1. What is the synapomorhpy shared by the mouse and chimpanzee?
Answer:
2. Specify the apomorphy of the pigeon.
Answer:
3. Jaw is present to what taxa?
Answer:
5. 5. Draw a phylogeny the following taxa: shark; tuna; frog; lizard; mouse; whale. On your phylogeny label the first occurrence/evolution of the following traits: cartilaginous skeleton; bony skeleton; hair; four limbs; shelled eggs. Describe a synapomorphy using any of the traits you labeled on the tree.
Draw a phylogenetic reconstruction for the hypothetical frog species. Once you have a cladogram you feel confident about, use lines and labels on cladogram to indicate where character states hanged. How many evolutionary changes occurred in your phylogeny? Is there evidence of an evolutionary convergence having occurred in your phylogeny? How about evolutionary reversals?
