Species Replacement Quotes

Even if the whole human race dies off because we keep fighting and killing each other and being heartless, the planet will take care of itself. Eventually, after millions of years, it will cleanse itself, and new life forms, maybe better ones, will come. Meanwhile, we'll have gotten exactly what we deserved: annihilation.

At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace throughout the world the savage races. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break will then be rendered wider, for it will intervene between man in a more civilised state as we may hope, than the Caucasian and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla.

The climate of our culture is changing. Under these new rains, new suns, small things grow great, and what was great grows small; whole species disappear and are replaced.

Biological diversity is the key to the maintenance of the world as we know it... Eliminate one species, and another increases to take its place. Eliminate a great many species, and the local ecosystem starts to decay.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.

And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.

It should soon be possible dramatically to increase the intelligence and life span of a few individuals. They and their offspring could become a master race. Evolution pays no regard to social justice. It was not fair on the Neanderthals they were replaced by modern humans.

To me it seems that the warm blooded dinosaurs replaced advanced mammal ancestors that were warm blooded, also.

the day the asteroid hit the Yucatan Peninsula and wiped out the dinosaurs, making room for our little primate ancestors to grow big and brainy and to take over the planet.

I suppose we need not go mourning the buffaloes. In the nature of things, they had to give place to better cattle, though the change might have been made without barbarous wickedness.

We'll all die out eventually. Humans will be gone. And all I'm saying is, when people worry about polar bears disappearing or whatever, it's like, 'Well that's life, things will come and go, we'll find new species.'
