Ancient Indians called the native inhabitants of the Nicobar Islands as नारिकेलद्वीपवासी or “Coconut Island Dwellers” Their example was used in philosophy to describe a kind of people who had no idea about farming & didn’t even know what a cow looked like.
At that time in India, it was also considered that South Indians were as unacquainted with the camel as these people were with the cow.
The person on the right belongs to the Shompen tribe of the Nicobar Islands. They are a Mongoloid people, rather than a Negrito type.
It is fascinating how these tribes never went extinct despite Indians knowing of them for millenia. Maharajadhiraja Rajendra Chola even built a naval base on the Andaman Islands. Yet within 2 centuries of first contact by the eternal Anglo, these people are nearly extinct.
