Is evolution in modern man still going on or will it be suppressed by medicine science and our way of life.

some interesting traits developed in some humans that will sadly not be selected for.

Wim Hof the Iceman, he jogged in shorts in freezing 20 degreez below temperatures us normals would not be able to pull that off, he also holds the record for being submerged in ice for 1 h and 44 minutes we would probably be at a grate risk of death if we tried that and he suffered no ill efects

Daniel Tammet the Brain Man
learned icleandic in 1 weak, knows Pi to the first 22 000 digits

Then you have people with "hercules gens" stronger then us normals and develope muscles faster

Will all of these and other interesting traits be lost because they are not selected for anymore, todays survival depends on making money to feed yourself and if you have bad gens you can get healthcare and pass on your bad gens to the next generation and the good gens have the same amount of chance of being passed on as the bad ones.

First of all, modern medicine is not available to every human being.

Well sometime in the future it will be,

There are also uncurable diseases such as HIV which is actively selecting for CCR-5 mutants. Another way of stating it is that there will always be selective pressures on the human population, it is just a question of which ones.

So what kind of mutation would makeyou have more then 1.9 kids compared to your neighburs 1.9 kids?

I think the larger question is if we will ever take direct control of our own genomes.

As long as there are creos and other fanaticsout there it will be very hard to impliment, sayascan that will test your childs genome while it is still in the womb and treatment for all his will be genetic faults while it is still possible.

For the Iceman, he has trained extensively to withstand these temps. Also, post-natal development can have very large effects on brain function. There is a very large question of how much is due to DNA and how much is due to environment.

I doubt if you train your whole life you would be able to be submerged in ice for 2 hrs.

Re: Selection = Reproduction
Unless you know for sure that these individual examples will not reproduce (have children)?

When i say selected for i mean that these gens will be passed on with the same frequency as say a gen that makes you susceptible to diabetics.

Re: Selection = Reproduction
Why would there be a difference?

In olden days whitout medicine the people with high risk of diabetiswould have alesser chance of passing on this gen because they would diequite often, and people with gens like the ones above would pass on their gens more frequently because their skills would give them a higher status and more women with whom to make babies with
