Chapter

Evolutionary biologists have long debated whether speciation occurs grad ually or in response to massive catastrophes (Mayr 1982, Gould 2002). By mid-twentieth century the gradualists, buttressed by a mathematical synthesis of Darwinian selection and Mendelian genetics, prevailed, and the catas trophists, of various stripes, were professionally marginalized, going the way of the dinosaur. Speciation was now viewed as resulting from selectionist microevolution in response to incremental environmental challenges, a view best embodied by early earts in ecological and population genetics.
