DNA sequence data for a diplomonad, a euglenid, a plant, and an unidentified protist suggest that the unidentified species is most closely related to the diplomonad. Further studies reveal that the unknown species has fully functional mitochondria. Based on these data, at what point on the phylogenetic tree in Figure 1 did the mystery protist’s lineage probably diverge from other eukaryote lineages? Explain.

The branch lengths in the tree are scaled by evolutionary/genetic distance, so not by time. In the plot on the right, the summed branch lengths going from the root to the tips of the trees are then plotted against the dates the tips were sampled. What can we conclude from these figures?

I am getting confused on how to read/label the parts of this specific phylogenetic tree as well. The layout is confusing and I am struggling to identify the branches and clades, and just where the root of the tree is.

What do you mean by domain archae? Explain it briefly.
The universal phylogenetic tree of life shows the divergence of Bacteria, Archaea, and Eukarya. Studies of Lokiarchaeota help to elucidate these relationships, but the first universal tree of life was constructed by Carl Woese using ribosomal RNA sequences. There are advantages to using different types of nucleic acid for different types of analyses. What is a specific advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic analysis compared with DNA sequences? ▸ View Available Hint(s) SSU rRNA sequences accumulate mutations more rapidly than protein-encoding DNA. SSU rRNA is frequently transferred through horizontal gene transfer, whereas DNA sequences are not. Primers are required in DNA sequence analysis, but not for SSU rRNA sequence analysis. Although PCR products can be visualized with SSU rRNA, this is not the case with other forms of nucleic acids. DNA sequences are too highly conserved to work well for sequence analysis; individual species are…
