Patrick Matthew (1790–1874) regarded natural selection as a force of conformity. Competition between species kept them from dysmorphic chaos. Catastrophes exterminated many species that would otherwise compete. The absence of this competitive natur

While Joseph Hooker was considering his upcoming presentation on the geographical distribution of species, he asked Charles Darwin for help with some references. During the ensuing exchange of correspondence, Darwin seems to have contradicted himself

A historical episode of evolutionary theory, which has lead to the Red Queen theory of the evolutionary maintenance of sex, includes two striking contingencies. These are used to explore alternative what-if scenarios, in order to test some common opi

I consider the motives of historians devising counterfactual histories, analyze the narrative structure of these histories, and assess their merits. Richard Evans attacked counterfactual histories as motivated by wishful thinking. And he claimed that

Since intelligent design (ID) advocates claimed the ubiquitous mouse trap as an example of systems that cannot have evolved, mouse trap history is doubly relevant to studying material culture. On the one hand, debunking ID claims about mouse traps an
