If the long-term extinction rate within lineage A is higher than that in lineage B and the long-term speciation rate in lineage B is higher than in lineage A, then we can conclude that
A) diversity of lineage A relative to diversity of lineage B will increase through time.
B) diversity of lineage A relative to diversity of lineage B will decrease through time.
C) lineage A will become increasingly diverse through time.
D) lineage B will become increasingly diverse through time.

Question

Quizplus · Accepted Answer

Lineage B will have a higher net diversification rate due to its higher speciation rate and lower extinction rate, leading to an increase in its diversity relative to lineage A over time.
