Senior Horse Bowl Team Study Questions: Horse Science

1.

What was the principle use of the horse before World War II?

A.

A war machine
B.

A beast of burden
C.

A means of recreation and escape for humans
D.

All of the above
E.

A and b

Correct Answer
A. A war machine

Explanation
Before World War II, the principle use of the horse was as a war machine. Horses were used extensively in warfare for transportation, cavalry charges, and pulling artillery. They played a crucial role in military operations, providing speed, agility, and mobility on the battlefield. Additionally, horses were used as beasts of burden, carrying heavy loads and pulling carts. While horses were also used for recreational purposes and provided an escape for humans, their primary use was in warfare.

2.

The horse had its beginning 58 million years ago.

A.

True
B.

False

Correct Answer
A. True

Explanation
The statement is true because the horse indeed had its beginning 58 million years ago. This refers to the origin and evolution of the horse species, which can be traced back to the Eocene epoch, around 58 million years ago. Fossil evidence and scientific research support this timeline, showing the gradual development and diversification of horses over millions of years. Therefore, it is accurate to say that the horse had its beginning 58 million years ago.

Choose the correct order of the stages of the horse through evolution:

A.

Equus; eohippus; mesohippus
B.

Mesohippus; eohippus; equine
C.

Eohippus; mesohippus; equine
D.

Eohippus; mesohippus; equus

Correct Answer
D. Eohippus; mesohippus; equus

Explanation
The correct order of the stages of the horse through evolution is eohippus; mesohippus; equus. This is because eohippus, also known as Hyracotherium, is considered the earliest ancestor of the modern horse. It was a small, dog-sized animal with multiple toes. Mesohippus came after eohippus and had fewer toes, with a more developed foot structure. Equus, the modern horse, evolved from mesohippus and is characterized by a single toe and a larger size.

From where did the horse originate?

A.

The Steppes of Russia
B.

The Great Plains of North America
C.

Ancient China
D.

Europe

Correct Answer
B. The Great Plains of North America

Explanation
The correct answer is the Great Plains of North America. The Great Plains of North America is the region where horses originated. Horses evolved in North America millions of years ago and then spread to other parts of the world. They became extinct in North America around 10,000 years ago but were reintroduced by European explorers and settlers. The vast grasslands of the Great Plains provided an ideal habitat for horses to thrive and multiply, making it their place of origin.

Check all the options that describe Eohippus:

A.

Measured about 12 inches high
B.

Had four toes on each front foot and three toes on each hind foot
C.

Had teeth suitable for grazing
D.

Was able to live in a forested and swampy environment

Correct Answer(s)
A. Measured about 12 inches high
B. Had four toes on each front foot and three toes on each hind foot
D. Was able to live in a forested and swampy environment

Explanation
Eohippus was a small horse-like animal that measured about 12 inches high. It had four toes on each front foot and three toes on each hind foot, which is a distinct characteristic of this species. Additionally, Eohippus was able to live in a forested and swampy environment, indicating its adaptability to different habitats.

Check all the options which describe Mesohippus:

A.

Measured at least 24 inches tall
B.

Measured at least 30 inches tall
C.

Had shorter legs and multiple toes on each foot
D.

Had longer legs with three toes on each foot

Correct Answer(s)
A. Measured at least 24 inches tall
D. Had longer legs with three toes on each foot

Explanation
Mesohippus is described as measuring at least 24 inches tall and having longer legs with three toes on each foot. This means that Mesohippus was a relatively tall animal and had longer legs compared to its body size. Additionally, it had three toes on each foot, which suggests that it was adapted for running and had a more advanced limb structure compared to its ancestors.

7.

Mesohippus developed teeth for grazing and greater speed and endurance for finding food and for protection.

A.

True
B.

False

Correct Answer
A. True

Explanation
Mesohippus, an extinct horse-like mammal, developed teeth for grazing, indicating a shift in its diet towards consuming grass or vegetation. This adaptation allowed Mesohippus to efficiently obtain food. Additionally, it developed greater speed and endurance, which would have been beneficial for both finding food and escaping predators. These adaptations suggest that Mesohippus evolved to thrive in open grassland environments, where grazing and running were advantageous survival strategies. Therefore, the statement that Mesohippus developed teeth for grazing and greater speed and endurance for finding food and protection is true.

8.

The characteristics of equus include:

A.

Development of five toes
B.

Ability to graze for forage
C.

Escaped across a land bridge to Asia during the Ice Age
D.

Continued development to the species we know today in Asia and Europe
E.

All of the above
F.

None of the above

Correct Answer
E. All of the above

Explanation
Equus is a genus of mammals that includes horses, donkeys, and zebras. The characteristics listed in the question are all true for equus. The development of five toes refers to the evolutionary history of equus, which originally had multiple toes but eventually evolved to have a single toe, which is the hoof. Equus is also known for its ability to graze for forage, meaning they primarily feed on grass and other vegetation. During the Ice Age, equus escaped across a land bridge to Asia, which allowed them to expand their range. Finally, equus continued to develop and evolve in Asia and Europe, leading to the species we know today. Therefore, the correct answer is "All of the above."

Rate this question:

9.

The land bridge that equus crossed during the Ice Age was located between what is now California and Russia.

A.

True
B.

False

Correct Answer
B. False

Explanation
The land bridge to Asia during the Ice Age was located in the Bering Straits, between Alaska and Siberia.
