What physiological system relates the Order Artiodactyla classification to a ruminant diet?

Answer

A complex, four-chambered stomach designed for efficient digestion of tough plant matter.

The placement of the white-tailed deer in the Order Artiodactyla is intrinsically linked to its dietary adaptations, reflecting its status as a highly specialized browser and ruminant. This evolutionary signature is supported by its complex, four-chambered stomach. This specialized organ structure is necessary to process and efficiently extract nutrients from the large volumes of fibrous, tough plant material that constitute its diet, distinguishing it from simpler herbivores or generalist grazers.
