Peter and Rosemary Grant studied natural selection in Galápagos finches for more than 40 years; which species was the focus of their research?Multiple choice question.The greater ground finchThe medium ground finchThe cactus finchThe tree finch

Charles Darwin consulted John Gould about the birds that he had collected on the Galápagos Islands. Gould identified 13 distinct types of finches based on the birds'Multiple choice question.feet.wings.stomach contents.bills.

How did natural selection shape the evolution of finches on the Galápagos Islands?Multiple choice question.Several different bird species migrated from the mainland to the Galápagos Islands and occupied the habitats to which they were best suited.Birds that used their beaks to crack bigger seeds acquired larger beaks in their lifetime and passed this trait on to their offspring.Birds with different heritable differences were able to better survive and reproduce in different habitats.

Why did Darwin infer that finches on Galápagos islands had undergone evolution by natural selection?Multiple choice question.Because of the close correspondence between their beaks and their food.Because they all looked nearly identical.Because they were found on an island but not on the mainland.Because they had the same beaks regardless of their food source.

There are thirteen species of finches on the Galápagos Islands. These species must have originated from a few birds of the same species that made their way from South America over 500 miles of ocean.  This is an example of what?Group of answer choicesbiogeographyfossilsmutationnatural selection
