Evolution Test

According to natural selection organisms with greater fitness pass their genes onto the next generation at a higher rate than other organisms. In evolutionary terms, great fitness refers to organisms _____________.

• Surviving Longer

• Reproducing more

• Being physically stronger

Which statement best describes the process of evolution?

• Populations can survive in different locations on earth

• Environmental conditions limit the number of species on Earth

• Populations grow when resources are abundant

• The traits of a species can change over time

Modern whales developed their traits through natural selection. What occurs during the process of natural

selection?

• Organisms choose mates from other species to create new species

• Breeders selectively cross organisms with desired traits

• Only the fittest organisms can survive and reproduce

• Organisms remain exactly the same over time

Which of these would be considered an adaptation of an animal that lives in the snowy tundra?

• A thick coat of fur & blubber

• Large, flat feet

• Green colored skin

• Webbed feet

A whale uses its fin for a different function than a cat uses its paw. However,, the bone structure of the whale’s fin and the cat’s paw are the same because they both came from a recent common ancestor. This is an example of what kind of structures?

• Evolution Structures

• Homologous Structures

• Vestigial Structures

Refer to the scenario described in question 5. The gills of the catfish and shark are an example of what kind of structures?

(SAME FUNCTION, DIFFERENT STRUCTURE)

• Homologous Structures

• Analogous structures

• Vestigial Structures

• Evolution strucutres

Humans no longer have any use for their wisdom teeth. Even so, in our evolutionary history we once used our wisdom teeth for greater jaw strength. Wisdom teeth are an example of what kind of structure?

• Analogous Structure

• Homologous Structure

• Vestigial Structures

The structures shown are_________

• homologous
• heterologous
• analogous
• vestigial

Descent with modification, one of Charles Darwin’s two main ideas on evolution, states that all living organisms _________________?

• Came from spontaneous generation

• Came from past organisms and have changed over time

• Have been the same since the beginning of time

Which best explains why the birds evolved with differently shaped beaks?

• They interbred with each other.

• Some birds had defective gene pools.

• All of the birds ate the same type of food.

• They adapted to eating different types of food.
