Please create a phylogenetic (evolutionary) tree given this criteria and follow all points!
There are three domains of life - Bacteria, Archaea, and Eukarya.
Start by drawing these three main branches.
Then add branches for plants, animals, fungi, and protists. When adding all these branches,
don't just add them randomly. The branching pattern reflects evolutionary relationships. You
should use the relationships/branching patterns.
Then add additional branches for
• three species of bacteria
• three species of archaea
three species of plants
three species of animals
• three species of fungi
• three species of protists (single-celled eukaryotes)
You can pick any species you want. For each species, be sure to add 1 synapomorphy (shared
derived character) that defines the species or group.
•
Finally, label the tree with all the terms (parts of a tree, not phylogenetic groups) when
describing a phylogenetic tree.
Study the diagrams below. The diagrams represent four possible phylogenetic trees showing the
relationship between the four species: M, L, S, and R.

What is the plausible explanation for the appearance of autapomorphic character c in species L and S of
tree A although they do not share a most recent common ancestor?
Examine the following phylogenetic tree illustrated in Figure shown in the picture.
In general, what does a phylogenetic tree illustrate?
How do you compare the relationships of organisms BB, CC, and DD?

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…arrow_forwardStudy the sequences below.

- For novice biologists, taxonomy and phylogenetics are difficult concepts to understand and keep separate. This confusion is made worse because modern taxonomic methods make use of molecular tools. Write an essay that contrasts taxonomy to phylogenetics and explain how both disciplines are important to our understanding of species and evolution. Your essay should include a description of taxonomy and phylogenetics, as well as a detailed explanation about how information is represented in a phylogenetic tree or a cladogram.arrow_forwardfor the cactus (eukarotic) and the e coli bacteria (prokarotic) i want you to: Classify them based on modern taxonomy, and write their scientific name in three different ways based on Linnaeus.
