character change
http://www.talkorigins.org/faqs/horses/horse_evol.htmlhere is your answer :)----------------------------------------------------------------------------*there is a better answer*-The first horse was called a Hyracotherium, or originally called Eohippus. it didn't look like the horse that we know today, it had 4 toes on each foot and it stood about 10 inches tall- the second horse was called either Mesohippus , just a bit larger than Eohippus, they had longer legs and 3 toes instead of 4-Merychippus (see Mesohippus).....gradually the Earth's dense, wet forests became firm, grassy plains, and to avoid extinction, the early horses had changed to.....-the next horse was Pliohippus, it had large, flat grinding teeth for feeding on grass, and longer, stronger legs supported by hooves.- then came the last horse that we all know today, Equus caballus! by the end of the ice age, millions of wild horses that we could now recognize today, roamed Europe and Asia.-
yes
variatio brings about evolutionary change with in species as over millions of years the have to adapt to the ever changing habbitats. take the horse for example millions of years ago it used to have multiple toes.yet over millions of years it has evolved to only have one toe
The ladder must be stable before you climb it. Here it is used as an adjective. The horse is in the stable. Here it is used as a noun.
Herbivorous means eats plants. For example, the horse is a herbivorous animal.

Eohippus, meaning 'dawn horse' in Latin, is generally considered the oldest known evolutionary ancestor of today's modern horse.
The Eohippus, or Dawn Horse, has been extinct for thousands of years. This creature was the ancestor of modern equines.
The first horse, Eohippus, appeared in North America around one to two million years ago. This tiny animal, not much bigger than a cat, was the ancestor of all modern equines. Eohippus means "Dawn Horse".
Eohippus
Environmental factors don't just contribute - they are the cause of the evolution of a species. For example, the horse is descended from a dog-sized creature called the Eohippus, which had separate toes instead of hooves, etc. It's evolution towards the horse came about through an environmental change of some sort. Presumably, the more jungle-like terrain the Eohippus would have thrived in began to thin out, becoming more open plains. Without trees or bushes to hide in, the Eohippus would have been easier to prey on. The ability to outrun predators would have been favoured by natural selection over the ability to hide from them. As a result, the individual toes gradually became the hooves adapted to running very quickly that we can see today. The small organism would have evolved towards the powerful modern horse. But without that environmental change, the Eohippus would still be here today.
Evolution never happened so a horse has always looked like the horses we see today.

Hyracotherium is Genealogically recognised as the start of the horse Linage, it had 4 Hoofed toes on the front 2 feet and 3 hoofed toes on the back 2. Over millions of years of evolution they evolved into what we now call today's Modern Horse. Most of the Evolution is believed to have occurred on the North Hemisphere.
Eohippus .
Horses are originated from the dawn horse, Eohippus, also know as Mesohippus. Eohippus was a small, dog-sized creature with teeth made for browsing rather that grazing. It had many toes, unlike the modern horses.
The Eohippus horse was the firsthorse to help us!
