The Foundations of the Origin of Species: Two Essays written in 1842 and 1844
Darwin, Charles
Evolution (Biology); Natural selection
by his own direct foresight or by intermediate means,--which will
represent <?> the creator of this universe. Seems usual means. Be it
remembered I have nothing to say about life and mind and _all_ forms
descending from one common type{53}. I speak of the variation of the
existing great divisions of the organised kingdom, how far I would go,
hereafter to be seen.
{50} The author may possibly have taken the case of the woodpecker
from Buffon, _Histoire Nat. des Oiseaux_, T. vii. p. 3, 1780, where
however it is treated from a different point of view. He uses it
more than once, see for instance _Origin_, Ed. i. pp. 3, 60, 184,
vi. pp. 3, 76, 220. The passage in the text corresponds with a
discussion on the woodpecker and the mistletoe in _Origin_, Ed. i.
p. 3, vi. p. 3.
{51} This illustration occurs in the _Origin_, Ed. i. pp. 90, 91,
vi. pp. 110, 111.
{52} See _Origin_, Ed. i. p. 83, vi. p. 102, where the word
_Creator_ is replaced by _Nature_.
{53} Note in the original. "Good place to introduce, saying reasons
hereafter to be given, how far I extend theory, say to all
mammalia--reasons growing weaker and weaker."
Before considering whether <there> be any natural means of selection, and
secondly (which forms the 2nd Part of this sketch) the far more
important point whether the characters and relations of animated
<things> are such as favour the idea of wild species being races <?>
descended from a common stock, as the varieties of potato or dahlia or
cattle having so descended, let us consider probable character of
[selected races] wild varieties.
_Natural Selection._ De Candolle's war of nature,--seeing contented face
of nature,--may be well at first doubted; we see it on borders of
perpetual cold{54}. But considering the enormous geometrical power of
increase in every organism and as <?> every country, in ordinary cases
<countries> must be stocked to full extent, reflection will show that
this is the case. Malthus on man,--in animals no moral [check] restraint
<?>--they breed in time of year when provision most abundant, or season
most favourable, every country has its seasons,--calculate
robins,--oscillating from years of destruction{55}. If proof were wanted
let any singular change of climate <occur> here <?>, how astoundingly
some tribes <?> increase, also introduced animals{56}, the pressure is
always ready,--capacity of alpine plants to endure other
climates,--think of endless seeds scattered abroad,--forests regaining
their percentage{57},--a thousand wedges{58} are being forced into the
oeconomy of nature. This requires much reflection; study Malthus and
calculate rates of increase and remember the resistance,--only
periodical.
{54} See _Origin_, Ed. i. pp. 62, 63, vi. p. 77, where similar
reference is made to De Candolle; for Malthus see _Origin_, p. 5.
