I think we are beyond that.
The issue now is that technology is "progressing" instead of human biology "progressing".
This happens 2 ways.
Human biology is actually regressing because normally the majority of random mutations that effect the phenotype are selected against. Technology is greatly reducing all selective forces on biology thus the random negative mutaions are not being eliminated.
And negative reccessive traits that would be selected against over time in a population are not being selcted against as strongly.
Biological evolutionary mechanisms help bring about adaptations in a population, but currently these mechanisms are running without a driver so they bring about random change in a population which is bad.
