Quotes on Species

There are a number of attributes of species and populations that are not of any particular selective advantage to any single individual in a population but that are of great advantage to the population as a whole.

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.

Man, by his very nature, tends to give himself an explanation of the world into which he is born. And this is what distinguishes him from the other species. Every individual, even the least intelligent, the lowest of outcasts, from childhood on gives himself some explanation of the world. And with it he manages to live. And without it, he would sink into madness.

The future of life on earth depends on our ability to take action. Many individuals are doing what they can, but real success can only come if there's a change in our societies and our economics and in our politics. I've been lucky in my lifetime to see some of the greatest spectacles that the natural world has to offer. Surely we have a responsibility to leave for future generations a planet that is healthy, inhabitable by all species

You know what a lima bean does when it's attacked by spider mites? It releases this volatile chemical that goes out into the world and summons another species of mite that comes in and attacks the spider mite, defending the lima bean. So what plants have - while we have consciousness, toolmaking, language, they have biochemistry.

The collection of taxes which are not absolutely required, which do not beyond reasonable doubt contribute to public welfare, is only a species of legalized larceny. Under this Republic the rewards of industry belong to those who earn them.

I am a member of a fragile species, still new to the earth, the youngest creatures of any scale, here only a few moments as evolutionary time is measured, a juvenile species, a child of a species. We are only tentatively set in place, error prone, at risk of fumbling, in real danger at the moment of leaving behind only a thin layer of of our fossils, radioactive at that.

Ninety-nine percent of the time humans have lived on this planet we've lived in tribes, groups of 12 to 36 people. Only during times of war, or what we have now, which is the psychological equivalent of war, does the nuclear family prevail, because it's the most mobile unit that can ensure the survival of the species. But for the full flowering of the human spirit we need groups, tribes.

. . . by natural selection our mind has adapted itself to the conditions of the external world. It has adopted the geometry most advantageous to the species or, in other words, the most convenient. Geometry is not true, it is advantageous.

Those of us who witness the degraded state of the environment and the suffering that comes with it cannot afford to be complacent. We continue to be restless. If we really carry the burden, we are driven to action. We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!

No one knows the diversity in the world, not even to the nearest order of magnitude. ... We don't know for sure how many species there are, where they can be found or how fast they're disappearing. It's like having astronomy without knowing where the stars are.

If insemination were the sole biological function of sex, it could be achieved far more economically in a few seconds of mounting and insertion. Indeed, the least social of mammals mate with scarcely more ceremony. The species that have evolved long-term bonds are also, by and large, the ones that rely on elaborate courtship rituals. . . . Love and sex do indeed go together.

Ants make up two-thirds of the biomass of all the insects. There are millions of species of organisms and we know almost nothing about them.

If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)… Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.

I readily admit it is easy to make of horses what we will. Silent, in some ways reserved, they allow us to train them, and to project our ideas upon them; to ride and drive them, and to make them symbolic, perhaps to a greater degree than any other species.

We are a profoundly interconnected species, as the global economic and ecological crises reveal in vivid and frightening detail. We must embrace the simple fact that we are dependent on and accountable to one another.

Once you have become permanently startled, as I am, by the realization that we are a social species, you tend to keep an eye out for the pieces of evidence that this is, by and large, good for us.

We're all born storytellers. It's part of the species. But, more specifically, I suppose a particular combination of sensitivity and trauma made me a writer: an essential disquiet with reality, which required exploration through portrayal.

We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.

Young man, nature is not frightening, it's people who are frightening! You just need to get to know nature and it will become friendly. This creature known as man is of course highly intelligent, he's capable of manufacturing almost anything from rumours to test-tube babies and yet he destroys two to three species every day. This is the absurdity of man.

To dwellers in a wood, almost every species of tree has its voice as well as its feature.
