“By the mid-1980s, [Stephen Jay Gould] had emerged as a major public figure, using his background as a paleontologist to dive into controversies with radical stances on the ways new species emerge and how evolutionary change comes about.

This audience proved an ideal focal group for Gould to try out his new theories and presentations. Every Tuesday and Thursday in the fall he held forth, lecturing with dramatic flourish to undergraduates who either sat rapt in the front rows or sprawled sleeping in the rear ones.” EvolutionPopular ScienceMotivated ReasoningStephen Jay Gould Book:Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA Source: Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA
