Textbook Question
Chapter 13, Problem 4AQ
Imagine that you have discovered a new form of microbial life one that appears to represent a fourth domain. How would you go about characterizing the new organism and determining if it actually is evolutionarity distinct from Bacteria, Archaea, and Eukarya?

All of the following statements are true about the3-domain classification system EXCEPT:(a) The three domains are Bacteria, Archaea, and Eukarya.(b) Lateral gene transfer has forced us to rethink our do-main model from a “tree of life” to a “shrub of life.”(c) Domains are higher than the category of kingdoms.(d) Compared to Bacteria, Archaea inhabit the same en-virons and have the same amount of peptidoglycan intheir cell walls.(e) All of the above are true.
Why were Archaea originally thought to be simply unusual forms of Bacteria? What lines of evidence showed this domain to form a distinct branch on the tree of life?
Choose one prokaryote (bacteria or archaea) AND one protest. You can choose a species or more general taxonomic group of interest. Then address the following questions for each.
1. What does the organism look like? Describe or include an image.
2. How does it obtain energy?
3. How does it reproduce?
4. What are its close relatives in the tree of life?
5. Why is it important from a human perspective?

Domains The six-kingdom system didn't show that all four eukaryote kingdoms are more closely related to each other than to the two bacteria kingdoms. It also didn't show that the two bacteria kingdoms are as different from each other as they are from the eukaryote kingdoms. To show these similarities and differences, a new taxon, called the domain, was introduced. It was defined as a taxon higher than the kingdom. The Three-Domain System In 1990, a new classification system was introduced that contained three domains: Bacteria, Archaea, and Eukarya. The Bacteria domain was formerly the Eubacteria kingdom, and the Archaea domain was formerly the Archaebacteria kingdom. The Eukarya domain includes all four eukaryote kingdoms: plants, animals, protists, and fungi. The three-domain system emphasizes the similarities among eukaryotes and the differences among eukaryotes, bacteria, and archaea. By using domains, these…arrow_forwardSelect the choice that identifies the organism described in the following statement: The organism is heterotrophic, has cells with cell walls, and is a eukaryote.
