Evolution

Cervinae is suggested to have split from Capreolinae at least 13.8 million years ago based on the first appearance of ''Euprox,'' suggested to be a stem-group cervine in Europe at this time. Modern Cervinae first appeared during the Late Miocene in Eastern Asia, arriving in the Indian subcontinent and Europe during the Early Pilocene. The ancestor of Cervinae probably had a bifurcated antlers similar to muntjacs, with the complex antlers of Cervini evolving independently from those of Capreolinae. Cervinae radiated during the Early Pleistocene, becoming the dominant group of deer across Eurasia.
