However, it does suggest technology effecting the evolution of our species. There is also another Theory suggesting we can die of a biological ticking time bomb if we stay on earth too long as well.
There is also a trend that physical attributes doesn't affect mating like it used to. As in, everyone fucks everyone. There is no push for muscle, no push for athleticism. Granted there is some people who want that but not the same push as it was in history. If anything i would guess it would be that, sexual selection and cultural change. Muscle doesn't get you anywhere anymore. it is intelligence, personality, and charisma that bring success now. granted this is only a quick observation.
Evolution isn't affected solely by animals eating other animals. Culture, sexual selection, etc play a part in it. Evolution can never be truly stopped. If sex or reproduction exists, evolution will be there regardless of technology.
