Question
Chapter 18.5, Problem 2MC
Summary Introduction
To analyze:
The features used by a biologist to classify organisms into supergroups apart from the molecular evidence.
Introduction:
All the creatures that have had a common ancestor are grouped as a supergroup. Because they are monophyletic. Supergroup is another taxonomic level that comes before the kingdom and after the domain. Supergroups are the level above phyla, which is another name for a group.

1. The taxonomic Supergroups of life are a work in progress which attempt to
hypothesize on the relatedness of life's major groups. Currently this phylogeny
includes a non-dichotomously branching clade with three different branches
connecting to one node. The clade that includes all three branches emerging from
the same node is known as
A) homeoplasiac traits. B) polytomic lineages. C) paraphyletic clade. D) polyphyletic clade
E) all of the above
1) How have scientists created the "tree of life"? Do you think that variations exist between these created trees?
2) What are the pros and cons to creating a "tree of life"?
3) When constructing this tree of life we can see many dead ends or organisms that we are unsure of their exact placement. Why is this?
4) Choose one species (either alive today or extinct) and describe its taxonomic classification. What traits or characteristics were used to classify this species into its current taxonomic classification? What other organisms are considered to be its closest relatives?
How do scientists infer common lineages of different organisms based on their structures?

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_forward
