Frozen Evolution. Or, that’s not the way it is, Mr. Darwin. A Farewell to Selfish Gene.

This model of evolution assumes that the adaptive traits of modern organisms are formed in that the members of a certain species begin to devote themselves to certain activities, for example, they reach the tops of trees for leaves, in this “exercise” they lengthen their necks and their offspring then inherit these prolonged necks. It cannot now be determined whether Lamarck really had such a naïve idea, he did not state things so explicitly in his work “Philosophia Zoologica”. That is, however, not important today – Lamarckism is now understood as the formation of adaptive traits through the relevant “exercising” and subsequent inheritance of these acquired properties.
