This Has Had The Unfortunate Consequence That The Theory Of Natural Selection Itself Has Scarcely Ever, If Ever, Received Separate Consideration.

Modern Statisticians Are Familiar With The Notion That Any Finite Body Of Data Contains Only A Limited Amount Of Information On Any Point Under Examination; That This Limit Is Set By The Nature Of The Data Themselves, And Cannot Be Increased By Any Amount Of Ingenuity Expended In Their Statistical Examination: That The Statistician's Task, In Fact, Is Limited To The Extraction Of The Whole Of The Available Information On Any Particular Issue.
