I assume you mean Charles Darwin.
A collection of volcanic islands about 200 miles off the coast of Ecuador called the Galapagos Islands. Scrubby and wind swept though rather warm in climate.
The Galapagos Islands, which are about 600 miles off the coast of Ecuador.
The environmental challenge in the Grants' study was a severe drought that occurred in 1977 on the Galápagos Islands where they were studying finches. This drought caused a shortage of food, particularly the small seeds that the finches relied on for survival.
Certain species, and how they differed from one island to another; in this case, specifically, finches and tortoises.
That they were evoled from on specie of finches.
The Galapagos Islands.
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
The Galápagos Islands had finches that once shared a common ancestry. Darwin found that finches on one island had, over many generations, developed and adapted in differing ways to finches from other islands.
The finches that Peter and Rosemary Grant chose to study the Finches in the Galapagos because they are hybrid.
the animal Darwin examined were finches on the Galapagos islands (at least finches were the main thing he studied)

Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands
