Interesting that leftists are Darwinists. Yet they want the opposite in their politics.
Full title of his seminal work is: “On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life”.
Survival of the Unfit
Charles Darwins Theory of Evolution (often referred to as The Theory of Survival of the Fittest) describes the positive effects resulting from any pressure on an animal species that removes the least fit among the species and allows only the most fit of the species to reproduce. Many of us are well aware of this Survival of the Fittest theory, but few are aware that Darwin also makes mention of the negative effects resulting from unlimited reproduction of a species least fit when the weak, the lazy, and the stupid are left unchecked.
We like to think otherwise, but our species, Homo sapiens-sapiens, isnt that long out of the trees and the same laws of nature that affect all of Gods creatures apply equally to us. If we were to observe any other species that had been allowed to reproduce without limitations, we would know immediately what the consequences will be.
Whenever the weak; lazy; and stupid of a species are allowed to reproduce unimpeded by predators that feed off the weak; lazy; and stupid, they soon outnumber the strong, productive, and intelligent. When the weak/lazy/stupid dominate the gene pool, the entire population becomes weak/ lazy/stupid, and then the population collapses.
