Arthur C. Clarke Quotes

As some species die out, forms better adapted to utilize the obstacles against which they struggled in vain come into being.

This is the rollcall of evolution happening in the space of a few generations, the greatest loss of living things that make up our biodiversity since the disappearance of the dinosaurs.

Adapt or perish, now as ever, is nature's inexorable imperative.

Everything has to evolve or else it perishes.

If you do not change, you can become extinct !

We can be the new brand of self-extincting dinosaurs or we can evolve.

There are two options: adapt or die.

IF you don't change, you can become extinct!

Every species becomes extinct; at some point, we will go extinct. The question is, as Homo sapiens, are we going to be able to adapt to the change that we're actually part of? We're causing such dramatic changes to the planet, so yes, you do stop and think, 'I wonder where we're headed.'

Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.

The dinosaurs became extinct because they didn't have a space program.

We are beginning to resemble extinct dinosaurs, who suffered from too much armor and too little brain.

We've almost been wiped out as a species many times, going back millions of years, and we've survived by reinventing ourselves and enlarging our circles of awareness, inventing new technologies and social structures.

Most organisms either adapt and become part of the system, or get wiped out. The only thing we have to adapt to the system with is our brain. If we don't use it, and we don't adapt fast enough, we won't survive.

Often in evolutionary processes a species must adapt to new conditions in order to survive. Today the atomic bomb has altered profoundly the nature of the world as we know it, and the human race consequently finds itself in a new habitat to which it must adapt its thinking.

It's like the animal kingdom. Adapt or go extinct.

Those who refused to respond to the new stimulus would perish. Adapt or perish.

If we measured success by longevity, then dinosaurs must rank as the number one success story in the history of land life.

A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct.

To exist is to adapt, and if one could not adapt, one died and made room for those who could.

It at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed.

It was the bumble bee and the butterfly who survived, not the dinosaur.

In the history of the world the prize has not gone to those species which specialized in methods of violence, or even in defensive armor. In fact, nature began with producing animals encased in hard shells for defense against the ill of life. But smaller animals, without external armor, warm-blooded, sensitive, alert, have cleared those monsters off the face of the earth.

Where the environment is too soft and luxurious and no strife is required for survival, not only are weak strains and individuals allowed to survive and encouraged to breed but the strong types also grow fat mentally and physically.

Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress.
