Jonathan Weiner Quotes

The rapid accumulation of change is not always progress, and forward motion is not always an advance.

Why are there so many kinds of animals? Adaptive radiations like Darwin’s finches are the essence of the answer.

We are doing what the dinosaurs did before us, only faster. We bring strangers together to make strange bedfellows, and we remake the beds they lie in, all at once.

Geneticists will tell you that. Evolution is always happening. What they mean is that the genes of this generation are not precisely what they were the preceding generation. Nor will they be precisely the same in the next. And evolution is that change.

Philosophers used to ask whether we are born with or invent our sense of time. Now we know that we have clocks woven into every one of our cells. Philosophers also used to ask how we know that the sun will rise tomorrow. In a sense we have that answer built into us, too. The clock is a kind of orrery in the heart of every one of our cells, revolving to help us keep time with our world, a model of the cosmos inside our heads that cycles whether we are in or out of sight of the sun. The revolution of the stars and the seasons is written in the turns of our DNA.

Taken together, these new studies suggest that Darwin did not know the strength of his own theory. He vastly underestimated the power of natural selection. Its action is neither rare nor slow. It leads to evolution daily and hourly, all around us, and we can watch.

All three spoke in the kind of down-home, common-as-flies style that is the lingua franca of great scientists, conveying a contempt for pretension, a contempt for cant, a delight in common sense, combined with uncommon curiosity about what is really there.

“Our only real competition for domination of the planet remains the viruses,” the microbiologist Joshua Lederberg once said. “The survival of humanity,” he added, “is not preordained.”

Some people seem to think that behavior is behavior only when it is a mystery, Hall continued. But once any piece of behavior is understood at the molecular level, it all comes down to metabolism, whether we are talking about the way a weaver ant folds a leaf, a weaverbird weaves a hanging nest, a human being learns and speaks Swahili, or a fly rises with the dawn and settles down at dusk. “Benzer was once subjected, in my earshot,” Hall said, “to some dumb question like ‘Is that the mind or the brain?’ But every aspect of mind and brain is ultimately metabolism! What do we think? Some kind of electric aura hovers around our heads?” We still seem to want something outside the mechanism, Hall said, some deus ex machina to save us from the clockwork that we have been exploring above and inside our heads for the last several centuries. It is now time for us to accept that behavior is as much a part of the material world as the stars above us and the atoms inside us. All behavior turns on molecular clockwork, Hall said, yet all behavior is fascinating.

The pamphlet teaches the skills that skills that Benzer’s former labmates would now need to learn, including propaganda, “that branch of lying which consists in very nearly deceiving your friends without quite deceiving your enemies.”

People who don’t believe in relativity don’t understand relativity. People who don’t believe in evolution don’t understand evolution. And it’s the same with genetics. And I think some people are just reluctant to let their imaginations run.
My feeling is that molecular biologists are going to move into psychology and take over the field. I think that’s the way psychology is going to be rejuvenated.

For all species, including our own, the true figure of life is a perching bird, a passerine, alert and nervous in every part, ready to dart off in an instant. Life is always poised for flight. From a distance it looks still, silhouetted against the bright sky or the dark ground; but up close it is flitting this way and that, as if displaying to the world at every moment its perpetual readiness to take off in any of a thousand directions.

Whether or not we choose to watch, evolution is shaping us all.

All times seem special to those who live in them.

Evolution discloses a meaning in death, although the meaning is like some of the berries that Darwin tasted in the Galapagos, “acid & Austere.” There is a special providence in the fall of a sparrow. Even Drought bears fruit. Even death is a seed.
