Which best sums up the relationship between microevolution and macroevolution?

Microevolution occurs through or as a result of macroevolution; it is the outcome of macroevolution operating over long time scales at high levels of organization.

A swarm of insects blows out to sea in a storm. They arrive at a tiny island and form a new population. After many generations, they have diverged from the source population on the mainland. The result is an island-specific (endemic) species with a close relative on the mainland. This is an example of ____________.

mutation

allopatric speciation

sympatric speciation

A rare (fictitious) plant species, the Frilly Philodendron, contains a chemical that is helpful in controlling cancer. Biologists would like to find similar chemical compounds and test them for potential medical use. Which would be the most efficient strategy for finding these chemicals?

Base your search on ecology. Look in other plants that live in the same specific habitat with the Frilly Philodendron. In particular, examine all the plants that grow in the same soil type, because they will probably have similar chemistry.

Do a phylogenetic analysis and then look in plants that are closely related to the Frilly Philodendron. They will probably produce similar chemical compounds.

Base your search on geography. Look in other plants that live in the same region as the Frilly Philodendron. They should have similar chemistry because they are exposed to similar climate.
