Question:  Has evolution in the human species been stopped by modern medicine?

Question:  Has evolution in the human species been stopped by modern medicine?

Evolution is the process whereby the environment prevents certain individuals of a population from successfully breeding. It must be understood that the members of the sub-population all shared a genetically determined trait, upon which nature acted.

So, rewording your question in terms of the definition of evolution:

Has modern medicine prevented the environment from preventing some human individuals from successfully breeding?




I think that you'd have to consider the entire population of Earth in considering the answer.


sorta like:


Is nature still capable of preventing some genetic sub-population of humans from mating successfully despite the advent of modern medicine?


What do you think?

It's interesting to note that sapiens shared the planet with the other human species for about 30,000-40,000 years before the other species "became extinguished."

I guess I was thinking along the lines of sub populations that now breed that say 300 years ago would not have bred.  For instance, there are people who(m?) smallpox is not fatal. By eradicating for the most part, smallpox, have we ended up with a weaker species in comparison to a species that is genetically resistant to small pox?  I guess this goes with other diseases that have high fatality rates.

Just opinion seeking.  The question popped into my mind reading about the "germ warfare" waged against the Plains Indians.

Upon reflecting, I think the verb "prevent" may be too strong. Perhaps "severely limit the odds of" may be better.

I think that PJ and Mball should be consulted.

My question is whether surviving a small pox infection is the result of genetics.

Amazingly, the array of B- and T-cells that are produced in an individual's bursa, is a random lot, and changes over time.

I haven't seen a study, but I'd like to compare the detailed array of lymphocytes between identical twins. Also, are there cases where one of an infected pair of twins died, whereas the other survived. That's the kind of data I'd like.

Those are the type questions and studies that I was looking for.  It also brings to mind "carriers" like Typhoid Mary.  Has a genetic marker been found for carriers?

Questions just lead to more questions.  It will keep me occupied some evening(s) and then I'll lose interest.


Or the grand query, does the superhuman await mankind in the future or do the viruses win before that?

Get a Ph.D., a tenured faculty position, a lab full of techs and grad students, and a few big grants that expire in two years. That'll prevent the losing of the interest.

A fine article on the role of fossil fuels and our industrial world.

Why does it have you listed as a guest here, FnL?

Also, you need to put your av back up. They were all reset during Fog’s tinkering.

Gonna go back to the chocolate chick? Maybe Eric Burdon or Jack Bruce?
