Everything in nature is the result of fixed laws.
It at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed.
Interpretation
What this quote means
This quote expresses the idea of natural selection where advantageous traits are retained while disadvantageous ones are eliminated.
Charles Darwin's quote encapsulates the principle of natural selection, a fundamental concept in evolutionary biology. It suggests that in any given environment, traits that enhance survival and reproduction are more likely to be passed on to future generations, while traits that hinder these processes are likely to be lost over time. This process of preservation and destruction of variations shapes the evolution of species, highlighting the dynamic interplay between organisms and their environments.

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

A strong feeling of adventure is animating those who are working on bacterial viruses, a feeling that they have a small part in the great drive towards a fundamental problem in biology.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences. The secret of antibody diversity would emerge from that. Fortunately at the time I was sufficiently ignorant of the subject not to realise how naive I was being.
My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium.
If a sect does officially insist that its structure of belief demands that evolution be false, then no compromise is possible. An honest and competent biology teacher can only conclude that the sect's beliefs are wrong and that its religion is a false one.
