Ours is, or was, a man's world. But biologically speaking, male supremacy
hangs by a thread.
In half-playful dread, a zoologist looks at what men have to fear from the
march of evolution.
Imagine a white, middle-class, western couple about to pick the sex of their
next child (this choice will soon no longer be a fantasy). If they are rational
and thorough people, never in a 1,000 years would they choose a boy. Not only
is ours more and more a woman's world; by the second quarter of the 21st
century, when a child born now will be mature, it will be time to wonder if men
have a future.In many areas of life they will be marginal, in others an
expensive unisance.
If that sounds wild or overdone, consider the more galring weaknesses in the
so-called stronger sex. Start with medical ones. Boys are more often born with
inherited diseases. Because they do not have a spare x-chromosome, whereas
girls do , boys with a faulty gene have no back-up. The effects of this
deficiency can range from colour-blindness to haemophilia.
太好了......
