What physical feature immediately identifies the Zebu cattle lineage?
Answer
A mass of fatty tissue supported by bone situated over the shoulders
The most immediate and distinctive identifier of the Zebu type is the prominent shoulder hump. This structure is composed of fatty tissue supported internally by bone structure situated directly above the shoulders. This trait is largely absent in the European cattle variety, *Bos taurus taurus*. While other morphological features like the dewlap and specific skin characteristics contribute to distinguishing Zebus, the hump is cited as the primary, readily observable physical marker that sets the Zebu grouping apart from other members of the *Bos* genus.
