its, species allied to the neighbouring ones, and
not allied to alpine nature as shown in other mountain
summits--even different on different island of similarly
constituted archipelago, not created on two points: never mammifers
created on small isolated island; nor number of organisms adapted
to locality: its power seems influenced or related to the range of
other species wholly distinct of the same genus,--it does not
equally effect, in amount of difference, all the groups of the same
class."
{184} This passage is the ancestor of the concluding words in the
first edition of the _Origin of Species_ which have remained
substantially unchanged throughout subsequent editions, "There is
grandeur in this view of life, with its several powers, having been
originally breathed into a few forms or into one; and that whilst
this planet has gone cycling on according to the fixed law of
gravity, from so simple a beginning endless forms most beautiful
and most wonderful have been, and are being, evolved." In the 2nd
edition "by the Creator" is introduced after "originally breathed."
N.B.--There ought somewhere to be a discussion from Lyell to show that
external conditions do vary, or a note to Lyell's works .
Besides other difficulties in ii. Part, non-acclimatisation of plants.
Difficulty when asked _how_ did white and negro become altered from
common intermediate stock: no facts. We do NOT know that species are
immutable, on the contrary. What arguments against this theory, except
our not perceiving every step, like the erosion of valleys{185}.
{185} Compare the _Origin_, Ed. i. p. 481, vi. p. 659, "The
difficulty is the same as that felt by so many geologists, when
Lyell first insisted that long lines of inland cliffs had been
formed, and great valleys excavated, by the slow action of the
coast-waves."
THE ESSAY OF 1844 PART I
CHAPTER I
ON THE VARIATION OF ORGANIC BEINGS UNDER DOMESTICATION; AND ON THE
PRINCIPLES OF SELECTION
The most favourable conditions for variation seem to be when organic
beings are bred for many generations under domestication{186}: one may
infer this from the simple fact of the vast number of races and breeds
of almost every plant and animal, which has long been domesticated.
Under certain conditions organic beings even during their individual
lives become s
