| Resumo: | The horse, Equus, has long enjoyed a k-ind of pre-eminence in the eyes of biologists. So instructive and apparently well-documented are the facts of its evolution that a discussion of them is a part of most elementary courses in zoology. Several decades of students have beeil taught that the horse finds its origin in the Eocene with the rise of the humble forest-dweller Eohip pus. This cat-sized animal of browzing habit was dramatically transformed into modern Equus through a series of increases in body size and changes in teeth and legs adapting it for a cursorial, grazing existence. These adaptations followed known changes in the Tertiary landscape from moist woodland to dry grassland. |
