Researchers have found that the cells of people who were conceived during the Great Depression, which lasted from 1929 to 1939 and, at its height, saw about 25% of the US workforce unemployed, show signs of accelerated ageing. by MistWeaver80

In rats too IIRC.

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

Sauce? What would be the mechanism?

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.
