Evidence of Evolution and Natural Selection

The change in traits over time in a population is known as

• Evolution

• Mutation

• Selection

• Traits

Body parts of organisms that are the same in structure and position but different in function and shared by a common ancestor.

• embryos

• homologous structures

• analogous structures

• vestigial structures

Body parts that have lost their original function.

• embryos

• homologous structures

• analogous structures

• vestigial structures

Two organisms that are closely related would have

• Very similar DNA sequences

• Very different DNA sequences

• The same exact DNA sequences

• No similarity in DNA

Images of the embryo and adult stages of three different organisms are shown.

Which of the following is the best conclusion that can be drawn from this evidence?

• Having similar embryos indicates that these organisms eat the same types of food.

• Having similar embryos indicates that these organisms share a recent common ancestor.

• Having similar embryos indicates that these organisms live in a similar environment.

• Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?

• There were different types of predators on the islands.

• The finches on the mainland could not fly high enough.

• There was no water on the islands.

• There were different food types on each island.

New traits (genetic variation) comes from

• Random Mutations

• The environment

• Adaptations

• Animals choosing new traits

• Predators

• Selection

If a new trait DOES NOT help an organism survive, what may happen to it?

• Not survive or reproduce

• Survive & reproduce

• Survive

• Die

Body parts that function like each other, but are different in structure and NOT shared by common ancestor

• embryos

• homologous structures

• analogous structures

• vestigial structures
