the horse is one of two extant subspecies of equus ferus.the horse is called equus ferus caballus.
Horses are such beautiful creatures. I enjoy riding them, but it's been awhile.
the horse has acually evolved over the past 45-55 millian years. it wa a small multi toed crature but now is a large single toed animal. thats impressive
Yes, it is. It's amazing how much people and animals have evolved. They were used for many other purposes besides recreation years ago, correct?
im not sure about what they were used for 45 million years ago but now their anatomy alows them to escape predators with speed and a high sense of balance. they have a strong fight or flight response
Yes, I was thinking more of around a couple of hundred years. When they were used for transportation and working the fields.
oh yes sorry yes of course. definitely used for transporation of goods and peple. horses in the subspecies caballus are domesticated though some domesticated populations live in the wild like feral horses.
Feral horses are so beautiful as well, but they sure have a strong sense of wildness and freedom. 
yeah. humans began to domesticate horses around 4k bc. their domestication is believed to have been widespread by as soon as 3k bc!
I never realized they had been around that long! That's surprising!
