The answer would be: <span>A. Mitochondrial DNA is beneficial in both of these cases

Mitochondrial DNA or mtDNA is DNA that found in the mitochondrial. Mitochondrial DNA only inherited from mother, so it's relatively unchanged than nuclear DNA that mixed from father and mother.
Mitochondrial DNA has higher mutation rate in animals because it doesn't have repair mechanism like nuclear DNA. These mutations can be used as a clue for how close the relation of an organism to others.
This makes analyzing the ancestral relationship of organisms that closely or distantly related easier.

Pioneer species are the first organisms to live in an area
Some examples of a pioneer are:
•bunch grass
•milkweed
•queen Anne’s lace
•Sphagnum moss
•sedge
•pitcher plant
Answer:
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Explanation:
Divergent evolution is when two different species share the same ancestral origins but have evolved differently whereas convergent evolution is when species with different ancestral origins have developed similar features.
In convergent evolution, two species that are not necessarily closely related develop similar features often as a result of adaptation to similar conditions.
