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.
1. A cladogram is a diagram that shows the evolutionary relationships among groups of .
2. The point where two branches diverge on a cladogram represents a .
3. Organisms that are more closely related on a cladogram share a more recent .
1. Briefly explain the difference between an ancestral trait and a derived trait.
2. How does a cladogram help scientists understand the process of evolution?
1. All organisms on a cladogram evolved from a single common ancestor.
True
False
2. Cladograms always show the exact time of evolutionary divergence.
True
False
