Technically correct, since epigenetic tags can change the shape of DNA, but no, your DNA doesn't change in response to environmental conditions. Lamarck was wrong. The environment does shape your DNA's expression tho. And epigenetics can have effects for multiple generations.But your genetic code stays the same.

In plants, yes. There's no good evidence of this happening in humans. There are a handful of studies claiming to have found evidence, e.g. with the Dutch famine, but the findings are weak and they fail to rule out alternative explanations.

After a long enough period of time epigenetic changes get transferred to the genetic code of an organism, so it does change. So, Lamarck was right.

Also pretending that inherited epigenetic changes don't count because they don't change one's DNA is playing linguistic games to avoid conceding that you're wrong.

And it's peculiar that there's resistance to simply admitting that he was right. Because it's one of the most logical things nature would do.

Environmental adaptations being passed on to future generations would increase an organisms evolutionary fitness. Which makes far more sense than the illogical notion of random mutations being created and hoping that one is the right one.

Sauce? What would be the mechanism?
