Genetic evidence for anatomically modern humans (AMH) out of Africa before 75 thousand years ago (ka) and in island southeast Asia (ISEA) before 60 ka (93–61 ka) predates accepted archaeological records of occupation in the region. Claims that AMH arrived in ISEA before 60 ka (ref. 4) have been supported only by equivocal or non-skeletal evidence. AMH evidence from this period is rare and lacks robust chronologies owing to a lack of direct dating applications, poor preservation and/or…

The age of early AMH fossils from five caves in this region using ancient DNA analysis and a multimethod geological dating strategy was found to be much younger than previously suggested, with some remains dating to the Holocene owing to the complex depositional history at these subtropical caves.

Last appearance of Homo erectus at Ngandong, Java, 117,000–108,000 years ago

Bayesian modelling of radiometric age estimates provides a robust chronology for Homo erectus at Ngandong, confirming that this site currently represents the last known occurrence of this long-lived species.

Rare Late Pleistocene-early Holocene human mandibles from the Niah Caves (Sarawak, Borneo)

The results of direct Uranium-series dating and the first published descriptions of three partial human mandibles from the West Mouth of the Niah Caves are presented, suggesting a long history back to before the LGM of economic strategies involving the exploitation of raw plant foods or perhaps dried and stored meat resources.

A Middle Pleistocene Denisovan molar from the Annamite Chain of northern Laos

The Pleistocene presence of the genus Homo in continental Southeast Asia is primarily evidenced by a sparse stone tool record and rare human remains. Here we report a Middle Pleistocene hominin

Speleological and environmental history of Lida Ajer cave, western Sumatra

Some of the earliest evidence for the presence of modern humans in rainforests has come from the fossil deposits of Lida Ajer in Sumatra. Two human teeth from this cave were estimated to be 73–63

A multi-proxy approach to exploring Homo sapiens’ arrival, environments and adaptations in Southeast Asia

It is argued that this climate-driven shift offered new foraging opportunities for hominins in a novel rainforest environment and was most likely a key factor in the settlement and dispersal of the authors' species during MIS 4 in SE Asia.

Multiple hominin dispersals into Southwest Asia over the past 400,000 years

These findings reveal at least five hominin expansions into the Arabian interior, coinciding with brief ‘green’ windows of reduced aridity approximately 400, 300, 200, 130–75 and 55 thousand years ago, and reveal the tempo and character of climatically modulated windows for dispersal and admixture.



Archaeology and age of a new hominin from Flores in eastern Indonesia

Dating by radiocarbon, luminescence, uranium-series and electron spin resonance methods indicates that H. floresiensis existed from before 38,000 years ago (kyr) until at least 18 kyr, and originated from an early dispersal of Homo erectus that reached Flores and then survived on this island refuge until relatively recently.

The earliest unequivocally modern humans in southern China

This study shows that fully modern morphologies were present in southern China 30,000–70,000 years earlier than in the Levant and Europe, and supports the hypothesis that during the same period, southern China was inhabited by more derived populations than central and northern China.

U-series and radiocarbon analyses of human and faunal remains from Wajak, Indonesia.

The Age of the 20 Meter Solo River Terrace, Java, Indonesia and the Survival of Homo erectus in Asia

The age of the sites and hominins is at least bracketed between these estimates and is older than currently accepted, and may favor an African origin for recent humans who would overlap with H. erectus in time and space.

Prehistoric teeth of man and of the orang-utan from Central Sumatra, with notes on the fossil orang-utan from Java and Southern China

The evolution of the dentition of Pongo pygmaeus (Hoppius) is described, which shows how man's natural interest in his nearest relatives has built up an enormous interest in the living anthropoids.

Evaluating the usefulness of enamel thickness and microstructure as characteristics for determining the relationships of the later Miocene hominoids is evaluated, based both on a quantitative study ofEnamel thickness in extant hominoid and four species of laterMiocene Sivapithecus (including ‘Ramapitalcus’) and on scanning electron microscope analysis of enameling microst structure.
