This is why evolution is so interesting. The span of time that man has walked erect is relatively small in the scale. The doubling of man's life expectancy is relatively nano scale. Hence... Back problems in old age that evolution has just not had time to "correct" for.
Same with ear flaps. And damaging noise is an even worse case for us. In millions of years of evolution damaging levels of noise exposure were all but non existant. Certainly never sufficient to cull susceptibility, inability to recover or oversensitivity, from the 'herd'. Hell, noise exposure levels only changed for the worse for humans in half a dozen generations or so. Thats a grain of sand's scale on a beach.
If it were imaginable that humans might evolve another few million years, in present conditions (i'll pause here a moment for the laughter to die down), we'd see something very much like the ear flaps described, or some more robust drum anvil stirrup cochlea that enables older men and women to weather high noise exposure, still hear each other sufficient to court and find one another still attractive....and keep on fucking.
