Everything in nature is the result of fixed laws.
Charles DarwinRead
I think it inevitably follows, that as new species in the course of time are formed through natural selection, others will become rarer and rarer, and finally extinct. The forms which stand in closest competition with those undergoing modification and improvement will naturally suffer most.
Interpretation
This quote discusses the process of natural selection leading to the extinction of species that cannot adapt.
Charles Darwin highlights the inevitable consequences of natural selection, where as new species evolve and adapt to their environment, those that cannot keep pace will become less common and may ultimately face extinction. This reflects the competitive nature of evolution, where species in direct competition with those evolving will struggle for survival.
In practice
In a biology class discussing evolution, this quote can be used to illustrate the concept of natural selection.
Everything in nature is the result of fixed laws.
The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
I am quite conscious that my speculations run beyond the bounds of true science....It is a mere rag of an hypothesis with as many flaw[s] & holes as sound parts.
We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
we are always slow in admitting any great change of which we do not see the intermediate steps
It is my supposition that the Universe in not only queerer than we imagine, is queerer than we can imagine.
I am a futurist, projecting trends in science into the next decades and century, but ironically my two daughters - one is a neuroscientist and the other is a pastry chef - tell me that my taste in music is positively prehistoric.
Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'Ye must have faith.'
[Bacteria] have an incredibly complicated chemical lexicon that ... allows bacteria to be multicellular. In the spirit of TED they're doing things together because it makes a difference.
We have such a terrible, terrible misconception of science. We think it involves the definite, the precise, the known; it is a horrid series of gates to an unknown as vast of the universe; which means endless.
A theory should not attempt to explain all the facts, because some of the facts are wrong
