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.

Death seems to have been a rather late invention in evolution. One can go a long way in evolution before encountering an authentic corpse.
Interpretation
The quote reflects on the concept of death as a recent development in the evolutionary process.
George Wald suggests that death is not an inherent part of life but rather a relatively recent aspect of evolution. He implies that for much of the evolutionary history, life may have existed in forms that did not have the same relationship with mortality, prompting reflection on the nature of life and death in the grand scheme of evolution.
In practice
This quote could be used in a discussion about the nature of life in a biology class.

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.
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.
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.
The most poetical thing in the world is not being sick.
There is a solitude, which each and every one of us has always carried with him, more inaccessible than the ice-cold mountains, more profound than the midnight sea; the solitude of self. Our inner being, which we call ourself, no eye nor touch of man or angel has ever pierced.
Enlightenment means taking full responsibility for your life.
Religious fanaticism and hatred are a world-devouring fire, whose violence none can quench.
The fable of Christ and his twelve apostles is a parody of the sun and the twelve signs of the Zodiac, copied from the ancient religions of the Eastern world. Every thing told of Christ has reference to the sun. His reported resurrection is at sunrise, and that on the first day of the week; that is, on the day anciently dedicated to the sun, and from thence called Sunday.
My effort should never be to undermine another's faith but to make him a better follower of his own faith.
