Darwin's Voyage
These islands are where Charles Darwin observed variations in the characteristics of animals and plants that later led to his theories on evolution.
What are the Galapagos Islands?
The differences among individuals of a species are referred to as this.
A. Natural variation
B. Fitness
C. Natural selection
D. Adaptation
What is A. Natural Variation?
This is the definition of evolution in biological terms.

This is the list in order of the levels of classification, beginning with domain.
What is:
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
True or False? Humans are more evolved than an earthworm.
What is false? One type of organism cannot be more evolved than another type of organism.
This process produced the two different types of beaks shown. (see photo)
A. Artificial Selection
B. Natural Selection
C. Geographical Distribution
D. Inheritance of Acquired Traits
What is B. Natural Selection?
An inherited characteristic that increases an organism's ability to survive and reproduce in its specific environment is called this.
A. Vestigial organ
B. Adaptation
C. Speciation
D. Radiation
What is B. Adaptation?
This is the definition of an ecomorph.
Ecomorphs have similar characteristics and live in similar habitats, but have different genetics and are different species.
Organisms in the domain Eukarya must contain this.

I have a cell wall with peptidoglycan. What kingdom am I a part of?
What is Eubacteria?
In addition to observing living organisms, Darwin studied the preserved remains of these ancient organisms.

A. characteristics their parents acquired by use and disuse.
B. characteristics that plant and animal breeders value.
C. the greatest number of offspring.
D. variations best suited to the environment.
What is D. variations best suited to the environment?
These are 3 different types of isolation that can lead to the evolution of two separate species.
What is behavioral, geographic, or temporal.
The domain Eukarya contains these 4 kingdoms.
What are protista, fungi, plantae, and animalia?
An animal breeder would use this to produce cows that give more milk.
A. Overproduction
B. Genetic Isolation
C. Acquired Characteristics
D. Artificial Selection
What is D. Artificial Selection?

1. The world has a tremendous diversity of living things throughout a wide range of habitats.
2. Animal species can have different characteristics based on their habitats and available food sources.
3. Fossils of gigantic, extinct mammals.
4. Experienced an earthquake.
5. Seashells in mountains high above sea level.
6. Rock ledges that had once been beaches that gradually built up over time.
Which of the following phrases best describes the results of natural selection?
A. The natural variation found in all populations.
B. Unrelated species living in different locations.
C. Changes in the inherited characteristics of a population over time.
D. The struggle for existence undergone by all living things.
What is C. changes in the inherited characteristics of a population over time.

A. Fish's tailfin
B. Alligator's claws
C. Dog's front legs
D. Mosquito's wings
What is C. Dog's front legs?
Here are two of the different species of tortoises that Darwin observed on the Galapagos Islands (see photo). Using the concept of natural selection, explain how these two different species of tortoises could have evolved from a common ancestor.

These are 3 different types of evidence that support the theory of evolution.
What are:
Fossils, similarities in early development, similarities in body structure, DNA, and protein structure. (Answers may vary.)

What is a mouse?
The number and location of bones in many fossil vertebrates are similar to those in living vertebrates. Most biologists would probably explain this fact on the basis of this/these.
A. the struggle for existence
B. the inheritance of acquired traits
