Question 1

The fundamental idea behind parsimony is

Accepted Answer

A) that the best phylogeny is the one that both explains the observed character data and posits the fewest evolutionary changes. 
B) to provide a second approach to inferring phylogenetic relationships. 
C) to compute the number of morphological or molecular differences between two or more species or populations. 
D) that morphological traits cannot be used to reconstruct phylogenetic history.

Question 6

Using the evidence presented in the three figures above,describe how combining phylogeographic evidence-including geological processes such as continental drift,natural history (including distribution and dispersal of species),and phylogenies-worked to develop a hypothesis supporting the common ancestry of ratite birds.(Hint: Ratite birds are flightless,and tinamous can fly only weakly.)
