Question

1. Draw the maximum parsimony tree based on the provided data set.

You can draw the tree electronically,

or draw it by hand and scan or photograph a copy—or use any other appropriate means you wish.  

2. How many homoplasies are in the tree? Give the nucleotide position number(s) and tell what character states were independently derived in which species.

3. Two major clades are revealed by the tree. List the species in each clade. What can you say in general about the geographic distribution of each clade?  

4. In cases where two species of Map Turtle occupy the same river system, are those species each other's nearest relatives? Considering their phylogeny and distribution, what speciation events (including such factors as migration, vicariance, etc.) would you predict led to the species found in these rivers and their current distributions?Data table.PNG
