Everything in nature is the result of fixed laws.
Charles DarwinRead
To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.
Interpretation
Darwin expresses skepticism about the evolution of the eye through natural selection due to its complexity.
In this quote, Charles Darwin conveys his belief that the intricate design of the eye, with its various sophisticated features for focus, light adjustment, and correction of visual distortions, cannot reasonably be attributed to the process of natural selection. He finds the notion absurd, reflecting on the remarkable complexities of biological structures that challenge simplistic evolutionary explanations.
In practice
This quote can be used in a discussion about the intricacies of biological systems in a biology class.
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
Ideas which have been developed simultaneously or in immediate succession in the same mind mutually reproduce each other, and do this with greater ease in the direction of the original succession and with a certainty proportional to the frequency with which they were together
It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them.
The time has come to recognize that food, how we produce it, process it, package it, sell it, cook it and eat it, is as important as any other issue.
It felt—nearly twenty-five hundred years after Hippocrates had naively coined the overarching term karkinos—that modern oncology was hardly any more sophisticated in its taxonomy of cancer.
We were staring at the origin of a piece of our own bodies inside this 375-million-year-old fish. We had a fish with a wrist.
There has been so much underestimating of animal cognition that to perhaps overestimate it, as I probably do, is probably a healthy reaction.
