evolution and Natural Selection

Individuals that are well adapted to their environment will survive and produce:

• Fewer mutations

• Stronger genes

• More offspring

• Better traits

You look at two species and see very similar DNA. What does this likely tell you?

• These are the same animal.

• These animals have a common ancestor.

• These animals are not likely related.

• These animals are likely becoming one species.

An inherited characteristic that increases an organisms ability to survive and reproduce in its specific environment is called a(n)

• vestigial structure

• speciation

• analogous structure

• adaptation

According to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:

• pass on to their offspring their newly acquired traits.

• are better adapted to their environment than others and will pass on those adaptations to future offspring.

• do not pass on newly acquired traits.

• produce fewer offspring than others in the same environment.

When every organism of a species has died.

• Evolution

• Natural Selection

• Extinction

• Artificial Selection

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

Which of the following is a term for a group of similar organisms that can reproduce fertile offspring?

• individual

• population

• species

• fossil

Natural selection

• process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest

• Humans select which animals live and die

• both 

• IDK

The finches on the Galapagos island were similar in form except for variations of their beaks. Darwin observed that these variations were useful for:

•  attracting a mate

•  defending territory

•  building nests

•  gathering food

Who was the naturalist that traveled the world to study plants and animals?

• Albert Einstein

• Charles Darwin

• Charles Barkley

• Isaac Newton
