Question

Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. Which observation that he made about finches most supports that hypothesis?
The finches all ate the same materials as the mainland population.
The finches were all relatively small compared to the mainland population.
The finches all appeared to be related but differed from the mainland population.
The finches were identical to the mainland population.

Answer 1

Answer;

C. The finches all appeared to be related but differed from the mainland population.

Explanation;

-The basic idea of biological evolution is that populations and species of organisms change over time. Darwin proposed that species evolve and that all living things can trace their descent to a common ancestor.

-He suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them. Moreover, he noted that each finch species was well-suited for its environment and role.

Answer 2

The answer to this question is C. The finches all appeared to be related but differed from the mainland population.
