Darwin's Finches

Darwin published his idea of natural selection which explained that

• species naturally go extinct

• species can adapt to their surroundings by choice

• Species have variations that give a competitive advantage and are passed on to offspring

• Species are the same and work together to survive

What is a common ancestor?

• An animal that has a lot of offspring.

• An animal from which two or more different species evolved.

• An animal that is related to many other species.

• An animal that's good at escaping from predators.

Nature has a way of causing organisms that inherit advantageous traits to survive and reproduce more successfully than the ones that don't. This process is known as...

• natural selection

• genetic variation

• adaptation

• overproduction

Darwin used the Galápagos finches as evidence that

• traits are not hereditary.

• living things change over time.

• birds are different than other species.

• organisms in a species have no relation to one another.
