THE MANUSCRIPT OF A KEY SECTION IN DARWIN'S FINAL EVOLUTIONARY WORK, IN WHICH HE WRITES DIRECTLY ABOUT EVOLUTIONARY PROCESSES. This section of text is found in revised form on p.48 of the first edition of The Expression of the Emotions in Man and Animals. It comes at the conclusion of the chapter at the end of Darwin's discussion of what he terms "Associated habitual movements in the lower animals". These are habitual actions that have long-since lost any practical function, such as a domestic dog turning round before settling to sleep as if to scoop out a hollow, or a tame Shelduck patting the ground with its feet when asking for food, as its wild cousin would do over a worm-cast. Darwin's argument here is noteworthy as he suggests that learned behaviours can become heritable through repetition. Darwin had ignored this Lamarckian theory of evolution in the Origin, and it has since been proved to be baseless, but it was part of his argument in several of his later works.
