>that we've removed ourselves from so many evolutionary selective pressures. we can't remove ourselves from evolutionary selective pressures. Some old go away, some new come, ie. the nature of such pressures just change, yet the selection continues. And as result there will always be the "fittest" specimen, it will just look and behave differently than the one for the previous version of selective pressures. >the mean of our reproductive ability will drop. with IVF, cloning, etc... that specific selective pressure may go away. On the other side - the ability to make money to pay for the best set of genes would make for nice new selective pressure.
