In 2009 we celebrated
the 200th
anniversary of Darwin’s birth. We
also celebrated the 150th anniversary
of the publication of his most
famous book, On the Origin of
Species. Indeed, if you were to ask
most people about Darwin and
what he wrote, the only work
they’re likely to remember is the
Origin — with good reason. It was
the Origin, after all, in which
Darwin laid out the evidence for
descent with modification and for
evolution by natural selection. If you
pressed, some people might remember
the Voyage of the Beagle or,
maybe, theDescent of Man, but you
are unlikely to get much further.
Steve Jones wants readers to
remember that there were many
other books as well, from On the
Various Contrivances by which
Orchids are Fertilized by Insects
to On the Formation of Vegetable
Mould through the Action of
Worms. And he wants them to
remember that these books draw
largely on original observations he
made on plants and animals in “the
garden of England” referred to in
the subtitle. He wants to convince
you that “[t]he great naturalist’s
lifelong labours generated an archipelago
of information; a set of connected
observations that together
form a harmonious whole.”
He succeeds. For there is a constant
thread running through
Darwin’s work. Even when Darwin
is writing about the Power of
Movement in Plants, the thread of
common ancestry is never far from
the surface. Darwin couldn’t have
known that the signal proteins
allowing a sensitive plant (Mimosa
pudica) to respond to touch are
related to signal proteins in the
human body promoting the production
of certain hormones, but
even so Darwin couldn’t stop himself
from writing that “[i]t is impossible
not to be struck with the
resemblance between the foregoing
movements of plants and many
of the actions performed unconsciously
by the lower animals.”
But Jones’s object is not merely
to describe what Darwin wrote.
Rather, he uses each of Darwin’s
books as a springboard to introduce
readers to a wide range of
discoveries in modern biology,
from signaling proteins to DNA
paternity testing to homeobox
genes, and to show how this vast
diversity can all be understood as a
consequence of the two fundamental
processes Darwin identified:
descent with modification
and evolution by natural selection.
The book is not perfect. In discussing
The Effects of Cross- and
Self-Fertilization in the Vegetable
Kingdom, Jones first argues that the
death of Darwin’s first daughter,
Annie, “may … in part have been
due to her parents’ marital history”
(Charles and Emma Darwin were
first cousins), though the immediate
cause was tuberculosis. A few
pages later he writes that “[t]he
great man’s concern about the possible
damage to his own children
was not justified.” Small contradictions
like this may be difficult to
avoid when telling an engaging
story, but they are distracting.
As Jones points out, Darwin
wrote to Huxley a few years after
publication of the Origin that “I
sometimes think that general and
popular Treatises are almost as
important for the progress of science
as original work.” Chris
Mooney and Sheril Kirshenbaum,
in Unscientific America, and
Randy Olson, in Don’t Be Such a
Scientist, have made similar pleas,
and science would benefit if more
of us paid attention — as Steve
Jones has done for more than two
decades. Already a popular author
and commentator in Great Britain,
in Darwin’s Island he introduces a
wide audience to Darwin’s other
books, books that specialists know
well but that few others even realize
exist. In doing so he reminds us
all of the great fabric that is modern
biology and of its warp and
weft, which is evolutionary theory.
