The given diagrams elucidate the evolution process
of modern horse – from Eohippus to the horse we see today.
On an overall, the development of modern
horse took forty million years and four stages. The first diagram depicts eohippus
that appeared forty million years ago, it was smaller in size, and had four
fingers foot. In the next ten million years, eohippus transformed into Mesohippus,
which was slightly bigger than its predecessor; had short hair on the back of its neck. The noticeable change occurred
was in its foot structure where four fingers were replaced by three, and the
middle finger had a bulb.
The Merychippus appeared 15 million ago,
which was again bigger and had thicker hair and tail, with a larger foot, the
structure of toes also expanded in size.
The species of modern horse is the largest,
with a thick coat of hair and a tail. The anatomy of foot has witnessed drastic
changes, as toes have given way to a hoof, a complex foot structure.
The final stage in the evolution of the horse
is that of a modern horse. This species is largest in its lineage, which has a
thick coat of hair on the back of its
neck and a thick and long tail.
