According to the concept of transformational evolution, first clearly articulated by Lamarck, evolution consists of the gradual transformation of organisms from one condition of existence to another.
Ernst Mayr

Darwin based his theory on generalizations that were strictly empirical. You can go out and see that organisms do vary, that variations are inherited, and that every organism is capable of increasing its numbers in sufficiently favorable circumstances.
George C. Williams

Each organism, no matter how simple or complex, has around it a sacred bubble of space, a bit of mobile territoriality which only a few other organisms are allowed to penetrate and then only for short periods of time.
Edward Hall

Each organism's environment, for the most part, consists of other organisms.
Kevin Kelly

Evolutionary biologists are not content merely to explain how variation occurs within limits, however. They aspire to answer a much broader question-which is how complex organisms like birds, and flowers, and human beings came into existence in the first place.
Phillip E. Johnson

First, Darwinian theory tells us how a certain amount of diversity in life forms can develop once we have various types of complex living organisms already in existence.
Phillip E. Johnson

If our society continues to support basic research on how living organisms function, it is likely that my great grandchildren will be spared the agony of losing family members to most types of cancer.
Paul D. Boyer

If you want to study one of these strange organisms, you had better have a good justification. It's not good to study gene organisation in some obscure insect that no one's ever heard about.
Thomas R. Cech

It has become evident that the primary lesson of the study of evolution is that all evolution is coevolution: every organism is evolving in tandem with the organisms around it.
Kevin Kelly

Let's talk of a system that transforms all the social organisms into a work of art, in which the entire process of work is included... something in which the principle of production and consumption takes on a form of quality. It's a Gigantic project.
Joseph Beuys

Man, like other organisms, is so perfectly coordinated that he may easily forget, whether awake or asleep, that he is a colony of cells in action, and that it is the cells which achieve, through him, what he has the illusion of accomplishing himself.
Albert Claude

Nature favors those organisms which leave the environment in better shape for their progeny to survive.
James Lovelock

Next it was found that it was physiologically and structurally the same in the plant, that it was the living part of the plant, that which manifested the life and did the work in vegetable as well as in animal organisms.
Asa Gray

One of the deepest functions of a living organisms is to look ahead... to produce future.
Francois Jacob

Organisms by their design are not made to adapt too far.
Kevin Kelly

Owing to the difficulty of dealing with substances of high molecular weight we are still a long way from having determined the chemical characteristics and the constitution of proteins, which are regarded as the principal con-stituents of living organisms.
Karl Landsteiner

People are not the only interesting organism on earth. From the point of view of scientific or commercial value, there are lots of interesting organisms.
Daniel Nathans

Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.
George G. Simpson

The investigation into the possible effects of cosmic rays on living organisms will also offer great interest.
Victor Francis Hess

The position I took at the time was that we hadn't really examined any of the potential environmental consequences of introducing genetically modified organisms.
Jeremy Rifkin
