Question
Chapter 23, Problem 1IQ
Summary Introduction
To determine: The limited number of character states and high rates of evolutionary change can cause problems for parsimony analyses.
Introduction: The smallest assumptions or change in characters in a state is known parsimony. Parsinomony analysis is complete opposite of homoplasy as it involves multiple characters into count. The homoplasy leads to the increase of relatedness between unrelated species.

Why would a slowly evolving gene have limited utility in dating recent divergences?
Why are proportional differences in fitness most relevant for evolution rather than absolute differences?
Does the use of DNA sequences in the study of evolutionary relationships mean that other characteristics are unimportant in such studies? Discuss what other forms of evidence you may still want to use, along with when and why those other forms of evidence would be especially helpful.
