memory from those of the individual."

Again:-

"Another point which we have here to consider is the part which
heredity has played in forming the perceptive faculty of the
individual prior to its own experience. We have already seen that
heredity plays an important part in forming memory of ancestral
experiences, and thus it is that many animals come into the world
with their power of perception already largely developed. The
wealth of ready-formed information, and therefore of ready-made
powers of perception, with which many newly-born or newly-hatched
animals are provided, is so great and so precise that it scarcely
requires to be supplemented by the subsequent experience of the
individual." {53a}

Again:-

"Instincts probably owe their origin and development to one or other
of the two principles.

"I. The first mode of origin consists in natural selection or
survival of the fittest, continuously preserving actions, &c. &c.

"II. The second mode of origin is as follows:- By the effects of
habit in successive generations, actions which were originally
intelligent become as it were stereotyped into permanent instincts.
Just as in the lifetime of the individual adjustive actions which
were originally intelligent may by frequent repetition become
automatic, so in the lifetime of species actions originally
