Edward O Wilson, the pioneering Harvard biologist who advanced the provocative theory that human behavior such as war and altruism has a genetic basis and warned against the decline of ecosystems, has died. He was 92.

Wilson was “called ‘Darwin’s natural heir,’ and was known affectionately as ‘the ant man’ for his pioneering work as an entomologist,” according to an announcement posted Monday on the EO Wilson Biodiversity Foundation’s website. He died on Dec. 26 in Burlington, Massachusetts.
