What is "capreolinae"

The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals. The Capreolinae are believed to have originated in the Late Miocene, between 7.7 and 11.5 million years ago, in central Asia.

Although this subfamily is called New World deer in English, it includes reindeer, (Eurasian) elk, and roe deer, all of which live in Eurasia.
