They're saying something more specific than "urbanisation affects living things" though. The paper tells us 1) that the adaptation has influenced our genetics 2) the approximate timeline (and speed) it took to see that adaptation and 3) that it can be seen across species and across urban centers (in other words, there's an "urbanize" pressure on evolution regardless of if you're in New York City or Delhi). I thought #2 and #3 were surprising, and not necessarily what you would expect.
