have been requested to ... recommend a naturalist to go as companion to
Captain Fitzroy, who has been commissioned by the government to survey
the southern coasts of South America. I have stated that I consider you to be
the best qualified person I know of who is likely to undertake such a situation.
As far as the financial side of it is concerned, I have no notion. The voyage is
to last two years ... ‘ “
“How can you remember all that by heart?”
“A bagatelle, Sophie.”
“And what did he answer?”
“He wished ardently to grasp the chance, but in those days young men
did nothing without their parents’ consent. After much persuasion, his father
finally agreed— and it was he who financed his son’s voyage. As far as the
‘financial side’ went, it was conspicuous by its absence.”
“Oh.”
“The ship was the naval vessel HMS Beagle. It sailed from Plymouth on
December 27, 1831, bound for South America, and it did not return until
October of 1836. The two years became five and the voyage to South
America turned into a voyage round the world. And now we come to one of
the most important voyages of discovery in recent times.”
“They sailed all the way round the world?”
“Yes, quite literally. From South America they sailed on across the
Pacific to New Zealand, Australia, and South Africa. Then they sailed back to
South America before setting sail for England. Darwin wrote that the voyage
on board the Beagle was without doubt the most significant event in his life.”
“It couldn’t have been easy to be a naturalist at sea.”
“For the first years, the Beagle sailed up and down the coast of South
America. This gave Darwin plenty of opportunity to familiarize himself with the
continent, also inland. The expedition’s many forays into the Galapagos
Islands in the Pacific west of South America were of decisive significance as
well. He was able to collect and send to England vast amounts of material.
However, he kept his reflections on nature and the evolution of life to himself.
When he returned home at the age of twenty-seven, he found himself
renowned as a scientist. At that point he had an inwardly clear picture of what
was to become his theory of evolution. But he did not publish his main work
until many years after his return, for Darwin was a cautious man—as is fitting
for a scientist.”
“What was his main work?”
“Well, there were several, actually. But the book-which gave rise to the
most heated debate in England was The Origin of Species, published in 1859.
Its full title was On the Origin of Species by Means of Natural Selection, or the
Preservation of Favoured Races in the Struggle for Life. The long title is
actually a complete resume of Darwin’s theory.”
“He certainly packed a lot into one title.”
“But let’s take it piece by piece. In The Origin of Species, Darwin
advanced two theories or main theses: first, he proposed that all existing
vegetable and animal forms were descended from earlier, more primitive
forms by way of a biological evolution. Secondly, that evolution was the result
of natural selection.”
“The survival of the fittest, right?”
“That’s right, but let us first concentrate on the idea of evolution. This, in
