awesome!

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

http://www.cbc.ca/news/technology/po...find-1.1053624 Interesting article. Just more evidence that genetic change happens quickly. Which I happen to agree with. Some people call that micro evolution and I'm fine with that term. Quote:

Here's an interesting article as well: http://www.nature.com/news/dna-has-a...f-life-1.11555 If you read it check out the part by Simon Ho. He is a good example of how evolutionary dogma is clouding his thinking. His reasoning is as follows: There can't be DNA found in dinosaurs or insects trapped in amber as they are at least 65 million years old and we know any bits of DNA code are less than 500,000 yrs old. An unbiased scientist would say something like. Test the dinosaurs and amber trapped insects for dna. If you find it then we know they are less than 500,000 yrs old. If there's no DNA found then there's no issue. I'll read the rest of your links later. Quote:
Evolution = non observable and non repeatable which requires faith to believe exists/works. Hence a belief system. Gravity = observable and repeatable results Particle Physics = observable and repeatable results True science is based on Observable and Repeatable results. Evolution is a hypothetical science that violates known LAWS of the universe. ie 2nd Law of Thermodynamics. Darwinian Macro Evolution is a house of cards just before a wind storm. Get out quick Albert. ;^) Even Richard Dawkins is running. Here's an interesting exchange where he endorses intelligent design and then goes on to say the higher intelligence must have come about via Darwinian Evolution. http://www.c4id.org.uk/index.php?opt...test&Itemid=28

It is.

Einstein is dead. He won't be making any revisions to anything. Regardless, this is a strawman, no one is arguing for relativity. Science is additive and if new and better information supplants older information, then it adopts the best fit. This is how the knowledge pool is expanded. Quote:
