A Quote by Charles Darwin
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.

I think like almost everything in evolution, the old forms persist. New forms come along - not always, of course; there are species and whole lineages that go extinct - but basically novels and plays, and so on, will continue to exist. Jokes, as the lowest-cost form of narrative, will certainly continue to exist. They're a bit like microbes in the biological world. They're low-cost and they're everywhere. They're the most successful form of life, even though they're not the ones we think about most.
This fundamental subject of Natural Selection will be treated at some length in the fourth chapter; and we shall then see how Natural Selection almost inevitably causes much Extinction of the less improved forms of life and induces what I have called Divergence of Character.
All history shows that, in exact proportion as nations advance in civilisation, the accounts of miracles taking place among them become rarer and rarer, until at last they entirely cease.
[1.] And first I suppose that there is diffused through all places an aethereal substance capable of contraction & dilatation, strongly elastick, & in a word, much like air in all respects, but far more subtile. 2. I suppose this aether pervades all gross bodies, but yet so as to stand rarer in their pores then in free spaces, & so much ye rarer as their pores are less ... 3. I suppose ye rarer aether within bodies & ye denser without them, not to be terminated in a mathematical superficies, but to grow gradually into one another.
We live in a world where it's so accessible to date now, which is great. I don't judge that. We have so many ways of meeting people. I like to meet someone and have that chivalry, to take them out on a date and actually be a gentleman. I think that's becoming rarer and rarer.
Then from the world all spirituality will be extinct, all moral perfection will be extinct, all sweet-souled sympathy for religion will be extinct, all ideality will be extinct; and in its place will reign the duality of lust and luxury as the male and female deities, with money as its priest, fraud, force, and competition its ceremonies, and the human soul its sacrifice. Such a thing can never be.
I think it's becoming rarer and rarer when I consider the experiences that I've had in my life between my dad and my brother and all the men in my life who have all been gentlemen and have looked after women.
Truth telling is the first building block of character -- a quality that seems to be getting rarer and rarer in all-forgiving America.
A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct.
The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology.
Of the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.
Fair are the flowers and the children, but their subtle suggestion is fairer;
Rarer is the roseburst of dawn, but the secret that clasps it rarer;
Sweet the exultance of song, but the strain that precedes it is sweeter
And never was poem yet writ, but the meaning outmastered the meter.
Having your own space is getting rarer and rarer these days. It's dangerous giving someone like me - who grew up fantasizing about studios and records - the freedom and resources to build your own studio. I would just live in it, which is what I pretty much did for all of the '90s.
Kind thoughts are rarer than either kind words or deeds. They imply a great deal of thinking about others. This in itself is rare. But they also imply a great deal of thinking about others without the thoughts being criticisms. This is rarer still.
When a parasite moves to a new habitat, it can find new hosts through a process called the trans-species jump. Often, the new host has no resistance; it and the parasite haven't had time to adjust to each other through natural selection (it is frequently not in the best interest of a parasite to kill its host quickly).
One animal or plant species may become extinct every hour. All species are doomed to extinction, but man through worldwide development/killing animals for food/profit/using toxic chemicals such as pesticides/industrial wastes, will accelerate the extinction of plants/animals and the result will be a more hostile environment for man.
