Wallacea, the zone of oceanic islands separating the continental regions of Southeast Asia and Australia, has yielded sparse evidence for the symbolic culture of early modern humans. Here we report evidence for symbolic activity 30,000–22,000 y ago at Leang Bulu Bettue, a cave and rock-shelter site on the Wallacean island of Sulawesi. We describe hitherto undocumented practices of personal ornamentation and portable art, alongside evidence for pigment processing and use in deposits that are the same age as dated rock art in the surrounding karst region. Previously, assemblages of multiple and diverse types of Pleistocene “symbolic” artifacts were entirely unknown from this region. The Leang Bulu Bettue assemblage provides insight into the complexity and diversification of modern human culture during a key period in the global dispersal of our species. It also shows that early inhabitants of Sulawesi fashioned ornaments from body parts of endemic animals, suggesting modern humans integrated exotic faunas and other novel resources into their symbolic world as they colonized the biogeographically unique regions southeast of continental Eurasia.

Much remains unknown about the population history of early modern humans in southeast Asia, where the archaeological record is sparse and the tropical climate is inimical to the preservation of ancient human DNA1. So far, only two low-coverage pre-Neolithic human genomes have been sequenced from this region. Both are from mainland Hòabìnhian hunter-gatherer sites: Pha Faen in Laos, dated to 7939–7751 calibrated years before present (yr cal bp; present taken as ad 1950), and Gua Cha in Malaysia (4.4–4.2 kyr cal bp)1. Here we report, to our knowledge, the first ancient human genome from Wallacea, the oceanic island zone between the Sunda Shelf (comprising mainland southeast Asia and the continental islands of western Indonesia) and Pleistocene Sahul (Australia–New Guinea). We extracted DNA from the petrous bone of a young female hunter-gatherer buried 7.3–7.2 kyr cal bp at the limestone cave of Leang Panninge2 in South Sulawesi, Indonesia. Genetic analyses show that this pre-Neolithic forager, who is associated with the ‘Toalean’ technocomplex3,4, shares most genetic drift and morphological similarities with present-day Papuan and Indigenous Australian groups, yet represents a previously unknown divergent human lineage that branched off around the time of the split between these populations approximately 37,000 years ago5. We also describe Denisovan and deep Asian-related ancestries in the Leang Panninge genome, and infer their large-scale displacement from the region today.

This paper presents a reassessment of the archaeological record at Leang Burung 2, a key early human occupation site in the Late Pleistocene of Southeast Asia. Excavated originally by Ian Glover in 1975, this limestone rock-shelter in the Maros karsts of Sulawesi, Indonesia, has long held significance in our understanding of early human dispersals into ‘Wallacea’, the vast zone of oceanic islands between continental Asia and Australia. We present new stratigraphic information and dating evidence from Leang Burung 2 collected during the course of our excavations at this site in 2007 and 2011–13. Our findings suggest that the classic Late Pleistocene modern human occupation sequence identified previously at Leang Burung 2, and proposed to span around 31,000 to 19,000 conventional 14C years BP (~35–24 ka cal BP), may actually represent an amalgam of reworked archaeological materials. Sources for cultural materials of mixed ages comprise breccias from the rear wall of the rock-shelter–remnants of older, eroded deposits dated to 35–23 ka cal BP–and cultural remains of early Holocene antiquity. Below the upper levels affected by the mass loss of Late Pleistocene deposits, our deep-trench excavations uncovered evidence for an earlier hominin presence at the site. These findings include fossils of now-extinct proboscideans and other ‘megafauna’ in stratified context, as well as a cobble-based stone artifact technology comparable to that produced by late Middle Pleistocene hominins elsewhere on Sulawesi.

The Preneolithic Stone Artefact of Leang Jarie Site: The Oldest Evidence of Maros Point  Technology in the Toalean Culture Region, South Sulawesi. Maros Point is one type of flake tool that shows characteristics of the techno-complex Toalean from South Sulawesi. Early emergence of the Toalean Culture phase is still debated, but most experts agree that this tool only appeared no more than 4000 years ago and is positioned include with pottery or Neolithic period. The Maros Point is considered to be made by the early occupants of Sulawesi after the arrival and contact with Austronesian speakers migration in South Sulawesi. The problem is that the results of the latest research are contrary to previous opinions. This paper aims to show new evidence of excavation at the Leang Jarie Site, as the oldest Maros Point technology ca. 8,000 years ago in the Toalean Cultural Region. Maros Point is made simpler with the support flake without using reduction pattern of flake-blade technology. Flakes with an asymmetrical shape can also be utilized as long as it have a pointed and thin tip. The "backed" retouched technique is also used to maximize flakes with steep sharp edges. Thus, the phase of Toalean Culture compiled by previous studies needs to be reviewed and the presence of Maros Points can no longer be used as a marker of the youngest phase. Maros Point is produced from the early holocene or Preneolithic Period and has possibility its continuation until Neolithic period.Maros Point adalah salah satu tipe alat serpih yang menunjukkan karakteristik teknokompleks budaya Toalean dari Sulawesi Selatan. Awal munculnya masih diperdebatkan. Namun, sebagian besar ahli sepakat bahwa alat ini baru muncul tidak lebih dari 4.000 tahun yang lalu dan diposisikan sekonteks dengan tembikar atau masa neolitik. Maros Point dianggap dibuat oleh penghuni awal Sulawesi setelah kedatangan dan kontak dengan migrasi penutur Austronesia di Sulawesi Selatan. Permasalahannya adalah hasil penelitian terbaru justru bertentangan dengan pendapat sebelumnya. Tulisan ini bertujuan untuk menunjukkan bukti baru dari penggalian di situs  Leang Jarie, sebagai teknologi Maros Point paling tua berumur ca. 8.000 tahun lalu di kawasan budaya Toalean. Maros Point dari masa preneolitik dibuat lebih sederhana dengan dukungan serpih tanpa harus menggunakan pola penyerpihan teknologi serpih bilah. Serpih dengan bentuk yang tidak simetris pun dapat dimanfaatkan selama memiliki ujung runcing dan tipis. Teknik peretusan “dipunggungkan” juga digunakan untuk memaksimal serpih dengan tepian tajaman yang terjal. Dengan demikian, fase budaya Toalean yang disusun oleh penelitian sebelumnya perlu ditinjau ulang dan kehadiran Maros Point tidak bisa lagi dijadikan sebagai penanda fase paling muda. Maros Point diproduksi dari awal holosen atau preneolitik dan mungkin terus berlanjut hingga masa neolitik.

Major gaps remain in our knowledge of the early history of Homo sapiens in Wallacea. By 70–60 thousand years ago (ka), modern humans appear to have entered this distinct biogeographical zone between continental Asia and Australia. Despite this, there are relatively few Late Pleistocene sites attributed to our species in Wallacea. H. sapiens fossil remains are also rare. Previously, only one island in Wallacea (Alor in the southeastern part of the archipelago) had yielded skeletal evidence for pre-Holocene modern humans. Here we report on the first Pleistocene human skeletal remains from the largest Wallacean island, Sulawesi. The recovered elements consist of a nearly complete palate and frontal process of a modern human right maxilla excavated from Leang Bulu Bettue in the southwestern peninsula of the island. Dated by several different methods to between 25 and 16 ka, the maxilla belongs to an elderly individual of unknown age and sex, with small teeth (only M1 to M3 are extant) that exhibit severe occlusal wear and related dental pathologies. The dental wear pattern is unusual. This fragmentary specimen, though largely undiagnostic with regards to morphological affinity, provides the only direct insight we currently have from the fossil record into the identity of the Late Pleistocene people of Sulawesi.
