Boa Sr, who died last week aged about 85, was the last native of the Andaman Islands who was fluent in Bo.
Named after the tribe, Bo is one of the 10 Great Andamanese languages, which are thought to date back to the pre-Neolithic period when the earliest humans walked out of Africa.
Boa was the oldest member of the Great Andamanese, a group of tribes that are the the first descendants of early humans who migrated from Africa about 70,000 years ago and who arrived on the islands around 65,000. Other groups went on to colonise Indonesia and Australia.
