This evolutionary tree shows the influence of speciation and extinction on the diversity of life. After 2 million years, lineage A had a(n) rate of extinction and speciation rates compared to lineage B.

Lower; higher

Explanation: Speciation is a term used to describe the formation of new, distinct and diverse set of characters and organism as evolution occurs in lineages of an organism.

The higher the number of lineages the higher the number of diverse characters and features. That is what makes the speciation to be lower in the chances of extinction to be higher as the lineages Increase from lineage 1 to lineage 2.
