This is not '''exactly''' a counter to [[User:Aschlafly|Aschlafly]]. But... Darwin was writing in the days when breeders were starting to do amazing things with selective breeding, which was one of the things that impressed him. Selective breeding is still going on and it is still amazing.  In 1910 the average domesticated chickens laid 80 eggs a year; by 1999 292 eggs a year. There are similar stories for milk production per cow, meat per chicken, etc. Some of the improvement is due to changes in feed, antibiotics, hormones, whatever, but most of it is from selective breeding. So the question I would ask is: if all mutations are harmful, then where do breeders find the slightly improved animals to select as the progenitors of the next generation?
