How? It makes complete sense to me? "Selection pressure" is basically a euphemism, the mechanism of evolution is the differentiation between survivors and those that fucking die. If a lot of evolution is happening, if there's strong pressure and quick changes in response to it, then it means there is a lot of "selecting" going on, a lot of death or at least failure to reproduce which isn't experienced as much less distressing for most organisms.
