OK; so I read it again . And you're right, they rule out mutation. However, they also don't talk about increased diversity. They just observe that diversity was retained, where conventional wisdom would expect it to be reduced.
Chill... take a break. "The researchers attribute this increase in genetic variety to natural selection," it's right there. I think you need some rest.
I'll get back to you on that. I'm sleepy myself.
Anyhow, whatever happend, this observation supports that genetic diversity is quite persistent. Please remind me: How is this not in support of evolution?
My main point when I posted the article was that it supported deification of natural selection. Please take care lest you inadvertently contribute to the case I'm making.
Yep. We're cool on that stuff. The "switching" effect resembles Lamarckism, and can be mistaken by the careless for "rapid" mutation/speciation. But it's just genes doing what they're designed to do. Somewhat mysterious & beautiful when properly understood. Can't say for sure, but my guess is it can take a couple (or more in the famous case of the midwife toad) of generations for recombination to cycle the genes into play. The mainstream is slow to acknowledge how much of the information is kept in reserve (in the "junk DNA"). And it's not going to be easy to figure out, either.
I'm afraid I don't remember the details, but yes, it was something about being able to turn on or off genes, due to environment pressure, and it was, among other places, observed in humans. One example is populations where the average hight is low due to poor nourishment. In modern times we have seen a number of populations that have gone from poor to good nourisment in a generation, and if the low hight was purely phenotype, you would expect the first well-nourished generation to be of normal hight. But they aren't; it takes a couple of generations.
I'm not familar with his work, sorry.
No need to dig into Lysenko, unless you plan on participating in a Lamarckist revival. Then you'd do well to take a peek at how far his crew ventured down that path already.
Catch you later - goodness I'm tired!
