In fact, death seems to have been a rather late invention in evolution. One can go a long way in evolution before encountering an authentic corpse.

Evolution advances, not by a priori design, but by the selection of what works best out of whatever choices offer. We are the products of editing, rather than of authorship.
Interpretation
Evolution is driven by natural selection rather than predetermined design, highlighting our development through adaptation and selection.
George Wald's quote emphasizes that evolution occurs not from a premeditated design but rather through the process of natural selection, where organisms that adapt best to their environments are favored. This concept underscores the idea that we are shaped by the outcomes of various choices and circumstances rather than being crafted with a specific plan in mind, illustrating the randomness and complexity of life's development.
In practice
In a biology class discussing the principles of evolution.
In fact, death seems to have been a rather late invention in evolution. One can go a long way in evolution before encountering an authentic corpse.
I have lived much of my life among molecules. They are good company. I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!
Our challenge is to give what account we can of what becomes of life in the solar system, this corner of the universe that is our home; and, most of all, what becomes of men-all men, of all nations, colors, and creeds. This has become one world, a world for all men. It is only such a world that can now offer us life, and the chance to go on.
Nuclear weapons offer us nothing but a balance of terror, and a balance of terror is still terror.
I think if a physician wrote on a death certificate that old age was the cause of death, he'd be thrown out of the union. There is always some final event, some failure of an organ, some last attack of pneumonia, that finishes off a life. No one dies of old age.
Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind.
Unless a price can be put on carbon emissions that is high enough to force power companies and manufacturers to reduce their fossil-fuel use, there seems to be little chance of avoiding hugely damaging temperature increases
When I left NASA, I was looking at how you could use space technologies for developing countries' work.
Science is a way of thinking much more than it is a body of knowledge.
There are people who could watch a hurricane like Sandy blow out of the Atlantic every other day and blame it on anything but human activity. They are like those who, having been diagnosed with diabetes, eat donuts for breakfast. There's not much to do about them.
Some 5 billion years from now, there will be a last perfect day on Earth... then the sun will begin to die, life will be extinguished, the oceans will boil and evaporate away.
It will free man from the remaining chains, the chains of gravity which still tie him to this planet.
