2.
What was the main function of the horse before World War II?
Correct Answer
B. Used as a 'war machine'
Explanation
Horses were used mostly in wars: to carry soldiers, pull wagons with weapons and in the fight against the enemy.
3.
Horses had their beginning about 58 million years ago.
Correct Answer
A. True
Explanation
The given statement is true because scientific evidence suggests that the first known ancestor of the modern horse, called Eohippus or Hyracotherium, lived about 58 million years ago during the Eocene epoch. Fossil records and genetic studies support the evolution of horses over millions of years, with various species and adaptations occurring throughout their evolutionary history. Therefore, it is accurate to say that horses had their beginning around 58 million years ago.
4.
Which choice shows the stages of evolution of the horse?
Correct Answer
D. Eohippus; mesohippus; equus
Explanation
The correct answer is "eohippus; mesohippus; equus." This answer shows the correct order of the evolutionary stages of the horse. Eohippus is an early ancestor of the horse, followed by mesohippus, and finally equus, which is the modern horse.
5.
How tall was eohippus?
Correct Answer
B. 12 inches
Explanation
Eohippus, also known as the dawn horse, was approximately 12 inches tall. This prehistoric ancestor of modern horses lived during the Eocene epoch, around 50 million years ago. Its small size allowed it to navigate through dense forests and brush, and its low height was beneficial for evading predators.

Check all the boxes which describe Mesohippus:
Correct Answer(s)
A. 24 inches tall
C. Three toes on each foot
D. Long middle toe on each foot
G. Could run fast for long distances which helped it find food and water
Explanation
Mesohippus was a small horse-like animal that stood 24 inches tall. It had three toes on each foot, with a long middle toe. Unlike the statement that it was not able to run fast or long distances, Mesohippus was actually capable of running fast for long distances. This ability would have been beneficial for finding food and water in its environment.
8.
The species known as equus had its start in North America.
Correct Answer
A. True
Explanation
Equus is a genus of mammals that includes horses, donkeys, and zebras. Fossil evidence suggests that the earliest species of Equus originated in North America around 4 million years ago. These early equids then spread to other parts of the world, including Eurasia and Africa. Therefore, it is true to say that the species known as Equus had its start in North America.
9.
Equus escaped to Asia and Europe during the Ice Age by crossing:
Correct Answer
A. The land bridge between Alaska and Siberia called the Bering Strait
Explanation
During the Ice Age, when sea levels were lower, the land bridge between Alaska and Siberia called the Bering Strait was exposed. This allowed Equus to migrate from Asia to North America and vice versa. The Bering Strait acted as a bridge connecting the two continents, enabling the movement of various species, including Equus, across the landmass. This migration was possible due to the close proximity of Alaska and Siberia, making it a logical and feasible route for Equus to escape to Asia and Europe.
10.
Horses lived only in Asia and Europe until they were brought to America by the Spaniards in the 16th century.
Correct Answer
A. True
Explanation
Once equus crossed the land bridge to Central Asia and Europe, the species died out in what became North America.

Correct Answer
A. The Greek word "eos" meaning dawn
Explanation
The term "eohippus" comes from the Greek word "eos" meaning dawn. The prefix "eo-" means dawn or early, and "hippus" means horse. Therefore, "eohippus" refers to the early horse or the dawn horse.
