Everything in nature is the result of fixed laws.
Charles DarwinRead
When the sexes differ in beauty, in the power of singing, or in producing what I have called instrumental music, it is almost invariably the male which excels the female.
Interpretation
The quote highlights that in certain traits, such as beauty and musical ability, male members of a species often surpass females.
In this quote, Charles Darwin observes a trend found in various species where males tend to exhibit superior characteristics related to beauty, vocal ability, or instrumental talents compared to females. This phenomenon can be attributed to evolutionary processes, where males may display these traits to attract females or deter rivals, ultimately influencing mating success and species propagation.
In practice
In a lecture on evolutionary biology, this quote could illustrate the concept of sexual dimorphism.
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
Haemoglobin is a very large molecule by ordinary standards, containing about ten thousand atoms, but the chances are that your haemoglobin and mine are identical, and significantly different from that of a pig or horse. You may be impressed by how much human beings differ from one another, but if you were to look into the fine details of the molecules of which they are constructed, you would be astonished by their similarity.
To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
The world today is made, it is powered by science; and for any man to abdicate an interest in science is to walk with open eyes towards slavery.
We have to understand the ubiquity of energy in everything we do. Energy is core to our economy and it brings with it environmental challenges, and it's core to our security challenges.
I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments, and demonstrations.
As scientists, we track down all promising leads, and there's reason to suspect that our universe may be one of many - a single bubble in a huge bubble bath of other universes.
