Question

what do fossils reveal about the evolution of the horse? select all that apply a they were as tall as they are today b older fossils show that early horses were about the size of a fox, and they had four long toes. c horse ancestors lived in wooded marshlands. d their teeth were pointed

Explanation:

• Option a: Modern horses are taller than their early ancestors, so a is incorrect.
• Option b: Fossil evidence shows early horses (like Eohippus) were fox - sized and had multiple toes (four long toes - like structures), so b is correct.
• Option c: Horse ancestors lived in wooded, marshy environments, and fossils along with paleo - environmental evidence support this, so c is correct.
• Option d: Early horse ancestors had teeth adapted for browsing (not pointed like for carnivory; they were herbivores with more complex tooth structures for plants), so d is incorrect.

Answer:

b. Older fossils show that early horses were about the size of a fox, and they had four long toes.
c. Horse ancestors lived in wooded marshlands.
