Everything in nature is the result of fixed laws.
Charles DarwinRead
The plow is one of the most ancient and most valuable of man's inventions; but long before he existed the land was in fact regularly plowed, and still continues to be thus plowed by earthworms. It may be doubted whether there are many other animals which have played so important a part in the history of the world, as have these lowly organized creatures.
Interpretation
Earthworms have been essential to soil health and cultivation long before humans invented plows.
In this quote, Charles Darwin highlights the vital role that earthworms play in the ecosystem, particularly in the cultivation of the land. He points out that while the plow is a significant human invention for agriculture, earthworms have naturally performed the function of plowing the earth, enriching the soil and contributing to its fertility for eons, underscoring the importance of seemingly simple and 'lowly' organisms in the grand scheme of the worldβs history.

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 better to have 100 functions operate on one data structure than to have 10 functions operate on 10 data structures.
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.
As we look out into the Universe and identify the many accidents of physics and astronomy that have worked together to our benefit, it almost seems as if the Universe must in some sense have known that we were coming.
So how can we test the idea that the transition from nonlife to life is simple enough to happen repeatedly? The most obvious and straightforward way is to search for a second form of life on Earth. No planet is more Earth-like than Earth itself, so if the path to life is easy, then life should have started up many times over right here.
One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.
In no other branch of mathematics is it so easy for experts to blunder as in probability theory.
