A Quote by Richard Koch
If we want to sum up the theory of evolution by natural selection in two words, which have great relevance for all societies and businesses, we should simply remember: diversity works.

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.
The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology.
I believe in the theory of evolution, but I believe as well in the allegorical truth of creation theory. In other words, I believe that evolution, including the principle of natural selection, is one of the tools used by God to create mankind. Mankind is then a participant in the creation of the universe itself, so that we have a closed loop. I believe that there is a level on which science and religious metaphor are mutually compatible.
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.
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.
Memetics provides a new approach to the evolution of language in which we apply Darwinian thinking to two replicators, not one. On this theory, memetic selection, as well as genetic selection, does the work of creating language.
The theory of evolution by cumulative natural selection is the only theory we know of that is in principle capable of explaining the existence of organized complexity.
Human rights are an aspect of natural law, a consequence of the way the universe works, as solid and as real as photons or the concept of pi. The idea of self- ownership is the equivalent of Pythagoras' theorem, of evolution by natural selection, of general relativity, and of quantum theory. Before humankind discovered any of these, it suffered, to varying degrees, in misery and ignorance.
The theory of evolution by natural selection is an ecological theory-founded on ecological observation by perhaps the greatest of all ecologists. It has been adopted by and brought up by the science of genetics, and ecologists, being modest people, are apt to forget their distinguished parenthood.
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.
The fuel for evolution is diversity, with natural selection leading to continuous adaptations and improvements in Nature's handiwork.
The main goal is to increase diversity. The one thing that is bad for society is low diversity. This is true for culture or evolution, for species and also for whole societies. If you become a monoculture, you are at great risk of perishing.
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.
Alfred Russel Wallace, the codiscoverer of the theory of natural selection. Following their twin announcements of the theory in 1858, both Darwin and Wallace struggled like Laocoöns with the serpentine problem of human evolution and its encoiling difficulty of consciousness. But where Darwin clouded the problem with his own naivete, seeing only continuity in evolution, Wallace could not do so.
Notable enough, however, are the controversies over the series 1 - 1 + 1 - 1 + 1 - ... whose sum was given by Leibniz as 1/2, although others disagree. ... Understanding of this question is to be sought in the word "sum"; this idea, if thus conceived - namely, the sum of a series is said to be that quantity to which it is brought closer as more terms of the series are taken - has relevance only for convergent series, and we should in general give up the idea of sum for divergent series.
Of course, there is no reconciliation between the theory of evolution by natural selection and the traditional religious view of the origin of the human mind.
