I don't know what reason there is to think we have slowed
evolution, rather than speeded it up.

I would hazard to guess, for example, that since the discovery of 
birth control, we have been selecting very rapidly for people who 
choose to have more babies. In fact, I suspect this is one reason
why the US (which became rich before most of the rest of the world)
has a higher birth rate than Europe.

Likewise, I expect medical advances in childbirth etc are selecting
very rapidly for multiple births (which once upon a time often killed 
off mother and child.) I expect this, rather than or in addition to
the effects of fertility drugs, is the reason for the rise in 
multiple births.

etc.
