What conclusion about the bacteria domain could be made from the phylogenetic tree below? the first branch of the phylogenetic tree holds the species of the bacteria division. It contains thermotoga bacteria, green non sulfur bacteria, cyanobacteria, gram positive bacteria, and purple bacteria. The second branch of the phylogenetic tree holds species of the eukarya. It contains diplomonads, microsporidia, trichomonads, flagellates, entamoeba, slime molds, ciliates, plants, animals, and fungi. The last branch of the phylogenetic tree starts at the beginning of eukarya line and holds the species of the archaea division. It contains thermococcus, pyrodictium, thermoproteus, methanobacterium, and extreme halophiles. Plants and animals evolved from the bacteria domain. Bacteria and eukarya are more similar than archaea and eukarya. Bacteria and archaea have similar evolutionary traits. Eukarya and bacteria developed on the same evolutionary line.

From the question, the ultimate branch of the phylogenetic tree starts with the line of Eukarya and then possesses the species of the Archaea division that comprises those prokaryotic species, which thrives in extremely tough environmental scenarios.

Now, as the last branch possesses species of two domains namely Eukarya and Archaea and it starts with Eukarya and afterward holds the species of Archaea, and that tells us that both Eukarya and Archaea are associated genetically.

In conclusion, what we can say about the bacteria domain is that Eukarya has similar evolutionary traits to Archaea.
