Hominin adaptations in the Lesser Sunda Islands: exploring the vertebrate record to investigate fauna diversity before, during and after the Last Glacial Maximum

This paper reviews the available vertebrate record from the Lesser Sunda Islands to explore the effect the Last Glacial Maximum had on human subsistence strategies. By focusing on vertebrate assemblages from Laili and Matja Kuru 2 in Timor Leste, Tron Bon Lei in Alor Island, and Here Sorot Entapa in Kisar, this paper investigates biodiversity and resource availability in these nearby islands through the application of standardising indices and statistical testing. Results indicate that vertebrate biodiversity remained fairly stable through and after the Last Glacial Maximum, suggesting that in terms of available mammals, birds and reptiles, this period did not led to severe resource depletion. Hence, potential variations in human subsistence practices or occupation dynamics might not be due to changes in vertebrate diversity. As such, this analysis contributes to investigating anatomically modern humans' subsistence adaptation in the Lesser Sunda Islands pre- and post-Last Glacial Maximum.
