“The Indonesian island of Sumatra is part of a chain of islands making up Sunda and the Malay Archipelago. Sumatra is one of the largest islands in the world, housing unique and globally important tropical rainforests, a diverse array of rare plants and magnificent animals, and a population of 60 million who speak a range of Austronesian languages. As beautifully exemplified in this volume, Sumatra is a place which preserves a distinct and long-term human history, studies of which began in earnest with Eugene Dubois’s explorations in the 1880s to find our ancestral ‘missing link’.
