Harmful mutations are usually weeded out by natural selection over time, but the occasional helpful allele can get passed on to future generations.

Yes, weeded out by death.

And the occasional "Helpful" purely random changes just happen to provide some survival benefit for their future generations to be adapted to some future environment. And you call this science?

Zeneta: "Yes, weeded out by death."

Sorry about that.

Science, yes, but not for future generations or environments, rather for immediate benefits.
And in post #62 I mentioned some recent human examples -- high altitude adaptions, different in the Himalayas than in the Andes.
Lactose tolerance among adults in dairying populations.
Cycle-cells to help fight malaria in populations which experience it.

And your problem with this is what, exactly?
