Nature is indifferent to the survival of the human species, including Americans.
I don't think of kids as a lower form of the human species.
In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.
The human species' foremost task and unshakable duty is survival.
An evolutionary perspective of our place in the history of the earth reminds us that Homo sapiens sapiens has occupied the planet for the tiniest fraction of that planet's four and a half thousand million years of existence. In many ways we are a bio...
Where do we say that a cell became a blade of grass, which became a starfish, which became a cat, which became a donkey, which became a human being? There's a real lack of evidence from change from actual species to a different type of species.
The human species was not born into a market economy. Bees won't sell you honey if you offer them an electronic funds transfer. The human species imagined money into existence, and it exists - for us, not mice or wasps - because we go on believing in...
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.
If current technological processes continue without change, the environment will change, and we, the human species, will either have to mutate or even die, to disappear, as many species have disappeared.
Crime is a fact of the human species, a fact of that species alone, but it is above all the secret aspect, impenetrable and hidden. Crime hides, and by far the most terrifying things are those which elude us.
The human race has the capacity to render itself extinct unless alternatives are found to the patterns of intraspecific warfare that have dominated civilized history. Ours has long been a predatory species. Living, for humans, depends upon the abilit...
Like all animals, human beings have always taken what they want from nature. But we are the rogue species. We are unique in our ability to use resources on a scale and at a speed that our fellow species can't.
You should know as much as you can about the human species if you have a hand in designing human society.
We are a biological species arising from Earth’s biosphere as one adapted species among many; and however splendid our languages and cultures, however rich and subtle our minds, however vast our creative powers, the mental process is the product of...
Humans are only one species of millions. To kill millions of species for the benefit of one is insane, just as killing millions of people for the benefit of one person would be insane. And since unimpeded ecological collapse would kill off humans any...
The mode of consciousness of nonhuman species is quite different from human consciousness.
It may be underfunded and at times mismanaged, but the [Endangered Species] Act is an unprecedented attempt to delegate human-caused extinction to the chapters of history we would rather not revisit: the Slave Trade, the Indian Removal Policy, the su...
Yes, the human race is a small species in an infinite universe filled with many other planets and many other things, but though small; this race is bearer of very great and big things: Destiny, Virtue, Hope, Love... and that's what makes this species...
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.
People are still very uncomfortable with the idea that humans are not specially created species. I believe we are a fantastic species. But we are not created specially. That's very hard for people to accept in their day-to-day routine.
The Englishman wants to be recognized as a gentleman, or as some other suitable species of human being, the American wants to be considered a good guy.
