Read through the most famous quotes by topic #extinct
Unless one says goodbye to what one loves, and unless one travels to completely new territories, one can expect merely a long wearing away of oneself and an eventual extinction. ↗
Without death there is little innovation. Extinction - death of a species - is part and parcel of evolutionary change. In the absence of this kind of extinction new developments would not prosper. In our own history, periods when ideas have been perpetuated by dogma, preventing the replacement of old by new ideas, have also been times of stultifying stagnation. The Dark Ages in western society were the most static, least innovative of times. So the fact that trilobites were replaced by batches of successive species through their long history was a testimony to their evolutionary vigour. ↗
We must allow ourselves to think, we must dare to think, even though we fail. It is in the nature of things that we always fail, because we suddenly find it impossible to order our thoughts, because the process of thinking requires us to consider every thought there is, every possible thought. Fundamentally we have always failed, like all the others, whoever they were, even the greatest minds. At some point, they suddenly failed and their system collapsed, as is proved by their writings, which we admire because they venture farthest into failure. To think is to fail, I thought. ↗
It is a rule in paleontology that ornamentation and complication precede extinction. And our mutation, of which the assembly line, the collective farm, the mechanized army, and the mass production of food are evidences or even symptoms, might well correspond to the thickening armor of the great reptiles—a tendency that can end only in extinction. If this should happen to be true, nothing stemming from thought can interfere with it or bend it. Conscious thought seems to have little effect on the action or direction of our species. ↗
Life has had to deal with environmental change, especially climate change, since the beginning of its existence on Earth. Species adjust or go extinct, and both have happened. For life-forms with our kinds of cells—eukaryotic, the kind with distinct organelles—the average existence of a species is about 1 million years, and, on average, one species goes extinct a year, at least of the species we have named and know, including those we know only from fossil records." -Dan Botkin, excerpt from THE MOON IN THE NAUTILUS SHELL.

There are species that retain their characteristics even in conditions that are relatively different from their natural ones; other species in similar circumstances instead become extinct; otherwise what takes place is racial mixing with other elements in which no assimilation or real evolution occurs. The result of this interbreeding closely resembles Mendel’s laws concerning heredity: once it disappears in the phenotype, the primitive element survives in the form of a separated, latent heredity that is capable of cropping up in sporadic apparitions, even though it is always endowed with a character of heterogeneity in regard to the superior type. ↗
