Outgroup analysis looks for features that are shared derived characters in a give n group of organısms. a. True b. False A paraphyletic group consists of several evolutionary lines that do not share a common ancestor. a. True b. False Systematists use phylogenetic trees to graphically represent hypothesized evolutionary relationships among ganisms. a. True b. False A characteristic that is independently acquired by reversal or convergent evolution exhibits homology. a. True b. False Mammalia is a class the contains many phyla. a. True b. False Two organisms with similar features should always be grouped together. Why or why not. How do cladists classify a new species, and how does it differ from a classification based on phonetics?

The features that are shared in a group of organisms are looked at in an outgroup analysis. This statement is true. A paraphyletic group is made up of several evolutionary lines that do not share a common ancestor. There is a statement that is true. A paraphyletic group is a group of organisms that include an ancestors but not all of their descendants. The phylogenic tree is used by systematists to represent the evolutionary relationships among organisms. The above statement is not false. The phylogenic tree is also referred to as the evoutionary tree.
