A Quote by Richard Dawkins

For me, the level at which natural selection causes the phenomenon of adaptation is the level of the replicator - the gene.

Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level.

E. O. Wilson

Group selection and individual selection are just two of the selection processes that have played important roles in evolution. There also is selection within individual organisms (intragenomic conflict), and selection among multi-species communities (an idea that now is getting attention in work on the human microbiome). All four of these levels of selection find a place in multi-level selection theory.

Elliott Sober

What an odd time to be a fundamentalist about adaptation and natural selection - when each major subdiscipline of evolutionary biology has been discovering other mechanisms as adjuncts to selection's centrality.

Stephen Jay Gould

Now let me step back from the problem and very generally discuss natural selection and what we know about it. I think it is safe to say that we know for sure that natural selection, as a process, does work. There is a mountain of experimental and observational evidence, much of it predating genetics, which shows that natural selection as a biological process works.

David M. Raup

When environments change, they usually do so pretty rapidly, at rates with which adaptation by natural selection would be hard put to keep up. When such change occurs, the quality of your adaptation to your old habitat is irrelevant, and any competitive advantage you might have had may be eliminated at a stroke.

Ian Tattersall

This fundamental subject of Natural Selection will be treated at some length in the fourth chapter; and we shall then see how Natural Selection almost inevitably causes much Extinction of the less improved forms of life and induces what I have called Divergence of Character.

Charles Darwin

I think in some ways it would make more sense to have as a poverty level a relative concept and say, the level of poverty is that level of income or that level of consumption below which 10 percent of the people now are.

Milton Friedman

When I passed 7th standard, govt. of Kerala announced a separate sports school for aspiring young girls. During the selection trials, I stood first in district level as well as state level.

P. T. Usha

For me the breath really is the tool which allows you to understand what's happening on the mental level and what's happening on the emotional level, and it also allows you to measure what's happening on a physical level.

Paul Harvey

Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.

Ronald Fisher

Natural selection is a theory of local adaptation to changing environments. It proposes no perfecting principles, no guarantee of general improvement

Stephen Jay Gould

The merger mania which goes on and on and on is the sign of the disappearance of competition. As we deregulate, the mergers increase, which means there's less and less competition. At the national level, at the regional level, but also at the international level.

John Ralston Saul

We have seen a lot more black and minority ethnic coaches at grass-roots level, academy level, development level, but of course at senior level there is a massive void. That is something that has to be addressed and there has to be a pathway for them.

Chris Hughton

We have good examples of successful adaptation to rising sea levels. The Netherlands became a wealthy nation despite having one-third of its landmass below sea level, including areas a full 7m below sea level, as a result of the gradual sinking of its landscapes.

Michael Shellenberger

Creationists argue that natural selection is only a negative process, and therefore cannot create anything. Chopra argues that skepticism is only a negative process, and therefore does not lead to knowledge. Both are wrong for the same reasons. They ignore the generation of diversity and new ideas upon which natural selection and skepticism acts. Weeding out the unfit is critical to both - natural selection allows evolution to proceed, and skepticism allows science to advance.

Steven Novella

A materialist feminist approach to women's oppression destroys the idea that women are a 'natural group' . . . What the analysis accomplishes on the level of ideas, practice makes actual at the level of facts: by its very existence, lesbian society destroys the artificial (social) fact constituting women as a 'natural group.' A lesbian society pragmatically reveals that the division from men of which women have been the object is a political one . . .
