Evidence for Evolution #1

When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?

• Selective breeding

• Natural Selection

• Cloning

• Evolution of all species

Which scientist visited the Galapagos Islands and came up with the theory of natural selection?

• Theodor Schwann

• Gregor Mendel

• Charles Darwin

• Rudolf Virchow

Scientists have collected millions of fossils of different organisms, and have developed a timeline of life on Earth. What do we call this?

• Mutation

• Natural Selection

• The theory of evolution

• Fossil Record

Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a link to a common ancestor?

• Adaptations

• Analogous Structures

• Homologous Structures

• Extinction

A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?

• An adaptation

• A response to a stimulus

• A mutation

• Evolution

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 island.

• There were different types of food available on the island.

• The finches had no water to drink.

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

When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called.....

• Fossils

• Extinction

• Meiosis

• Variations

What do we call a change in a species over time?

• Adaptation

• Evolution

• Extinction

• Environmental influences

The law of superposition states

• the oldest rock layer is on the top, the younger rock layer is on the bottom
• rock layers are always in sequence from oldest to youngest
• the youngest rock layer is on the bottom and the oldest is on the top
• the oldest layer is on the bottom and the youngest is on the top when it is undisturbed

What can help a scientist know the approximate age of bones?

• the soil it is found in
• the index fossils in the area
• the type of rock it is formed in
• absolute dating
