In Figure 2 a diagram shows how traits are shared (or not shared) in different generations. Based on the diagram:
a. A, represents a plesiomorph trait. In how many generations is A shared (symplesiomorph)?
b. C represents an apomorphictrait. What generations share C (synapomorphy)?
c. E is considered an autapomorphic trait. Why do you think?
d. What about B and D? How do we classify them?
Which of the following is not correct?

D.
Bilateral symmetry in the frog and the snapdragon flower is homoplasious
E.
The dorsal fin of a shark and the dorsal fin of a dolphin are homologous.
Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related?
A.
Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous.
B.
Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease.
C.
The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins.
D.
All prokaryotes and eukaryotes use DNA to carry their genetic information.

- Traditionally morphological features are used to construct phylogenic trees of related species. In recent years, molecular sequences of nucleic acids or proteins, called the "molecular clock” by some researchers, have been used to reveal phylogenic relations.

What statement about the differences of the two phylogenic trees is accurate? A. The common ancestors of Carnivora/Rodentia and Chiroptera/Primates are the same for tree A; they are different for tree B. B.
