Reply to comment by venetian_lemon in How the Great Depression shaped people’s DNA. 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

There really is no such thing, even traits that we often consider disorders such as ADHD or being in the Autism spectrum can lead to increased fitness under the right evolutionary pressures.

I'm not sure genes work that way. It is no longer a natural selection process; those genes won't be weened out quite like hundreds of years ago. The only way I see it as possible would be to also introduce gene correction - and religious folks don't like people playing God.

Edited: And yes, environment plays a role in development as previously pointed out.

I guess the God fearing folks don't like the idea of playing God. It's only a matter of time before a culture or country starts correcting genes to create a more well rounded diseaseless as possible people. Anyone think China isn't already on top of this? It's already been done before, rogue scientist or not (HIV immune twins). Yeah they have a decreased lifespan of 20%, but the proof is there. If CRISPR mutates inert genes though, that could prove problematic in the future evolution of humans.

ADHD can be caused by a pregnant woman living in a loud environment with very few quiet moments. Something about the noise during the first trimester changes the way the fetus develops.
