model evolution and nature. It wasn’t easy: “Why do theory when Haldane is
sitting in the room next door?”

In the beginning he stuck to fly genetics. But
gradually, with Haldane’s move to India in 1957, John’s confidence had grown.
He was ready to take on evolution on his own.
John hadn’t read Wynne-Edwards’s book before he brought it to Haldane, but
now decided to pay attention. Reviews of the tome had been mixed. Lack, of
course, hated it. So did Wynne-Edwards’s beloved teacher Elton who judged it
“messianic” and “rather wooly.”

Many, however, found the notion of a “balance
of nature” plausible, and, more importantly, deeply relevant to man.
Wynne-Edwards himself egged them along. That summer he had written an
article for Scientific American that began: “In population growth the human
species is conspicuously out of line with the rest of the animal kingdom.”

Man
was virtually alone in showing a long-term upward trend in numbers. It was a
bright red warning sign: However highly he thought of himself, compared to
fulmars and red grouse his social skills were retarded. Modern individual
freedom, alas, had trampled tribal homeostatic wisdom.
Just like Darwin, he was trying to bring animals and man closer together; he had
shown convincingly, an anonymous reviewer in the Times Literary Supplement
wrote, that “social life in man…is no unique affair, but the culmination of a very
widespread biological phenomenon.”

The trouble was that they were drifting
apart. This much, at least, was clear to the anxious reviewer in The Nation:
In Wynne-Edwards’ proofs we can see reflected the breakdown of relations
between parents and children, the male’s and female’s diminished attachment,
the constant migration of peoples, the female’s objection to being just a breeder,
the male’s resentment of being just a provider, smaller families, divorces,
desertions, minorities escaping from “ghettos,” elites struggling to keep out the
invaders, the increase of homosexuality and neuroticism, alcohol and drugs, and
above all, the evidence that young people, the group most sensitive to social
stress, desire violence, especially if it is unprofitable and senseless: in all this we
see that human society is reacting just as Wynne-Edwards says a crowded society
should. It is giving a warning which nobody heeds; even when they see the Sunday
cars jamming the highways, as in a dance of gnats, or a swarming of locusts.

Maynard Smith took a cool look at the data. Despite the vogue of
population-explosion hysteria there was no need to get excited. Theoretically,
though, if group selection worked, short of decreasing homosexuality and
clearing up traffic jams, it could be an important mechanism in evolution.
He himself had been contemplating the phenomenon of aging. Why, for heaven’s
sake, would evolution select for the degrading of the body: Wouldn’t it be better
to be able to reproduce indefinitely? The nineteenth-century giant August
Weismann had considered the conundrum and thought the answer lay with the
collective: Evolution pushed individuals into old age to make room for the next
