Question
When Charles Darwin discovered the various finch species on the Galápagos islands, he was surprised to find so many different but related species in such a small geographic area. Which of the following best illustrates the correlation between competitive advantage and an individual’s traits in a particular environment?
-
Different islands had very different food
resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island. -
Finches had no natural predators on the island before Darwin’s voyage, allowing them to prosper on the islands.
-
Competition between different species for food resources led to resource partitioning of the ecosystem.
-
Mating behaviors in finch species ensure that different species of finch will not interbreed with one another.
