On Fertile Ground: A natural history of human reproduction by Peter Thorpe
Ellison, Harvard University Press, £19.50, ISBN 0674004639
PETER ELLISON grips your attention from his opening contrast between a
difficult birth in the central Africa that ended in the death of the baby and a
successful delivery in the US that mobilised up-to-date medical facilities.
He isn’t sensationalist. Fascination comes from following the progress from
conception to maturity in minute detail. From the first invasion of an egg cell
by the sperm, the processes relate to human evolution—the defeat of the
female’s immune system, for example. A fertilised egg is a foreign body and
ought to be attacked. It isn’t. Armour, camouflage and artful dodging are all
there.

Later stages of life, such as the steady growth of childhood and the sudden
burst of adolescence, bring Ellison to a wider range, including ecology and
anthropology.
There is a particularly interesting section on body fat—why we have it
and how it is used as emergency food rations. He also explores why we don’t have
much hair, except, he says, a “rather bizarre skullcap”. And, of course, there’s
much about sex.
Now and then you might need a dictionary, but On Fertile Ground is
enjoyable and Ellison has an individual voice.
