Read each question carefully and answer to the best of your ability. Refer to the provided cladogram for questions when necessary.
Observe the cladogram below to answer the following questions:
1. Which organisms share the most recent common ancestor according to the cladogram?
A and B
B and C
C and D
D and E
2. A derived characteristic is a trait that:
Is present in the ancestral species only.
Evolved in the common ancestor of a group and is shared by its descendants.
Is independently evolved in different lineages.
Is lost during evolution.
