He also believed that an organisms use or disuse of a bring outicular consistency part would cause it to become large and stronger or smaller and weaker, on an individual basis (Price 1996, 46). Darwin express that the variation is due to the heritability of traits.

He states clearly in The agate line of Species that he does not believe environment to run crosswise a large role in the variability of individuals: Instances could be given of the same variety being produced on a l ower floor conditions of life sentence as d! ifferent as can well be conceived; and, on the another(prenominal) hand, of different varieties being produced from the same species under the same conditions. such(prenominal) facts show how indirectly the conditions of life must(prenominal) act (Darwin 1859, 175).         Darwin did agree with Lamarck that the use or disuse of body parts affected its evolution, but...
