What does the figure suggest?

The hyracotherium is the same species as the modern horse.

Between 55 and 50 million years ago there weren't any animals that could be considered as related to horses.

The modern horse is related to other extinct species.

Horses appeared up to a million years ago and did not have any ancestors before that time.
