Final answer:
Today's horses are descended from a wide variety of ancient horses through evolution and domestication.
Step-by-step explanation:
The statement is true. Today's horses are indeed descended from a wide variety of ancient horses. The evolution and domestication of horses is a fascinating topic. Ancient horses, such as the Eohippus, went through various stages of evolution over millions of years, eventually giving rise to the modern-day horses we see today.
For example, the Przewalski's horse is considered the closest living ancestor to the domesticated horse. It is a wild horse native to the Asian steppes and shares common ancestry with the domesticated horse.
Through selective breeding and domestication by humans, different horse breeds with specific characteristics and functions have been developed, ranging from racing horses to work horses.
