Evolution As Such Is No Longer A

There Are A Number Of Attributes Of Species And Populations That Are Not Of Any Particular Selective Advantage To Any Single Individual In A Population But That Are Of Great Advantage To The Population As A Whole.

A Species Consists Of A Group Of Populations Which Replace Each Other Geographically Or Ecologically And Of Which The Neighboring Ones Integrate Or Hybridise Wherever They Are In Contact Or Which Are Potentially Capable Of Doing So (with One Or More Of The Populations) In Those Cases Where Contact Is Prevented By Geographical Or Ecological Barriers.

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

To Take An Unequivocal Stand, It Seems To Me, Is Of Greater Heuristic Value And Far More Likely To Stimulate Constructive Criticism Than To Evade The Issue.

Isolating Mechanisms Are Biological Properties Of Individuals That Prevent The Interbreeding Of Populations That Are Actually Or Potentially Sympatric.
