Darwin observed many finch species on the Galapagos Islands. To explain these observations, he proposed that each species evolved from the same common ancestor, which was a finch species that migrated to the islands from the mainland. What additional evidence did Darwin use to support his explanation? A. The finch populations were very numerous, and different species often bred with one another.
B. The finch species lived in different habitats on different islands, which isolated them from one another.
C. The finch species were distributed evenly among all of the islands, but did not interbreed.
D. The beaks of the finches were identical, allowing them to eat the same foods on any of the islands.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
