My first awareness of a motive for Adaptation and Natural Selection came during the 1954-55 academic year while on a teaching fellowship at the University of Chicago. The triggering event may have been a lecture by A.E. Emerson, a renowned ecologist and termite specialist. The lecture dealt with what Emerson termed beneficial death, an idea that included August Weismann’s theory that senescence was evolved to cull the old and impaired from populations so that fitter youthful individuals could take their places.
