Heredity Quotes
For the fundamental fact of human psychology is that society, instead of remaining almost entirely inside the individual organism as in the case of animals prompted by their instincts, becomes crystallized almost entirely outside the individuals. In other words, social rules, as Durkheim has so powerfully shown, whether they be linguistic, moral, religious, or legal, etc., cannot be constituted, transmitted or preserved by means of an internal biological heredity, but only through the external pressure exercised by individuals upon each other.
Jean Piaget
No work which is destined to become a classic can look like the classics which have preceded it. In art, as in biology, there is heredity but no identity with the ascendants. Painters inherit characteristics acquired by their forerunners; that is why no important work of art can belong to any period but its own, to the very moment of its creation. It is necessarily dated by its own appearance. The conscious will of the painter cannot intervene.
Juan Gris
All life on earth - everything from bacteria to mushrooms to hippos - shares an astonishing range of detailed biochemical similarities, including the structure of heredity in DNA and RNA, and the universal use of ATP as an energy-storing compound. Two possible scenarios, with markedly different implications for the nature of life, might explain these regularities: either all earthly life shares these features because no other chemistry can work, or these similarities only record the common descent of all organisms on earth from a single origin that happened to feature this chemistry as one possibility among many.
Stephen Jay Gould
I do not claim that intelligence, however defined, has no genetic basis-I regard it as trivially true, uninteresting, and unimportant that it does. The expression of any trait represents a complex interaction of heredity and environment. [... A] specific claim purporting to demonstrate a mean genetic deficiency in the intelligence of American blacks rests upon no new facts whatever and can cite no valid data in its support. It is just as likely that blacks have a genetic advantage over whites. And, either way, it doesn't matter a damn. An individual can't be judged by his group mean.
Stephen Jay Gould
In fact, for a voluntarist like Schopenhauer, a theory so sanely and cautiously empirical and rational as that of Darwin, left out of account the inward force, the essential motive, of evolution. For what is, in effect, the hidden force, the ultimate agent, which impels organisms to perpetuate themselves and to fight for their persistence and propagation? Selection, adaptation, heredity, these are only external conditions. This inner, essential force has been called will on the supposition that there exists also in other beings that which we feel in ourselves as a feeling of will, the impulse to be everything, to be others as well as ourselves yet without ceasing to be what we are.
Miguel de Unamuno
As these lines are being written, the circumstances under which I first clearly grasped the important generalisation that the laws of Heredity were solely concerned with deviations expressed in statistical units, are vividly recalled to my memory. It was in the grounds of Naworth Castle, where an invitation had been given to ramble freely. A temporary shower drove me to seek refuge in a reddish recess in the rock by the side of the pathway. There the idea flashed across me, and I forgot everything else for a moment in my great delight.
Francis Galton
The Head of the State in the British Constitution is a Monarch and the Crown descends according to the rules of heredity. In India the Head of the State is an elected President who holds office for a term and can be removed for misconduct in accordance with the procedure laid down in the Constitution.

Heredity is to-day the central problem of biology. This problem may be approached from many sides - that of the breeder, the experimenter, the statistician, the physiologist, the embryologist, the cytologist - but the mechanism of heredity can be studied best by the investigation of the germ cells and their development.

"I should not care to be married for my money," said Lucie. "Oh, strange creature!" said the doctor, "you would like to be loved for your face alone, that is to say, for the position in space of the albuminoids and fatty molecules placed there by the working of some Mendelian heredity, but you would dislike to be loved for your fortune, to which you have contributed by your labor and your domestic virtues.
André Maurois
Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.
Lynn Margulis
I have always been interested in family history. Chromosomes are funny things, aren't they? They may skip a generation and you can find children who resemble the grandfather, rather than either parent. Heredity is more important than environment. Blood will tell. For example, a man is either musical by heredity or he is not. You can't make a man musical by the environment. You can find a person who is very musically inclined and be puzzled because neither parents nor grandparents had any ear for music. But if you trace it back, you will find that the great-grandfather was a musician. But the environment plays a great part in the development of a man. It is significant whether a man is brought up in the city or in the country, near a lake or on the shores of the ocean.
Hermann Göring
Eugenics should, therefore, not be allowed to deceive us into the belief that we should try to raise a race of supermen, nor that it should be our aim to eliminate all suffering and pain. The attempt to suppress those defective classes whose deficiencies can be proved by rigid methods to be due to hereditary causes, and to prevent unions that will unavoidably lead to the birth of disease-stricken progeny, is the proper field of eugenics. How much can be and should be attempted in this field depends upon the results of careful studies of the law of heredity. Eugenics is not a panacea that will cure human ills, it is rather a dangerous sword that may turn its edge against those who rely on its strength.
