On his trip to the galapagos islands, darwin determined that animals on the islands a. had changed through biogeography b. were unlike any animals in the world c. looked like animals in south america d. were identical to animals in england

The answer is: C.looked like animals in South America

Despite the similarities, there are  a couple of differences in physical attributes among the animals in Galapagos island and the animals in south America.

From this, Darwin created an assumption that the animals in both areas originally come from the same ancestral. But over time, the animals experienced an evolution to adapt to environment around them , which caused the difference in physical attributes.
