Quotes About Species

Terrestrial mammals may be ecosystem-controlling "keystone species," like elephants, or ecosystem engineers, like beavers. Well before humans, mammals dominated much of the land. They

ocean competition is usually a scramble—who can get the most per unit time—rather than a contest in which only one competitor gets the spoils. In scramble competitions, the emphasis changes from the competitors themselves to the resources. One expects less antagonism between members of the same species in the fluid, three-dimensional ocean.

If the idea of humanity, of which the most conclusive symbol is the common origin of the human species, is no longer valid, then nothing is more plausible than a theory according to which brown, yellow, or black races are descended from some other species of apes than the white race, and that all together are predestined by nature to war against each other until they have disappeared from the face of the earth.

Work is the activity which corresponds to the unnaturalness of human existence, which is not imbedded in, and whose mortality is not compensated by, the species' ever-recurring life cycle. Work provides an "artificial" world of things, distinctly different from all natural surroundings. Within its borders each individual life is housed, while this world itself is meant to outlast and transcend them all. The human condition of work is worldliness.

I'm an animal rights activist because I believe we won't have a planet if we continue to behave toward other species the way we do.

We don't need to clear the 4 to 6 percent of the Earth's surface remaining in tropical rain forests, with most of the animal and plant species living there.

A single tree in the tropical forest in the south of Mexico has more different species than some European countries.

We are a species that has lost its way. Everything natural, every flower or tree, and every animal have important lessons to teach us if we would only stop, look, and listen.

There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx's Capital.

But sometimes the males of the species brought home shiny, beautiful things, with hope burning in their hearts.

Whether the result of wear, tear, and exhaustion of resources or whether genetically programmed, all life has a finite span and each species has its own particular longevity. For human beings, this would appear to be approximately 100 to 110 years. This means that even were it possible to prevent or cure every disease that carries people off before the ravages of senescence do, virtually no one would live beyond a century or a bit more.

Nature will always win in the end, as it must if our species is to survive.

Every day we, as a species, do so much to destroy Creation's ability to give us life. But that Creation continues to do everything in its power to give us life anyway. And that's true love.

According to Darwin's Origin of Species, it is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is best able to adapt and adjust to the changing environment in which it finds itself.

According to Darwin's Origin of Species, it is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is best able to adapt and adjust to the changing environment in which it finds itself. —LEON C. MEGGINSON, professor of management and marketing at Louisiana State University, 1963

As a species, we were an abomination. All of us.

You believe in Darwinian evolution.

Fear is the mother of all emotion. Before love, hate, spite, grief, rage, and all the rest, there was fear, and fear gave birth to them all, and as every combat soldier knows there are as many incarnations and species of fear as the Eskimo language has words for snow.

Neither knew it at the time, but a line had been crossed that could not be uncrossed- a running leap over a chasm of ignorance and misunderstanding between species and worlds...and a baby step taken into life's endless possibilities for wonder and joy and surprise that could no more be reversed than one's first taste of chocolate. A dog kiss.

I suppose if there were a part of the world in which mastodon still lived, somebody would design a new gun, and men, in their eternal impudence, would hunt mastodon as they now hunt elephant. Impudence seems to be the word. At least David and Goliath were of the same species, but, to an elephant, a man can only be a midge with a deathly sting.

The American species (to the extent that there really is such a thing) is, of course, populist rather than conservative—and for a very forceful reason: America happens to be the only society in creation built by conscious human intent…and developed, by Europeans tired of Europe's ancient commitments, and determined,…each in his own way, on a "new beginning.

Man is not a machine... Although man most certainly processes information, he does not necessarily process it in the way computers do. Computers and men are not species of the same genus... However much intelligence computers may attain, now or in the furture, theirs must always be an intelligence alien to genuine human problems and concerns.

I think we're going to move from a Homo sapiens into a Homo evolutis: … a hominid that takes direct and deliberate control over the evolution of his species, her species and other species.

Sólo a partir de Darwin se ha comprendido que no somos la especie elegida, sino como dice Robert Foley, una especie única entre otras muchas especies únicas.
