Species Quotes
-
Spraying to kill trees and and raspberry bushes after a clear-cut merely looks unaesthetic for a short time, but tree plantations are deliberate ecodeath. Yet, tree planting is often pictorially advertised on television and in national magazines by focusing on cupped caring hands around a seedling. But forests do not need this godlike interference... Planting tree plantations is permanent deforestation... The extensive planting of just one exotic species removes thousands of native species.
-
I'm sure it has to be a species distinct from us. There is speculation that it could be a diseased human, but this is nothing like that.
-
Two forms or species are sympatric, if they occur together, that is if their areas of distribution overlap or coincide. Two forms (or species) are allapatric, if they do not occur together, that is if they exclude each other geographically. The term allopatric is primarily useful in denoting geographic representatives.
-
If you think about it, every single species is endangered. Homo sapiens at the front of the line, mosquitoes and lawyers at the back.
-
We need to emphasize the more positive aspects of our species.
-
Over 99 percent of all species that ever lived are now extinct.
-
Good and evil are essential differences of the act of the will. For good and evil pertain essentially to the will; just as truth and falsehood pertain to the reason, the act of which is distinguished essentially by the difference of truth and falsehood (according as we say that an opinion is true or false.) Consequently, good and evil volition are acts differing in species.
-
No conclusion is more fully established, than the important fact of the total absence of any vestiges of the human species throughout the entire series of geological formations.
-
Physically, men are of the same species; spiritually each is a species apart.
-
Evolutionary biologists often avoid using the term "race" because there is so much racist baggage that comes with the term. However, they are often okay with the idea that the genealogy of human groups within our species can sometimes be inferred in much the same way as the genealogy of different species.
-
Words are acoustical signs for concepts; concepts, however, are more or less definite image signs for often recurring and associated sensations, for groups of sensations. To understand one another, it is not enough that one use the same words; one also has to use the same words for the same species of inner experiences; in the end one has to have one's experiences in common.
-
Indeed, I was unable to find any evidence whatsoever of the occurrence of a drastic evolutionary acceleration and genetic reconstruction in widespread, populous species.
-
There are never victories in conservation. If you want to save a species or a habitat, it's a fight forevermore. You can never turn your back.
-
The email of the species is deadlier than the mail.
-
Natural selection has ensured that each species achieves the requisite effect somehow, but it doesn't care, so to speak, how the trick is done.
-
Until recently, when both of them went extinct, there were two species of frogs, known as gastric-brooding frogs, that carried their eggs in their stomachs and gave birth to little froglets through their mouths.
-
Our own species evolved under the influence of group selection, as Darwin emphasized when he discussed the evolution of altruism.
-
We're an amazingly adaptive and resilient species. Once we put our mind to global warming, I have no doubt we'll figure a way through here that won't lead to utter calamity.
-
If the organisms in a species now have trait T, and this trait now helps those organisms to survive and reproduce because the trait has effect E, a natural hypothesis to consider is that T evolved in the lineage leading to those current organisms because T had effect E. This hypothesis is "natural," but it often isn't true!
-
The fundamental problem in the origin of species is not the origin of differences in appearance, since these arise at the level of the geographical race, but the origin of genetic segregation. The test of species-formation is whether, when two forms meet, they interbreed and merge, or whether they keep distinct.
-
Understand now what lying is. Any species of designed deception. If the deception is not designed it is not lying. But if you design to make an impression contrary to the naked truth, you lie.
-
Hatred is the spiritual malignancy of our species, and like any other form of cancer, does its most terrible work not outwardly, but from within us.
-
Habitats keep evolving new pageants of species, and we shouldn't interfere.
-
Erwin estimated that the tropics were home to as many as thirty million species of arthropods.
