Few if any of the domestic animals (dogs, cats, horses, cows, pigs, sheep, chickens etc etc) or domestic plants (eg most crops, garden flowers etc) would exist in anything like their current forms if humans had not bred them to it.
And, while humans may not be doing much in the way of deliberately altering themselves yet, we've already been considerably changed because we're a social animal. And we're still in the middle of it - the fact that humans are so prone to circulatory problems, back problems, hernia problems etc is because we're still adapting to being bipeds.
Our society and technology are changing us whether we want it or not. So, if it's going to happen to us anyway, why not try to direct it to some extent?
And, since it's something that people are going to start doing anyway, it would be wise to start developing ways to deal with it rather than deluding ourselves that it can't happen here.
