The Great Andamanese is one of the most ancient people groups, a collection of 10 tribes tracing their lineage directly back to the first people who migrated out of Africa. These tribes have slowly dwindled over the past few centuries. One of the tribes had only one survivor remaining, Boa Sr.—a woman with no children and failing eyesight. After Boa’s husband died, she was no longer able to speak to anyone in her native language (Bo).
