How did horses change when evolved?
The line leading from Eohippus to the modern horse exhibits the following evolutionary trends: increase in size, reduction in the number of hooves, loss of the footpads, lengthening of the legs, fusion of the independent bones of the lower legs, elongation of the muzzle, increase in the size and complexity of the brain …
What evidence is there for evolution in horses?
Evidence from Fossils The fossil record reveals how horses evolved. The lineage that led to modern horses (Equus) grew taller over time (from the 0.4 m Hyracotherium in early Eocene to the 1.6 m Equus). This lineage also developed longer molar teeth and the degeneration of the outer phalanges on the feet.
What caused horses to evolve?
Forest changed into grassland with shrubs, similar to steppes or prairies. Adapting and reacting to the changing environment, the then living horses changed too. They became larger (Mesohippus was about the size of a goat) and grew longer legs: they could run faster.
What type of evolution is the horse?

Why are horses a good example of evolution?
“Horses are a very good example because there is a long, continuous fossil sequence of horses extending 55 million years in North America, providing the tangible evidence to trace individual steps or changes in evolution over a prolonged period of time,” he said.
How did the environment affect the evolution of horses?
“According to the classic view, horses would have evolved faster in when grasslands appeared, developing teeth that were more resistant to the stronger wear that comes with a grass-dominated diet.
