No, but you have to hunt mates if you wish to spawn. Tall
seems to be preferred by modern humans. It doesn't need
to have a purpose. Mate selection is shaping our species
much more quickly and thoroughly than differential survival.
We also seem to be selecting thinner mates, all the better to
survive in a horrifically calorie-rich environment, perhaps.
Another mechanism I thought of today is the availability of
C-section births in modern times has allowed the survival of
mothers of infants whose heads would be too large for
vaginal delivery. This may account for *some* of the
embiggening of our species.
I think the old hormones in milk is a pretty good explanation,
along with steroids and hormones for athletic development.

Ja, so why not an *unnatural* step?

No. Please stand by. The singularity will serve you momentarily.
