How are *Bos taurus* cattle differentiated from *Bos indicus* cattle, a common point of scientific interest?
Answer
Bos indicus cattle are recognizable by their humps
A primary point of scientific observation used to differentiate between the two main domestic cattle species groups is the presence of a hump. The Welsh Black belongs to the taurine group, designated as Bos taurus, and typically lacks this feature. In contrast, Bos indicus, commonly known as zebu cattle, are externally recognizable due to the distinct presence of a hump on their backs. This morphological difference is a key characteristic used in the field to distinguish between the European/American derived taurine lines and the Asian derived indicine lines.
