Sorry, but if individuals do NOT evolve, then there's no way in hell populations of them will!
Wow. That's actually THE most irrational thing I've ever seen said on one of these threads, and that's saying something.
Imagine a colony of bacteria. There are one million bacteria in the colony and 10000 of them (1%) are antibiotic resistant. Now you treat the colony with an antibiotic. Let's say 90% of the non-resistant bacteria die and 10% of the resistant ones do. Now you have 99000 non resistant bacteria left and 9000 resistant ones. The frequency of the allele for antibiotic resistance has gone from 1% to 8.3%. That is a change of allele frequencies in the gene pool of a population. Evolution has occurred. No organism in the population has changed, but the population as a whole has.
