Evolutionary Purpose Quotes

I have an odd theory on happiness, and it bothers people. My general theory is that happiness is a reward for an animal doing what it should be doing. So if a horse runs, it feels happy. Or if you are too thin, you can't be happy, because evolution wants you to be tense and anxious, trying to wake up in the morning looking for food.

No species ... possesses a purpose beyond the imperatives created by genetic history ... The human mind is a device for survival and reproduction, and reason is just one of its various techniques.

Leaving the complications of the human breakfast-table out of account, in an elemental sense, the egg only exists to produce the chicken. But the chicken does not exist only in order to produce another egg. He may also exist to amuse himself, to praise God, and even to suggest ideas to a French dramatist. Being a conscious life, he is, or may be, valuable in himself.

Why, for example, should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organise themselves into a professor of chemistry? What's the motive?

Human beings are ultimately nothing but carriers-passageways- for genes. They ride us into the ground like racehorses from generation to generation. Genes don't think about what constitutes good or evil. They don't care whether we are happy or unhappy. We're just means to an end for them. The only thing they think about is what is most efficient for them.

Why do we have a brain in the first place? Not to write books, articles, or plays; not to do science or play music. Brains develop because they are an expedient way of managing life in a body.

The cost of scientific advance is the humbling recognition that reality was not constructed to be easily grasped by the human mind. This is the cardinal tenet of scientific understanding. Our species and its ways of thinking are a product of evolution, not the purpose of evolution.

Love is only a dirty trick played on us to achieve continuation of the species.

Man has risen, not fallen. He can choose to develop his capacities as the highest animal and to try to rise still farther, or he can choose otherwise. The choice is his responsibility, and his alone. There is no automatism that will carry him upward without choice or effort and there is no trend solely in the right direction. Evolution has no purpose; man must supply this for himself. The means to gaining right ends involve both organic evolution and human evolution, but human choice as to what are the right ends must be based on human evolution.

By shrewdly linking procreation to an act likely to make you stupid with excitement, God has seen to it that Life does indeed go on. It's possible, by the way, that this is why God's name comes up so often in the middle of the act; it's a salute to the author: Hey, whoever made this up - thanks.

For me, the meaning of life is pretty clear: Living things strive to pass their genes into the future.

The meaning of life is pretty clear: Living things strive to pass their genes into the future. The claim that we would not have morals or ethics without religion is extraordinary. Animals in nature seem to behave in moral ways without organized religion.

U.K. psychologist Daniel Nettle thinks of happiness as a carrot on a stick, designed by evolution to show the right way, and also designed so that we will never permanently reach it. We likely would just sit around and eat sweet and fatty foods all day, and that is simply not in the interest of evolution.

A selfish basis would not serve the purpose of taking a man higher and higher along the paths of evolution.

The mission of DNA is to evolve nervous systems capable of deciphering the mission of DNA.

Though why should we expect age to mellow us? If it isn't life's business to reward merit, why should it be life's business to give us warm comfortable feelings towards its end? What possible evolutionary purpose could nostalgia serve?

When I say that human beings are just gene machines, one shouldn't put too much emphasis on the word 'just.' There is a very great deal of complication, and indeed beauty in being a gene machine.

Sexually,Woman is Nature's contrivance for perpetuating its highest achievement.

This last chapter .. may have given the impression that somehow man is the ultimate triumph of evolution, that all these millions of years of development have had no purpose other than to put him on earth. There is no scientific evidence whatever to support such a view and no reason to suppose that our stay here will be any more permanent than that of the dinosaur.

In the frantic search for an elusive 'cure,' few researchers stand back and ask a very basic question: why does cancer exist? What is its place in the grand story of life?

You're right, a spleen is a strange thing-we technically don't need one, but maybe spleens are kept in our bodies in case we mutate or evolve, and if we grow wings or tentacles we need to have the spleen in place in order for them to work.

While language can surely be used for communication (as can much else), communication probably has no special role in its design or evolution.

Happiness is just another of the tricks that our genetic system plays on us to carry out its only role, which is the survival of the species.

We want to be special. We want our place in the cosmos to be central. We want evolution-even godless evolution-to have been directed toward us so that we stand at the pinnacle of nature's ladder of progress. Rewind the tape of life and we want to believe that we (Homo Sapiens) would appear again and again. Would we? Probably not.
