“That they” (acquired actions) “are inherited, we see with horses in
certain transmitted paces, such as cantering and ambling, which are not
natural to them—in the pointing of young pointers, and the setting of
young setters—in the peculiar manner of flight of certain breeds of the
pigeon, &c. We have analogous cases with mankind in the inheritance of
tricks or unusual gestures.” . . . (“Expression of the Emotions,” p. 29).
In another place Mr. Darwin writes:—
“How again can we explain _the inherited effects_ of the use or disuse of
particular organs? The domesticated duck flies less and walks more than
the wild duck, and its limb bones have become diminished and increased in
a corresponding manner in comparison with those of the wild duck. A
horse is trained to certain paces, and the colt inherits similar
consensual movements. The domesticated rabbit becomes tame from close
confinement; the dog intelligent from associating with man; the retriever
is taught to fetch and carry; and these mental endowments and bodily
powers are all inherited” (“Plants and Animals,” &c., vol. ii. p. 367,
ed. 1875).
“Nothing,” he continues, “in the whole circuit of physiology is more
wonderful. How can the use or disuse of a particular limb, or of the
brain, affect a small aggregate of reproductive cells, seated in a
distant part of the body in such a manner that the being developed from
these cells inherits the character of one or both parents? Even an
imperfect answer to this question would be satisfactory” (“Plants and
Animals,” &c. vol. ii. p. 367, ed. 1875).
With such an imperfect answer will I attempt to satisfy the reader, as to
say that there appears to be that kind of continuity of existence and
sameness of personality, between parents and offspring, which would lead
us to expect that the impressions made upon the parent should be
epitomised in the offspring, when they have been or have become important
enough, through repetition in the history of several so-called existences
to have earned a place in that smaller edition, which is issued from
generation to generation; or, in other words, when they have been made so
deeply, either at one blow or through many, that the offspring can
remember them. In practice we observe this to be the case—so that the
answer lies in the assertion that offspring and parent, being in one
sense but the same individual, there is no great wonder that, in one
sense, the first should remember what had happened to the latter; and
that too, much in the same way as the individual remembers the events in
the earlier history of what he calls his own lifetime, but condensed, and
pruned of detail, and remembered as by one who has had a host of other
matters to attend to in the interim.
