When on board H.M.S. 'Beagle,' as a naturalist, I
was much struck with certain facts in the distribution of the inhabitants of South
America, and in the geological relations of the present to the past inhabitants
of that continent. These facts seemed to me to throw some light on
the origin of species -- that mystery of mysteries, as it has been called
by one of our greatest philosophers [John Frederick William Herschel (1792-1871)].
On my return home, it occurred to me, in 1837, that something might
perhaps be made out on this question by patiently accumulating and reflecting
on all sorts of facts which could possibly have any bearing on it.
