RE: How can we link science to religion?

it just shows how intricate and complex gene regulatory networks are.

I meant multiple independent mutations in the same gene which causes cystic fibrosis. This shows multiple events where the mutation came about and is leading to a negative selection pressure without dying out within a couple of generations like you mentioned it would.

I am not understanding how those stats support your point. People are living longer with cystic fibrosis because of modern treatment techniques not because of a positive evolutionary change to their genome.

Yes with the principles of natural selection there is going to be a increase in the number of people with the cystic fibrosis gene since more are living to reproduce but as a result it leaves their decedents weaker not stronger genetically.
