It’s stretching it to say epigenetic marks are inherited across multiple generations. The influence weakens quickly.

Non-sleepers of Lemmy, RIP.
Because of the implication?
Reminds me of this one time at Bandwagon…
My husband who disappeared years ago is actually alive and well and conspiring with his friends to downvote my posts and comments. I think he drives by my house from time to time as well.
He is in cahoots with my family, who have custody of my child, to stop my child’s DNA from getting added to a genealogy website because that would prove that he was conceived from incest with a distant relative when I was very young.
Do we have a justunsubbed magazine?
Started it in which time line? There are an infinite number of answers.
I don’t know how to answer your question, but I do have a long unrelated anecdote to share followed by some questions of my own.
And this one.
I thought collagens were components of the extra-cellular matrix.
“The ocean called. They’re running out of shrimp!”
What is it, your period?
You’re not understanding. Without selection, real populations would have changing allele frequencies. They would not stay static. That’s because random sampling exists, but only outside of the H-W model.
Natural selection and evolution happen because genetic traits in some individuals are more beneficial than in other individuals. It has nothing to do with increasing future life expectancy for most or all of the species. If a doctor is helping non-relatives far more than relatives, his contribution is not selected for.
Hardy-Weinberg isn’t appropriate here. If all alleles were neutral, they’d get slowly lost or move toward fixation at a rate proportional to the mutation rate by genetic drift. In the absence of negative selection, new variants that are deleterious without modern medicine would do a random walk in allele frequency, meaning some would become prevalent. But the population is so large they would take far too long to be completely fixed.
Hardy-Weinberg is a model that makes by true assumptions (like zero mutation rate and infinite, isolated populations).
OG Luci is right, though. There are far more people due to modern medicine. So if we suddenly lose it, there will be a lot of death. But there is more population and diversity to draw from the survivors. So I don’t think it’s a threat to the species.

You not only don’t need to hit the meridians, but you also don’t need to penetrate the skin.
What do you call alternative medicine that works? Medicine.
