I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable.
Of the twenty or so civilizations known to modern Western historians, all except our own appear to be dead or moribund, and, when we diagnose each case, in extremis or post mortem, we invariably find that the cause of death has been either War or Class or some combination of the two. To date, these two plagues have been deadly enough, in partnership, to kill off nineteen out of twenty representatives of this recently evolved species of human society; but, up to now, the deadliness of these scourges has had a saving limit.Arnold Joseph Toynbee
Individuals of the earlier species had suffered from an almost insurmountable spiritual isolation from one another. Not even lovers, and scarcely even the geniuses with special insight into personality, ever had anything like accurate vision of one another. [T]he most precious gift that a lover could bring to the beloved was not virginity but sexual experience. The union, it was felt, was the more pregnant the more each party could contribute from previous sexual and spiritual intimacy with others.Olaf Stapledon
The core of ethics runs deep in our species and is common to human beings everywhere. It survives the most appalling hardships and the most ruthless attempts to deprive human beings of their humanity. Nevertheless, some people resist the idea that his core has a biological basis which we have inherited from our pre-human ancestors.peter singer
Only within the 20th Century has biological thought been focused on ecology, or the relation of the living creature to its environment. Awareness of ecological relationships is or should be the basis of modern conservation programs, for it is useless to attempt to preserve a living species unless the kind of land or water it requires is also preserved. So delicately interwoven are the relationships that when we disturb one thread of the community fabric we alter it all perhaps almost imperceptibly, perhaps so drastically that destruction follows.rachel carson
Scott quoted a famous geneticist, who said, "Nothing in biology makes sense except in the light of evolution." I would like to drop one word, so that the quote is true. It should read, "Nothing in biology makes sense in the light of evolution." For example, evolution has no explanation as to why and how around 1.4 million species of animals evolved as male and female. No one even goes near explaining how and why each species managed to reproduce (during the millions of years the female was supposedly evolving to maturity) without the right reproductive machinery.ray comfort
As soon as we cease to believe in such an engineer and in a discourse which breaks with the received historical discourse, and as soon as we admit that every finite discourse is bound by a certain bricolage and that the engineer and the scientist are also species of bricoleurs , then the very idea of bricolage is menaced and the difference in which it took on its meaning breaks down.jacques derrida
My feeling is that Darwinism is only at best a partial solution, and an extremely dangerous partial solution. I would say, based on the little I know, Darwinism explains microevolution within species quite well. As to its broader consequence and implications, I don't think it explains individual species evolution at all well.ben stein
Grief is a species of idleness.
Night after night the nightingale came to beg for divine love, but though the rose trembled at the sound of his voice, her petals remained closed to him...Flower and bird, two species never meant to mate. Yet at length the rose overcame her fear and from that single, forbidden union was born the red rose that Allah never intended the world to know.susan kay
Nobody, I believe, will deny, that we are to form our judgment of the true nature of the human mind, not from sloth and stupidity of the most degenerate and vilest of men, but from the sentiments and fervent desires of the best and wisest of the species.robert leighton
Artificial flight may be defined as that form of aviation in which a man flies at will in any direction by means of an apparatus attached to his body, the use of which requires personal skill. Artificial flight by a single individual is the proper beginning for all species of artificial flight, as the necessary conditions can most easily be fulfilled when man flies individually.otto lilienthal
Nec species sua cuique manet, rerumque novatrixEx aliis alias reddit natura figuras.Nec perit in toto quidquam, mihi credite, mundo,Sed variat faciemque novat: nascique vocaturIncipere esse aliud, quàm quod fuit antè; moriqueDesinere illud idem; quum sint huc forsitan illa,Haec translata illuc; summâ tamen omnia constant.ovid
This great increase of the quantity of work which, in consequence of the division of labour, the same number of people are capable of performing, is owing to three different circumstances; first, to the increase of dexterity in every particular workman; secondly, to the saving of the time which is commonly lost in passing from one species of work to another; and lastly, to the invention of a great number of machines which facilitate and abridge labour, and enable one man to do the work of many.Adam Smith
Each of the major sciences has contributed an essential ingredient in our long retreat from an initial belief in our own cosmic importance. Astronomy defined our home as a small planet tucked away in one corner of an average galaxy among millions; biology took away our status as paragons created in the image of God; geology gave us the immensity of time and taught us how little of it our own species has occupied.stephen jay gould
If the resident zoologist of Galaxy X had visited the earth 5 million years ago while making his inventory of inhabited planets in the universe, he would surely have corrected his earlier report that apes showed more promise than Old World monkeys and noted that monkeys had overcome an original disadvantage to gain domination among primates. (He will confirm this statement after his visit next year but also add a footnote that one species from the ape bush has enjoyed an unusual and unexpected flowering, thus demanding closer monitoring.)stephen jay gould
Great problems are now being handled, keeping every thinking man in suspense; the unity or multiplicity of human races; the creation of man 1,000 years or 1,000 centuries ago; the fixity of species, or the slow and progressive transformation of one species into another; the eternity of matter; the idea of a God unnecessary: such are some of the questions that humanity discusses nowadays.Louis Pasteur
"It is no shame to lose to me, mortal. Even among mythical creatures there are very few who can give a unicorn a good game." "I am pleased that you were not wholly bored," Martin said. "Now will you tell me what you were talking about concerning the destruction of my species?" "Oh, that," Tlingel replied.roger zelazny
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.murray bookchin
Throughout human history, as our species has faced the frightening, terrorizing fact that we do not know who we are, or where we are going in this ocean of chaos, it has been the authorities the political, the religious, the educational authorities who attempted to comfort us by giving us order, rules, regulations, informing forming in our minds their view of reality. To think for yourself you must question authority and learn how to put yourself in a state of vulnerable open-mindedness, chaotic, confused vulnerability to inform yourself.
The anthropologists got it wrong when they named our species Homo sapiens ('wise man'). In any case it's an arrogant and bigheaded thing to say, wisdom being one of our least evident features. In reality, we are Pan narrans, the storytelling chimpanzee.terry pratchett
In nature, G. hirsutum and G. barbadense are perennial shrubs. However, in the agricultural system both species are cultivated as annuals, with destruction of plants after harvesting the fruit for seed and fibre. The plants are mainly grown for their fibre, cotton lint, which is used in textiles and clothing.
Siquidem et per naturam pleraque mutationem recipiunt, et corrupta in diversas species transformantur; sicut de vitulorum carnibus putridis apes, sicut de equis scarabei, de mulis locustae, de cancris scorpiones.
