J. O. Corliss explained that the original title given to the Workshop (namely, the phylogeny and evolution of the protozoa) seemed out of date, since today we clearly cannot persist in separating various protozoa from many of the algae and from certain zoosporic fungi by erection of formidable taxonomic barriers at the phylum (division) or kingdom level. All such forms, the species of which are being discovered to be inextricably comingled at various levels (for the latest extensive review, see Corliss, 1984), are perhaps better assigned to a single kingdom Protista or to several kingdoms predominantly containing these ‘lower’ eukaryotes (see subsequent sections of this report, below).
