Scientists rightly resist invoking the supernatural in scientific explanations for fear of committing a god-of-the-gaps fallacy (the fallacy of using God as a stop-gap for ignorance). Yet without some restriction on the use of chance, scientists are in danger of committing a logically equivalent fallacy-one we may call the “chance-of-the-gaps fallacy.” Chance, like God, can become a stop-gap for ignorance. ↗
Darwin, with his Origin of Species, his theories about Natural Selection, the Survival of the Fittest, and the influence of environment, shed a flood of light upon the great problems of plant and animal life. These things had been guessed, prophesied, asserted, hinted by many others, but Darwin, with infinite patience, with perfect care and candor, found the facts, fulfilled the prophecies, and demonstrated the truth of the guesses, hints and assertions. He was, in my judgment, the keenest observer, the best judge of the meaning and value of a fact, the greatest Naturalist the world has produced. The theological view began to look small and mean. Spencer gave his theory of evolution and sustained it by countless facts. He stood at a great height, and with the eyes of a philosopher, a profound thinker, surveyed the world. He has influenced the thought of the wisest. Theology looked more absurd than ever. Huxley entered the lists for Darwin. No man ever had a sharper sword -- a better shield. He challenged the world. The great theologians and the small scientists -- those who had more courage than sense, accepted the challenge. Their poor bodies were carried away by their friends. Huxley had intelligence, industry, genius, and the courage to express his thought. He was absolutely loyal to what he thought was truth. Without prejudice and without fear, he followed the footsteps of life from the lowest to the highest forms. Theology looked smaller still. Haeckel began at the simplest cell, went from change to change -- from form to form -- followed the line of development, the path of life, until he reached the human race. It was all natural. There had been no interference from without. I read the works of these great men -- of many others – and became convinced that they were right, and that all the theologians -- all the believers in "special creation" were absolutely wrong. The Garden of Eden faded away, Adam and Eve fell back to dust, the snake crawled into the grass, and Jehovah became a miserable myth. ↗
Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a mammal or to convert a fish into an amphibian. Microevolution looks at adaptations that concern the survival of the fittest, not the arrival of the fittest... The origin of species — Darwin’s problem — remains unsolved. ↗

Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us. ↗
[...] we have in our treatise a series of fifty-seven examinations, almost exclusively of injuries of the human body forming a group of observations furnishing us with the earliest known nucleus of fact regarding the anatomy, physiology and pathology of the human body. Crude and elementary as they are, the method by which they were collected was scientific, and these observations, together with the diagnoses and the explanatory commentary in the ancient glosses, form the oldest body of science now extant. ↗

Constrained optimization is the art of compromise between conflicting objectives. This is what design is all about. To find fault with biological design - as Stephen Jay Gould regularly does - because it misses some idealized optimum is therefore gratuitous. Not knowing the objectives of the designer, Gould is in no position to say whether the designer has proposed a faulty compromise among those objectives. ↗

Every single cell in the human body replaces itself over a period of seven years. That means there's not even the smallest part of you now that was part of you seven years ago. ↗
