we, as a species, are doomed. We have been toying with natural selection for decades and have been weakening the gene pool by keeping alive and alowing to prosper, individuals who would normally die. Now that we have the ability to tweak the pool to fix it, but instead, we are compounding our genetic errors...( at least that is true in the first world. It is the third worlders who will take that walk in the sun as they bury us, humankinds mistakes).
Yes. But evolution on the whole isn't necessarily for progressive complexity. The only rule of the game is if it will survive and spread. Or not.
You are so right. Someday everyone will have some degree of diabetes. Before 1929 when insulin was was developed, juvenile diabetics did not generally make it to repoductive age. But....how could we do otherwise than provide insulin?
You're being misled by the MSM here. The existence of a few sickos who are deliberately trying to bear Isabel children means nothing when the vast majority of parents, given improved technology for genetic selection, are trying for children better than themselves: smarter, tougher, less subject to disease.
That used to worry me but it won't be too long before genetic engineering becomes widespread
