Human Hyper Evolution

The super powers of the X-Men may still may take awhile in the evolutionary process. However scientists have discovered that due to rapid population growth human evolution may be speeding up.
In a fascinating discovery that counters a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts.

Thanks to stunning advances in sequencing and deciphering DNA in recent years, scientists had begun uncovering, one by one, genes that boost evolutionary fitness. These variants, which emerged after the Stone Age, seemed to help populations better combat infectious organisms, survive frigid temperatures, or otherwise adapt to local conditions.

Hmm. It seems to me that in many ways civilization tends to reduce individual fitness. For just one example, the availability of orthodontics allows children with bad teeth to (in effect) hide that fact, get married and have children with bad teeth.

Also, I would think that in a larger community it would take longer for a given genetic change to propagate from one person to the rest of the community, unless it is classically dominant. So there would be little visible effect for many generations. But then it might show up among a larger fraction of the population rapidly once the probabilities of two parents both having the gene achieve a sufficient level. If it's a 'good' change, then all is well. But if it's a 'bad' change, then it could cause a large scale problem.
