Actually, horses did not evolve at all. God is the Creator of everything, and He made everything (including animals and humans) to never change. In other words, nothing has evolved and there IS NO PROOF THAT EVOLUTION IS REAL!!!! But I actually DO have proof that evolution is NOT real. So sorry....no one can answer that question.
Horses that run faster don't get caught, so faster horses are more common now than in the early stages.
Nij means that horses that run faster than predators live longer to reproduce more and raise colts that can run faster.
They might have had evolution (Obviously)
But probably because of how their surroundings were and where they lived which probably either changed or they moved to a diffrent place, they adapted to that form of survival, for example they adapted to eating grass so over time they evolved into a bigger head and diffrent teeth, and for running their hoofs once had 4 toes and they eventually evolved into a single toed hoof which is better for running.

The evolution of the horse demonstrates how horses have evolved over time. This evolution is theorized to be caused by the changing of terrain and climate.
No adaptation, no survival. Hence: Darwinism, evolution, survival of the fittest.
Organisms are not isolated in their environment. Organisms must interact with other individuals of their own species, with other species, and with their physical environment. The study of the interactions between organisms and their environment is called ecology (Greek: oikos- house; logia- study). The study of ecology can encompass all aspects of Biology; from physiology to behavior, because any change within an organism has the potential to affect its relationship with the environment.
An organism's environment is everything that surrounds it.
There is no rate to evolution. Evolution is simply the following of natural selection within an environment. natural selection is like survival of the fittest. A mutation in the organism is caused which can start the natural selection process for that organism. If that organism is able to survive better with that mutation then the trait is passed down and slowly evolution takes place. The only way for evolution to happen at the same rate of another organism is if the organisms rely on each other and one goes through a change. The other dependent species will have to also go through an alteration in order to be able to survive. hope this helps!
Convergent Evolution is the reason. :)
it's ecology
The relationship among an organism's environment, adaptations and evolution is that the environment will alter, so the organism has to adapt to the new environment. Throughout the years this has created evolution seen in fossils and history books

ecology /ecological evolution.
at the core of every organism's interaction with the environment is its need for energy to power life's processes.energy to power life's processes.
An ecological niche is the role that an organism plays in its environment, included in that is it habitat and the interactions it has with other organisms in that environment.
Biology, in its simplest form, is the large branch of science concerned with the study of life. Also it studies the interactions of organism with the abiotic environment and each other.

Ecologists Study the Interactions of Organisms and Their Environment. ... In its life and reproduction, every organism is shaped by, and in turn shapes, its environment. Ecological scientists study organism-environment interactions across ecosystems of all sizes, ranging from microbial communities to the Earth as a whole.
