although it's like milk too. exposure at an early age leads to the body producing more lactase enzyme to digest it. but lack of exposure often makes people lactose intolerant.

I agree. The example with Nicotine intake having a somewhat positive effect on the children feels too wild at the money. Think of all the kids of the 60th and 70th. They must be immune to most toxins ;). Yes I take this example to the extreme. I also feel that this could maybe contradict what we learned from evolution theory. Why would it take so long for a given treat to establish itself. Maybe I mix too much into o…

Allergies and cancer are way up.

There’s multiple causes behind those, this is almost certainly one.

If you ignore "good" and "bad" then it's just "traits can be passed through this mechanism" egg seems a lot more reasonable.

Also “mouse models”.

The only purpose mouse models serve is to fill the popular press with sensational findings and torture a lot of mice.

For this particular research, it's possible as only 5% of mouse experiments become available to humans.

But a lot of life-saving medicaments and techniques started as mouse testings, including Penicillin, cancer drugs and the polio vaccine.

Is this not the basis of epigenetics? Don’t we already have human-based examples?

While I don’t recall the details there was an example of how starvation (of eventual parents) during WW II impacted the children. There is also, a similar example of how the effects of diet was passed along during The Great Depression.

Earlier quoted context omitted.

Which demographic was casually insulted here? The babies/third children?

Boomers. How can anyone not grasp that? It's as if the insult is like water to fish, so people don't even perceive it.

Is calling someone boomer an insult in itself?

I get that saying “boomer ruined the world for all the generations afterwards” is an insult, but the word itself is now considered an insult?

Genuinely asking here; the constantly shifting landscape of what one is allowed to say when talking to US Americans is a bit hard for me to navigate and I currently only have online discourse as guidepost (which is like 1000% more toxic)
