Drawn observed several different types of finches. Why are there so many different types?

Finches live in different places, but eat the same food.

Finches live in the same place, but eat different types of food.

Finches live in different habitats and eat different types of food.

Finches are found all over the world.

The differences among a species, like different bird beaks, are called

genes.

variations.

traits.

theories.

Organisms with the most beneficial traits will survive. This is commonly known as

theory of evolution.

variations.

survival of the fittest.

ecosystems.

This scientist developed the theory of evolution as he studied the finches.

Charles Darwin

Isaac Newton

Albert Einstein

Marie Curie

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

Variation

Adaptation

Behavior

Environment

Where the better adapted organisms survive to pass traits along to offspring.

Evolution

Natural Selection

Extinction

Artifical Selection

What are the most studied animals in the galapagos?

Finches

Tortoises

Turtles

Lizards

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.

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

10.

Do organisms "decide" to evolve and change?

Yes, they know they need to change to survive

No, they change because of natural selection

11.

Which of the following describes what is meant by Natural Selection?

An organism will survive no matter what its adaptations may be

An organism with adaptations that do not allow it to reproduce as effectively as others will survive.

An organism with adaptations that allow it to obtain resources and reproduce more effectively than others will survive.

No organisms will survive.

12.

Which best describes an adaptation?

A trait that helps an organism to survive in its environment.

A trait that the organism can change when he wants.

A trait that does not help the organism to survive in its environment.

The place where an organism lives.

13.

What does the term variation mean?

The same traits in a population.

The different ways that traits are expressed in a population.

The same ways traits are expressed in a population.

The place where an animal lives.

14.

Animals are born with their adaptations due to genes.

True

False

15.

Animals are able to pick and choose their adaptations.

True

False

16.

Mutations are a source of variations.

True

False

17.

Variations are differences between individuals in a population.

True

False

18.

Over time natural selection can change how often a trait is seen within a population.

True

False

19.

Before the industrial revolution the birds were eating more black moths. After the industrial revolution the birds started eating more white moths. Why

The birds thought the white moths tasted better.

There were not any black moths to eat

The white moths stood out on the dark trees so the birds could see them easier.
