The major flaw with this theory is that it's his definition of what Attractive is.
Everyone has a different opinion on what makes an attractive partner...
Therefore I severely doubt that all future humans will be 7 Ft tall.
As a lot of people don't find excessive height an attractive feature, regardless of what the modeling industry thinks.
I do believe that the lines between Blacks/Whites/Asians will blur considerably... however I also believe that the same will happen with 'ugly' and
'pretty' people,
Also Biology isn't terribly interested in what looks good, it's more interested in staying alive in its surrounding environment. For women to
develop completely hairless bodies would be impractical, as their skin would have no temperature regulation. Also 'pert breasts' is another opinion
of his. As we all know different guys like different kind of boobs.
The Scientist is assuming that everyone follows the same pattern of what is attractive and unattractive.
