Question

Here is a phylogeny (i.e., a tree depicting evolutionary relationships) for three species of animal (a dog, a lizard, and a frog). Using the characters listed below, you'll have to figure out which animal goes on each branch (branches are labeled A, B, C). The characters are listed in the left column, and the primitive condition for each character is given under the column "ancestral condition". Assume that character transformations along the tree can only go one way (e.g., you can "gain" a tail, but you can't "lose" one) and that all shared traits are homologous.

Explanation / Answer
