摘要: In the absence of a fossil record, evolution protozoa has until recently largely remained matter for speculation. However, advances in molecular methods and phylogenetic analysis are now allowing interpretation "history written genes". This review focuses on recent progress reconstruction trypanosome phylogeny based data from ribosomal RNA, miniexon protein-coding genes. Sufficient have been gathered to demonstrate unequivocally that trypanosomes monophyletic; trees derived can serve as framework reinterpret biology, taxonomy present day distribution species, providing insights into coevolution with their vertebrate hosts vectors. Different dating divergence lineages give rise radically different evolutionary scenarios these reviewed. particular, use one such biogeographically approach provides new pathogens, Trypanosoma brucei cruzi, human history diseases which they associated.
