Domestic duck versus wild-duck. Avian Darwin.

Domestic duck versus wild-duck. Avian Darwin. 


“With animals the increased use or disuse of parts has had a more marked influence; thus, I find in the domestic duck that the bones of the wing weigh less and the bones of the leg more, in proportion to the whole skeleton, than do the same bones in the wild-duck; and this change may be safely attributed to the domestic duck flying much less, and walking more, than its wild parents.”

Charles Darwin

Origin of Species; 1873.

Chapter 1, page 8, Variation under Domestication.

First edition in which Darwin uses the word evolution. This was also the last edition published during Darwin's lifetime.
