Does it, now? How are the hips on that 'perfect' golden retriever? To be more detailed, genes are not single-purpose. The same gene which confers a 'strength' is almost guaranteed to also confer a 'weakness'. Often this weakness is not even evident until an environmental change occurs, at which point the species with the greatest genetic diversity will survive while the one 'optimized' for the prior conditions will die off. Belief in eugenics requires some very particular things, such as, say, physical strength being completely unrelated genetically to metabolic function - which it's not. This doesn't even account for the multitude of things which, if we were to seek to genetically 'optimize' people, we would be inadvertently optimizing or eliminating. Plainly put, eugenics is bad science and a bad idea rooted in ignorance and, most dangerously, a willingness to take shortcuts with scientific rigor that substitute intuition for actual knowledge.
