This branching tree diagram is most likely used to
represent the theory that suggests
a new species arise throughout time following
rounds of mass extinction.
b all species share a common ancestor and that
change occurs through time.
c speciation occurs very quickly with long
periods of no change in between.
d all species originated during the same period
and some have subsequently gone extinct.

B. all species share a common ancestor and that change occurs through time.

Explanation:

The branched tree diagram is widely used in biological studies to explain evolutionary and inheritance processes. When the tree diagram is applied to a group of living beings, it means that all living beings represented there have the same ancestor in common, which is represented at the base of the tree. From this common ancestor, new species have emerged that are represented by the branches of the tree.
