In the endosymbiont hypothesis, the host cell was initially believed to have developed a nucleus and other major characteristics of a eukaryotic cell before taking in the bacteria which in time became mitochondria. This explanation is mainly grounded on existence of early-branching lineages of eukaryote that lack mitochondria. However, an alternative view has gained more support after evolutionary remnants of mitochondria were found in these organisms, where the host cell was yet to evolve the intricacy of eukaryote when the endosymbiosis first began. In this research, we examined the amino acid sequences of mitochondrial Hsp70 found in Giardia intestinalis, Trichomonas vaginalis, and Vairimorpha necatrix from each of the three major amitochondriate lineages. Analyzing the sequences with apriori and decision tree algorithm, we will compare the data with the sequence of the mitochondriate Mus musculus, and therefore provide grounds to evaluate the scenarios of endosymbiosis.
