Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.

The analysis of variance is not a mathematical theorem, but rather a convenient method of arranging the arithmetic.

I believe sanity and realism can be restored to the teaching of Mathematical Statistics most easily and directly by entrusting such teaching largely to men and women who have had personal experience of research in the Natural Sciences.

The more highly adapted an organism becomes, the less adaptable it is to any new change.

It was Darwin's chief contribution, not only to Biology but to the whole of natural science, to have brought to light a process by which contingencies a priori improbable, are given, in the process of time, an increasing probability, until it is their non-occurrence rather than their occurrence which becomes highly improbable.

Experimental observations are only experience carefully planned in advance, and designed to form a secure basis of new knowledge.

... the actual and physical conduct of an experiment must govern the statistical procedure of its interpretation.
