What defines the structural adaptation characterizing the Order Artiodactyla?
Answer
Bearing weight primarily on an even number of toes, usually two or four
The Order Artiodactyla specifically groups even-toed ungulates. This classification is based on the structure of the feet, where the animal's weight is predominantly supported by an even number of toes, most often the third and fourth digits. These animals are considered ungulates because they walk upon the very tips of these toes, which are encased in hard structures known as hooves. This morphology is an adaptation typically associated with cursorial or running lifestyles, allowing for efficient movement across open terrain like savannas. This contrasts significantly with odd-toed ungulates (Perissodactyla).
