Evolution Thus Is Merely Contingent On Certain

Definitions Are Temporary Verbalizations Of Concepts, And Concepts- Particularly Difficult Concepts- Are Usually Revised Repeatedly As Our Knowledge And Understanding Grows.

Indeed, I Was Unable To Find Any Evidence Whatsoever Of The Occurrence Of A Drastic Evolutionary Acceleration And Genetic Reconstruction In Widespread, Populous Species.

I Had Found Again And Again That The Most Aberrant Population Of A Species - Often Having Reached Species Rank, And Occasionally Classified Even As A Separate Genus - Occurred At A Peripheral Location, Indeed Usually At The Most Isolated Peripheral Location.

The Major Novelty Of My Theory Was Its Claim That The Most Rapid Evolutionary Change Does Not Occur In Widespread, Populous Species, As Claimed By Most Geneticists, But In Small Founder Populations.

According To The Concept Of Transformational Evolution, First Clearly Articulated By Lamarck, Evolution Consists Of The Gradual Transformation Of Organisms From One Condition Of Existence To Another.
