I Feel That One Species, Mankind, Doesn't

In Neither His Definition Nor The Examples Illustrating What Memes Are Does Dawkins Mention Anything That Would Distinguish Memes From Concepts.

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.

In Those Early Years In New York When I Was A Stranger In A Big City, It Was The Companionship And Later Friendship Which I Was Offered In The Linnean Society That Was The Most Important Thing In My Life.

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

The Reduced Variability Of Small Populations Is Not Always Due To Accidental Gene Loss, But Sometimes To The Fact That The Entire Population Was Started By A Single Pair Or By A Single Fertilized Female. These 'founders' Of The Population Carried With Them Only A Very Small Proportion Of The Variability Of The Parent Population. This 'founder' Principle Sometimes Explains Even The Uniformity Of Rather Large Populations, Particularly If They Are Well Isolated And Near The Borders Of The Range Of The Species.
