Although I found no support for the Eocene fossil dates, the two major freshwater colonization events probably occurred much earlier than previously thought—as early as the Paleocene for Cyclotella, followed by an Eocene origin for the cyclostephanoid lineage. Major transitions in dinoflagellate evolution unveiled by phylotranscriptomics. Transition from the hermaphrodite to dioecious state leads to a loss of at least half of the diversity. the sexually producing species. This important division provides ancestral phenotypic qualities to deﬁne the fungal kingdom, which is otherwise devoid of unifying traits (Richards, Leonard & Wideman, ). The 18S ribosomal RNA (rRNA) libraries revealed vertically stratified populations dominated by photosynthetic protists, with a cryptophyte dominating shallow major transitions in protists populations (ELB–6 m; WLB–10 m), a haptophyte occupying mid-depths (both lobes 13 m) and chlorophytes residing in the deepest layers (ELB– m; WLB– m) of the photic zone.

Other major groups of green major transitions in protists algae had been established by this time, but there were no land plants with vascular tissues until the mid-Silurian. Overall, the results of this thesis indicate that a) microbial major transitions in protists diversification is not an uncommon major transitions in protists process in nature, that b) microbial lake-population can harbor high genetic diversity, that c) marine-freshwater transitions are.
