| I don't think any of you understand genetics. It is true that letting people with "bad" genes survive lets them reproduce and spread their genes. However, the actual frequency of the "bad" allele will not increase beyond that. Letting "bad" alleles spread does NOT inhibit the spread of "good" ones. Absent further selection, disease-protecting genes that evolved in the face of eliminated diseases will still have the same prominence in the population that they did when the disease was a great killer. This might sound slightly counterintuitive, but it is true. If 5% of the population needs to take medicine for bad genes, the same 5% will need to take it in 1000 years, not 100%. |
