A Quote by Ernst Haeckel

I established the opposite view, that this history of the embryo (ontogeny) must be completed by a second, equally valuable, and closely connected branch of thought - the history of race (phylogeny). Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation... 'ontogenesis is a brief and rapid recapitulation of phylogenesis, determined by the physiological functions of heredity (generation) and adaptation (maintenance).

Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation.

Ernst Haeckel

Phylogeny and ontogeny are, therefore, the two coordinated branches of morphology. Phylogeny is the developmental history [Entwickelungsgeschichte] of the abstract, genealogical individual; ontogeny, on the other hand, is the developmental history of the concrete, morphological individual.

Ernst Haeckel

From the point of view of the pure morphologist the recapitulation theory is an instrument of research enabling him to reconstruct probable lines of descent; from the standpoint of the student of development and heredity the fact of recapitulation is a difficult problem whose solution would perhaps give the key to a true understanding of the real nature of heredity.

E.S. Russell

I shall borrow two words used for a slightly different purpose by the great demographer Alfred Lotka to distinguish between the two systems of heredity enjoyed by man: endosomatic or internal heredity for the ordinary or genetical heredity we have in common with animals; and exosomatic or external heredity for the non-genetic heredity that is peculiarly our own - the heredity that is mediated through tradition, by which I mean the transfer of information through non-genetic channels from one generation to the next.

Peter Medawar

Culture is the most potent method of adaptation that has emerged in the evolutionary history of the living world. - Theodosius Dobzhanksky...the 'facts' of culture history are interpretations based upon assumed culture process.

Jerry Sabloff

At a minimum, in explaining evolutionary pathways through time, the constraints imposed by history rise to equal prominence with the immediate advantages of adaptation.

Stephen Jay Gould

Imitation both unconscious and conscious is par excellence the educational method of the family. It is plain that a considerable part of the adaptation of living beings to their environment, i.e., of beings that are born plastic, is passed on from generation to generation through imitation. Were this not so, much if not all of the road traversed by one generation would have to be travelled by the next generation from the very beginning and without short-cuts. Consequently there would be little chance for the novel adaptation, the propitious individual variation, that constitutes progress.

Elsie Clews Parsons

It is now firmly established that ontogeny does not repeat phylogeny

George Gaylord Simpson

History is one long chain of reflections. Hegel also indicated certain rules that apply for this chain of reflections. Anyone studying history in depth will observe that a thought is usually proposed on the basis of other, previously proposed thoughts. But as soon as one thought is proposed, it will be contradicted by another. A tension arises between these two opposite ways of thinking. But the tension is resolved by the proposal of a third thought which accommodates the best of both points of view. Hegel calls this a dialectic process

Jostein Gaarder

...one doubts existence of free will [because] every action determined by heredity, constitution, example of others or teaching of others." "This view should teach one profound humility, one deserves no credit for anything...nor ought one to blame others.

Charles Darwin

Child psychology and animal psychology are of relatively slight importance, as compared with the sciences which deal with the corresponding physiological problems of ontogeny and phylogeny.

Wilhelm Wundt

People talk about human intelligence as the greatest adaptation in the history of the planet. It is an amazing and marvelous thing, but in evolutionary terms, it is as likely to do us in as to help us along.

Stephen Jay Gould

For me, ancestry is just one thing that connects us to people, and feeling connected to other people is generally a good thing, as long as one kind of connection does not have primacy over all the others. Heredity, race and nationhood are not the best criteria by which to judge our fellow humans.

Jeremy Hardy

Mixture of assimilation to earlier schemas and adaptation to the actual conditions of the situation is what defines motor intelligence. But and this is where rules come into existence as soon as a balance is established between adaptation and assimilation, the course of conduct adopted becomes crystallized and ritualized. New schemas are even established which the child looks for and retains with care, as though they were obligatory or charged with efficacy.

Jean Piaget

Heredity, to our understanding is not capable of giving to this illness (paraphilia) its characteristic form ... Heredity invents nothing, creates nothing anew; it has no imagination.

Alfred Binet

Written history may, in the course of its narrative, use some of the laws established by the various sciences, but its own task remains that of relating the essential sequence of historical action and, qua history, to tell what happened, not why.
