Abstract
The review summarizes current evidence, including the findings related to molecular phylogeny of ciliates (type Ciliophora) and some related groups of protozoans. Based on comparison of the sequences of genes encoding various ribosomal RNAs (rRNAs), the phylogenetic relationships in seven out of eight known classes of ciliates are discussed. The events related to early branching of the eukaryotic tree are briefly presented. The evolutionary history of amitochondrial protists ids considered with regard to reductionistic evolution and archeozoic hypothesis. The phylogenetic relationships among ciliates and sister groups of apicomplexans and dinoflagellates are considered.
