The story of ISEP
The formation of a society concerned with early events in eukaryotic evolution was discussed by Lynn Margulis, Max Taylor and Howard Whisler in Seattle, USA, in late 1973, following the First International Congress of Systematic and Evolutionary Biology in Boulder, USA, where the SET (serial endosymbiosis theory) had its first formal discussion and a protistan session was also held.
It was formally proposed, with election of an ad hoc editorial committee, at a meeting on the origin and evolution of mitosis in Boston, USA, in 1974 (see Margulis & Taylor, 1975), and this has been taken as the first Society for Evolutionary Protistology (SEP) meeting. The second, convened in Toronto, Canada, was summarized by Heath (1978). The word ‘International’ was added after the fourth meeting, held in Maryland, USA (see Goode & Corliss, 1981, 1982), and the society was formally incorporated in 1982.
