Trivia/same one as zebra
[[Evolution|Evolutionary]] biologists believe that the modern horse has slowly evolved into its present form over the course of about 60 million years, from ''Hyracotherium'' (60 million years ago) to our "modern-day horse," ''Equus'' (1 million years ago). This claim is based on various pieces of fossil evidence arranged in an apparent evolutionary pattern, such as the change from five toes on ''Hyracotherium'' (some vestigial) to three toes on ''Mesohippus'' and then to the single toe of ''Equus'' along with the progressing development of hooves. The skulls also shows an evolutionary trend from fossil to fossil, as do the teeth changing from a browser to a grazer.<ref>[http://chem.tufts.edu/science/evolution/HorseEvolution.htm Horse Evolution] from Tufts University</ref>

Medical school professors routinely tell their students, "If you hear hoof beats in Texas, think horses not zebras." This is to illustrate that when diagnosing a patient think of the more common diseases rather than rare exotic ones.
