2. Both have similarities in their teeth structures. Their structures indicates that they are herbivores. Herbivore animals eat grass and other plants.
They lack canines, thus cannot eat meat. They have flat and wide teeth that are adapted to chew plants.
These structures are common on both sides and thus are called as homologous structures.
3. They both have antlers, and in both organisms some females do not have antlers.
4. They both have four-chambered stomachs. They also have hooved toes. These characteristics also indicates that they both are herbivores.
