Evolution ... Is Opportunistic, Hence Unpredictable.

I Feel That One Species, Mankind, Doesn't Have The Right To Exterminate

A Species Is A Reproductive Community Of Populations Reproductively Isolated From Others That Occupies A Specific Niche In Nature.

Evolution Thus Is Merely Contingent On Certain Processes Articulated By Darwin: Variation And Selection.

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.

It Seems To Me That For Darwin The Pulsing Of Evolutionary Rates Was A Strictly Vertical Phenomenon.
