Use the table below to construct a phylogenetic tree for a group of alien organisms
found on the planet Kepler 22B by the astronomer D. Liscious. Ph.D. The common
ancestor of all these organisms was green, silicon-based, with 2 legs, 4 dataports, 1
sex, and did not possess powered flight, x-ray vision, or interdimensional awareness.
Assume the hypothesis of parsimony is valid and that all taxa are extant except for
Taxon A, which is extinct. (10 pts)
You should draw your tree on a piece of paper. Then, take a photo of it, save as a
file, and upload it here. Please make sure your tree is neat and easy to read.

- Global climate change is expected to result in drastic changes in precipitation patterns. This might mean that, due to the rain shadow effect, the windward sides of mountains might be wetter, while the leeward sides of mountains might be drier.
