Question
Chapter 26.1, Problem 2CC
Summary Introduction
To test visual skills: Find the tree showing different evolutionary history.
Introduction:
Phylogenetic tree depicts hypothesis relationship between one group and other group of organism. The tree displays five group of organism in the tip of the branch. They are interrelated and known as taxa. Every branch point symbolizes a common ancestor from the evolutionary lineages.

Part 2: Interpreting your phylogeny
Use your phylogeny to answer the following questions in the spaces provided
1.
Does any character exhibit evolutionary convergence (i.e., homoplasy) on this
tree? If so, which one(s)?
Is live birth a derived or an ancestral feature?
2.
3.
If species A, B, and C were placed into their own genus based on the presence of
green eyes, would this group be monophyletic, paraphyletic, or polyphyletic?
If species D, E, F, and G were placed into their own genus based on the presence
of red eyes, would this group be monophyletic, paraphyletic, or polyphyletic?
If species F and G had green eyes, and you knew nothing about the ancestor of
the group, would green eyes be more likely to be a derived trait or an ancestral
trait?
4.
5.
Is any character trait on the tree an autapomorphy, meaning that it is derived but
not shared with any other taxa? If so, which one(s)? If not, write 'none.'
6.
PROCEDURE: Create a phylogenetic tree for the Kingdom Plantae.
Include each of the main phylums discussed in the lecture (examples:
Bryophytes, Gymnosperms, Angiosperms, etc.)
