From Laurie Sanders at Science News:
Sperm from stressed-out dads can carry that stress from one generation to another. “But one question that really hasn’t been addressed is, ‘How do dad’s experiences actually change his germ cell?’” Jennifer Chan, a neuroendocrinologist at the University of Pennsylvania, said November 13 in Washington, D.C., at the annual meeting of the Society for Neuroscience.
Now, from a study in mice, Chan and her colleagues have some answers, and even hints at ways to stop this stress inheritance. More.
Humans have similar structures to mice. Serious findings might explain a lot. How about, growing personal anxiety in the face of reduced external threats?
Remember when Darwinians were ridiculing the idea of inheritance of acquired characteristics? Me too.
Why did they do that (when Darwin didn’t)? Because they need to pretend that natural selection acting on random mutation (Darwinism) is a creative force that, magically by itself, turns cows into whales. It isn’t, it doesn’t, and it can’t.
What natural selection really means is that not all life forms survive and leave fertile offspring. That’s due to a variety of factors, including epigenetics, horizontal gene transfer, hybridization, etc. Large gaps have appeared that Darwinians can currently fill only by propaganda and legislation. That, in a nutshell, is the current evolution controversy.
Now that epigenetics is studied in much more detail, the Darwinian scam is becoming costly to all of us.
