Question

According to the phylogenetic tree, which domains are more genetically related?

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.

Answer 2

The answer depends on the interpretation and understanding of the phylogenetic trees. The image shows the rooted phylogenetic tree consisting of the various kinds of organisms. The rooting of the tree is done by looking at how closely two species are related to each other. The species within a larger branch or archae are more similar to each other than with the species of the eukarya branch. The distance between the different branches of the tree also indicate how different they are. Larger the distance, the less related they become.
