Gradual genetic development is often represented as a tree similar to the one shown in the diagram.
This diagram suggests that
a
biochemical differences show that no two organisms could ever have had a common ancestor.
b
different groups of organisms may have similar characteristics because of common ancestry.
c
only the most well-adapted organisms will survive.
d
speciation is a predictable event that happens every few years.

The correct answer is:
b different groups of organisms may have similar characteristics because of common ancestry.
This representation of gradual genetic development as a tree suggests that various organisms can share similar traits due to their descent from a common ancestor.
