Quotes about evolution

Everything was an artifact of its function. That’s what made evolution so gorgeous.

“Can you think of anything, my dear Mr. Fell, more intricately complex, more perfectly compact and thoroughly functional than the human eye?”

“No, sir,” said August.

“I thought not,” said Larchcroft. “Consider this, though. Our eyes were created by light. Without the existence of light, we would not have eyes. Over the long course of man’s evolutionarily maturation to his modern condition, light sculpted these magical orbs, making subtle adjustments through the centuries, until now they are capable of the incredible process of sight. This most vital sense, not only a means of self-preservation but the single most important catalyst for culture, is a product of the inherent genius of light.”

Not long ago, there were only thought to be six thousand bird species on earth. Ten years from now, most ornithologists believe, there will be three times that many. It isn’t that new species are evolving; rather, scientists are arriving at new definitions of what species are. This advanced thinking – and birds are on the cutting edge of it – has profound implications for human understanding. Speciation is evolution. Evolution is at the heart of who we are, what life is on this planet.

It had taken a couple of billion years to produce me. In that couple of billion years, I had millions upon millions of ancestors. Slime-like ancestors, jelly-like ancestors, water-breathing ancestors, air-breathing ancestors, ancestors that floated, that swam, that crawled, that ran, that climbed, that finally walked. And all of those ancestors, no matter how different, had one thing in common.

They had survived long enough to have descendants. Other species didn’t and their lines were extinct, bare bones in rock strata. But no matter how scarce food got, no matter what enemies they faced, what unprecedented natural upheavals they had to adjust to, my ancestors somehow managed to pull through, and have offspring. That’s how I happen to be here.

Evolution does not obey human notions of morality, nor is human morality a reflection of some natural law. The deadly sins would be different if they mirrored evolutionary no-no’s. Lust, for one, would be deemed a virtue; chastity would be deplored.

And now, out among the stars, evolution was driving toward new goals. The first explorers of Earth had long since come to the limits of flesh and blood; as soon as their machines were better than their bodies, it was time to move. First their brains, and then their thoughts alone, they transferred into shining new homes of metal and of plastic. In these, they roamed among the stars. They no longer built spaceships. They were spaceships.

Outside the tropics, the glaciers slew those who had prematurely left their ancestral home. But, unlike so many others, the man-apes had not merely become extinct - they had been transformed.

The toolmakers had been remade by their own tools.

Moon-Watcher had no idea of its cause, still less of its cure; but discontent had come into his soul, and he had taken one small step toward humanity.

The dowager smiled. “What an interesting person you are!”

Aomame said, “I’m a very ordinary human being. I just happen to like reading books. Especially history books.”

“I like history books too. They teach us that we are basically the same, whether now or in the old days. There may be a few differences in clothing and lifestyle, but there’s not that much difference in what we think and do. Human beings are ultimately nothing but carriers—passageways—for genes. They ride us into the ground like racehorses from generation to generation. Genes don’t think about what constitutes good or evil. They don’t care whether we are happy or unhappy. We’re just a means to an end for them. The only thing they think about is what is most efficient for them.”

“In spite of that, we can’t help but think about what is good and what is evil. Is that what you’re saying?”

The dowager nodded. “Exactly. People have to think about those things. But genes are what control the basis for how we live. Naturally, a contradiction arises,” she said with a smile.

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth.

The order of fossils in the world’s rocks is powerful evidence of our connections to the rest of life.

Do the facts of our ancient history mean that humans are not special or unique among living creatures? Of course not. In fact, knowing something about the deep origins of humanity only adds to the remarkable fact of our existence: all of our extraordinary capabilities arose from basic components that evolved in ancient fish and other creatures. From common parts came a very unique construction. We are not separate from the rest of the living world; we are part of it down to our bones and, as we will see shortly, even our genes.
