Fireside Conversation Sparked Storytelling

Day talk centered on practicalities and sanctioning gossip; firelit activities centered on conversations that evoked the imagination, helped people r...

If it is not, man has, or soon will have, the knowledge requisite to redirect the evolution of his species pretty much as he sees fit. Perhaps we should not be too dogmatic about this choice of direction. We may b...

 Natural Selection in Humans is Going Strong

The frequent allegation that the selective processes in the human species are no longer 'natural' is due to persistence of the obsolete nineteenth- century concept of 'natural' selection. The error of this view is made clear when we ask its proponents such questions as, why should the 'surviving fittest' be able to withstand cold and inclement weather without the benefit of fire and clothing? Is it not ludicrous to expect selection to make us good at defending ourselves against wild beasts wh...

 The History of Analogies Between Biological Evolution and...

Lewis Morgan's evolutionary theory of society included the three stages of savagery, barbarism, and civilization. The historian Arnold Toynbee used evolutionary ideas in identifying over thirty distinct ...
