Calluses and blisters can be a very appropriate illustration
how known external actions give rise to surface
the tissue is very remarkable phenomena, which, however, do neither
the needs of the body, nor to its normal structure. This is the essence of such
changes that do not lead to adaptation, either to improve
the type. Noting them, we can move on to related, but more
instructive changes. Continuous pressure on any part
surface causes atrophy, while intermittent pressure causes
growth: one delays the circulation and transfer blood from the capillaries into tissue, and
other contributes to both. There are further encountered
by mechanical effects. We have some evidence that the nature of the
calloused skin on the bottom of the legs and on the inner side of arms
caused by friction and alternating pressure: first, the most
subjected to rough impact, be the most hardened;
second, the inner surface of the arms exposed to very often rude
drink, as sailors, absolutely become very
corny on the surface, and, third, hands that are very small
used in the work, usually hardened part becomes quite
soft. Anyway, like it or fully Express the idea of these different
proof, I only prepare the way for a much more convincing.

"In many cases, there is reason to think that reduced use of
different bodies have influenced the relevant parts of the body of the offspring.
But there is no good evidence that this ever occurred during the
one generation... Our domestic chickens, geese and ducks almost completely
lost not only of individuals but of the entire breed the ability to fly;
and because we never happen to see a scared chicken trying
would fly off as does a young pheasant... Have a pigeon chest length
bones, the height of its crest, the length of the blade and darling, the length of the wings measured
between the ends of the radial bone, all become smaller compared to
relevant parts of the wild pigeon". After a similar and detailed
consideration of reducing the size of chickens and ducks, Darwin adds:
"The reduced weight and size of bones in the previous cases, in all probability,
is an indirect result of the reaction of the weakened muscles on the bones...
Patasius showed that reduced pig breeds in the shortness of the legs and the snout
form articular processes of the head and the position of the upper jaws with fangs
outstanding very the wrong way forward from the lower canines can be
attributed to the fact that these units were not sufficient exercise... So
the changes in the structure, the well-inherited, characterise
some superior breed because they could not occur from any
home or a wild race. Relative to cattle, Professor Tanner
noticed that lungs and liver in the improved breeds are much
less in volume compared to the same parts in animals using
sovershennoe freedom... the Reason for the decrease lungs vysokoorganizovannym
species of animals who make little movement, is obvious of itself". (On
the following pages Darwin also cites facts that illustrate the consequences
the use or disuse in the change of the ears, the length of the intestinal
channel and nature of the instincts animals.)
However, the assumption, or rather assertion of Darwin, that the transmission
the inheritance of functional changes occurred is a factor in organic
evolution becomes especially apparent not one of those passages that
cited by us above. Much better it turns out it is from one place to
the Preface to the second edition of his "descent of man". He's there
protests against the widespread distortions of its views that
the above mentioned factor is not manifested in nature.
