Certainly paleontologists have found samples of an extremely small fraction, only, of the earth's extinct species, and even for groups that are most readily preserved and found as fossils they can never expect to find more than a fraction. ”

Almost all paleontologists recognize that the discovery of a complete transition is in any case unlikely. ”

He is a state of matter, a form of life, a sort of animal, and a species of the Order Primates, akin nearly or remotely to all of life and indeed to all that is material. ”

Now we do have many examples of transitional sequences. ”

Most of the dogmatic religions have exhibited a perverse talent for taking the wrong side on the most important concepts in the material universe, from the structure of the solar system to the origin of man. ”

Recognition of this kinship with the rest of the universe is necessary for understanding him, but his essential nature is defined by qualities found nowhere else, not by those he has in common with apes, fishes, trees, fire, or anything other than himself. ”

Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms. ”

I have a debt, a loyalty to the museum; the best place for me to do what I wanted to do. ”

Every paleontologist knows that most new species, genera, and families, and that nearly all categories above the level of family appear in the record suddenly and are not led up to by known, gradual, completely continuous transitional sequences. ”

Of course the orders all converge backward in time, to different degrees. ”
