Top 1200 Species Quotes & Sayings - Page 3

We must infer that a plant or animal of any species, is made up of special units, in all of which there dwells the intrinsic aptitude to aggregate into the form of that species: just as in the atoms of a salt, there dwells the intrinsic aptitude to crystallize in a particular way.?

Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.

It's fair to say when you go out and walk in the woods or on a beach, the most conspicuous forms of life you will see are plants and animals, and certainly there's a huge diversity of those types of organisms, perhaps 10 million animal species and several hundred thousand plant species.

Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.

The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.

Sight and touch, being thus increased in capacity, might belong to some species far superior to man; or rather the human species would be far different had all the senses been thus improved.

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.

I believe that art is the highest expression of the human spirit. I believe that we yearn to transcend the merely finite and ephemeral; to participate in something mysterious and communal called 'culture' - and that this yearning is as strong in our species as the yearning to reproduce the species.

Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.

The evolutionary vision is agnostic in regard to systems in the universe of greater complexity than those of which human beings have clear knowledge. It recognizes aesthetic, moral, and religious ideas and experiences as a species, in this case of mental structures or of images, which clearly interacts with other species in the world's great' ecosystem.

I don't hold animals superior or even equal to humans. The whole case for behaving decently to animals rests on the fact that we are the superior species. We are the species uniquely capable of imagination, rationality, and moral choice - and that is precisely why we are under an obligation to recognize and respect the rights of animals.

Milk is for babies. Human beings are the only species that drinks milk into adulthood and besides that we prefer to drink the milk of another species (enslaved cows and goats), and we have come to consider it normal when, it is actually a pretty perverse form of sexual abuse!

We [people] have the power to destroy ourselves as well as the environment. As a species we love what I'd call brinks-person-ship, going right to the edge of disaster and somehow managing to pull back and recover. But my bet is still on the creative and playful and positive in the species. I think we will manage to survive and gradually turn things around.

It has been asserted that there is a separate species on the earth to correspond with each one of the stars. Now if the earth provides in each species a focus for the action of each star, why may not a similar provision be made among other heavenly bodies that are subject to the action of their fellows?

To many people, 'biodiversity' is almost synonymous with the word 'nature,' and 'nature' brings to mind steamy forests and the big creatures that dwell there. Fair enough. But biodiversity is much more than that, for it encompasses not only the diversity of species, but also the diversity within species.

When I realized, in 1978, that Lucy did represent a new species of human ancestor, and that I had an opportunity to name this new species, I realized this was a revolutionary step in understanding human origins.

I'd bet almost anything that life from another planet, if formed independently from life on Earth, would be more different from all species of Earth life than any two species of Earth life are from each other.

I not only believe, I believe that there are many different species of ships, there are many different species of extraterrestrials, and not all of them are up to good.

One must believe that every living thing whatsoever must change insensibly in its organization and in its form... One must therefore never expect to find among living species all those which are found in the fossil state, and yet one may not assume that any species has really been lost or rendered extinct.

A large animal needs a large area. If you protect that area, you're also protecting thousands of other plants and animals. You're saving all these species that future generations will want - you're saving the world for your children and your children's children. . . . The destruction of species is final. If you lose a species, you lose the genes, you lose all the potential drugs and potential foods that could be useful to the next generations. The ecosystems will not function as they have.

When students of other sciences ask us what is now currently believed about the origin of species, we have no clear answer to give. Faith has given way to agnosticism. Meanwhile, though our faith in evolution stands unshaken we have no acceptable account of the origin of species.

Each of these [bacterial] species are masterpieces of evolution. Each has persisted for thousands to millions of years. Each is exquisitely adapted to the environment in which it lives, interlocked with other species to form ecosystems upon which our own lives depend in ways we have not begun even to imagine.

Why were there far more species of domesticated animals in Eurasia than in the Americas? The Americas harbor over a thousand native wild mammal species, so you might initially suppose that the Americas offered plenty of starting material for domestication.

If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.

Politicians need a better understanding of global ecology. We need to be freed from our species-specific arrogance. No evidence exists that we are chosen, the unique species for which all the others were made. Nor are we the most important one because we are so numerous, powerful and dangerous.

Poetry, song, stories, art, our reverence for nature, are key to our survival as a species, and to the survival of all species, I believe. You can't always extract such emphatic hunches and activist stances from a scientific maxim or mathematical axiom.

The astounding variety of foods on offer in the modern supermarket obscures the fact that the actual number of species in the modern diet is shrinking. For reasons of economics, the food industry prefers to tease its myriad processed offerings from a tiny group of plant species, corn and soybeans chief among them.

We're at risk of losing this iconic species for all time. Once it's stripped of its natural instincts, it's no longer a tiger. But there's a lot of species like that. The more intriguing thing, throughout Asia, a lot of these countries are selling off their jungle-and-forest rights for oil and for paper-and-pulp companies.

There are many ways for organisms to probe the external world. Some smell it, others listen to it, many see it. Each species, therefore, lives in its own unique sensory world of which other species may be partially or totally unaware.

Perceptual reality is different for different species. In certain species it is a mode of observation, so what we call scientific fact is actually not ultimate truth, it is perceptual experience, and it's a mode of observation.

There are landscapes and species that are not going to be here a hundred years from now, fifty years from now. One gift we as writers give to the world is to bear witness to these landscapes and species as we have experienced them.

The immune system has evolved the capacity to react specifically with a very large number of foreign molecules with which it had no previous contact while avoiding reactivity for autologous molecules, naturally antigenic in other species or in other individuals of the same species.

Man makes history; woman is history. The reproduction of the species is feminine: it runs steadily and quietly through all species, animal or human, through all short-lived cultures. It is primary, unchanging, everlasting, maternal, plantlike, and cultureless. If we look back we find that it is synonymous with life itself.

It's our human nature to explore. Tens of thousands of years ago, our species walked out of Africa, traveling far and wide across the entire planet, from the Arctic to the tip of Tierra Del Fuego, making us the most geographically diversified species on Earth.

Bacteria live in unbelievable mixtures of hundreds or thousands of species. Like on your teeth. There are 600 species of bacteria on your teeth every morning.

Most species do their own evolving, making it up as they go along, which is the way Nature intended. And this is all very natural and organic and in tune with mysterious cycles of the cosmos, which believes that there's nothing like millions of years of really frustrating trial and error to give a species moral fiber and, in some cases, backbone.

Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it.

Could it be that the atomic isolation of the husband and wife nucleus with an orbiting child or two is in fact a culturally imposed aberration for our species? As ill-suited to our evolved tendencies as corsets, chastity belts, and suits of armor? ...a distorted and distorting family structure inappropriate for our species?

It's partly the fault of the institutions of education. But it's partly the decision to be relieved of responsibility. Literature is simply the most focused form of the demands on the evolution of the species. It imposes a certain responsibility, moral, ethical and esthetic responsibility, and the species simply doesn't want to oblige.

Each species may have had its origin in a single pair, or individual, where an individual was sufficient, and species may have been created in succession at such times and in such places as to enable them to multiply and endure for an appointed period, and occupy an appointed space on the globe.

I had found again and again that the most aberrant population of a species - often having reached species rank, and occasionally classified even as a separate genus - occurred at a peripheral location, indeed usually at the most isolated peripheral location.

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.

We're being challenged to do something so profound, it's unprecedented in the history of our species, and there couldn't be more at stake. It's not even our species at stake; it's the whole dream of life on earth that's taken 4.5 billion years to realize - all this beautiful pastoral life on earth.

If we consider the superiority of the human species, the size of its brain, its powers of thinking, language and organization, we can say this: were there the slightest possibility that another rival or superior species might appear, on earth or elsewhere, man would use every means at his disposal to destroy it.

Man, who preys both on the vegetable and animal species, is himself a prey to neither. He too possesses the reproductive principle far beyond the degree requisite for the bare continuance of his species. What becomes of the surplus of human life to which this principle is competent?

Politicians need a better understanding of global ecology. We need to be freed from our species-specific arrogance. No evidence exists that we are 'chosen', the unique species for which all the others were made. Nor are we the most important one because we are so numerous, powerful and dangerous.

Power over seems to be driving our very young species into a ditch because it's from an old competitive, "there may not be enough" kind of framework of scarcity. Power with is thinking abundantly as opposed to fearfully. Power with is hopefully where we're going - and where we need to go as a species in order to survive.

Eighty-two percent of Australia's bird species and two thirds of Australia's mammal species can be found on our (Australian Wildlife Conservancy) reserves. We put teams of people on the frontline in the battle against feral animals, wildfires and noxious weeds. Science underpins everything we do.

I hope we have learned throughout centuries of revolution and reaction that it's really a shift in consciousness that we need. And I think there is a shift in consciousness among our human species. I think the human species is evolving, spiritually.

The passenger pigeon, the golden toad, the Caspian tiger: they are all gone, and other species hang by a thread. Our actions are not merely driving other species to extinction: we threaten our own survival, too, by destabilising ecosystems and destroying biodiversity.

We're the only species that have crapped up the planet and the only species that can clean it up.

As a species, we're always seeking out authenticity. We're dying for authenticity. We smell it immediately, and we also smell even the slightest riff of somebody who's not completely true to who they are. We have that ability because, as a species, we have organized around stories. We tell them and we subscribe to them.

An Individual, whatever species it might be, is nothing in the Universe. A hundred, a thousand individuals are still nothing. The species are the only creatures of Nature, perpetual creatures, as old and as permanent as it. In order to judge it better, we no longer consider the species as a collection or as a series of similar individuals, but as a whole independent of number, independent of time, a whole always living, always the same, a whole which has been counted as one in the works of creation, and which, as a consequence, makes only a unity in Nature.

Humanity is part of nature, a species that evolved among other species. The more closely we identify ourselves with the rest of life, the more quickly we will be able to discover the sources of human sensibility and acquire the knowledge on which an enduring ethic, a sense of preferred direction, can be built.

In the long run, the only solution I see to the problem of diversity is the expansion of mankind into the universe by means of green technology... Green technology means we do not live in cans but adapt our plants and our animals and ourselves to live wild in the universe as we find it... When life invades a new habitat, she never moves with a single species. She comes with a variety of species, and as soon as she is established, her species spread and diversify further. Our spread through the galaxy will follow her ancient pattern.

Survivor species tend to have huge populations, so they can afford to lose many individuals and still survive as a species. They also tend to be small. If you're small, you need less food - which is great in a situation where famine is everywhere.

The only event in the history of our species that compares with this one is Genesis. And this is a new kind of Genesis, the Genesis of our species into conscious awareness.

My premise is that there's something hardwired into our DNA, that we as a species came and evolved from caves and clans and tribes, and therefore, we as a species care more about the things that are local to us than we care about the things that are 'over there' from us.

The various processes of belief acquisition which are native to a species include ones which may allow for the reliable pick-up of information, which, in turn, allows individual members of the species to successfully negotiate their environment and satisfy their various desires.

The most important thing for our species is, before it speaks, to listen to its environment. That has a higher priority in any species' survival. We need to be listening to our environment - in other words, restoring the quiet - not just to our natural areas, but also to towns like Portland, Maine.
