ABSTRACT Wallacea is the transitional biogeographic zone between the continents of Sunda (Southeast Asia) and Sahul (Australian-New Guinea). It consists of a series of island chains unique in the region for never having been connected to either continent. Movement of early modern humans from Sunda to Sahul during the late Pleistocene required dispersal through Wallacea, and hence would have necessitated sea crossings. However, the archeological evidence for early modern humans in Wallacea is… 
Least-cost pathway models indicate northern human dispersal from Sunda to Sahul.
Mitogenomes Reveal Two Major Influxes of Papuan Ancestry across Wallacea Following the Last Glacial Maximum and Austronesian Contact
The results point to a surprisingly dynamic population history in Wallacea, marked by two periods of extensive demographic change concentrated around the Last Glacial Maximum ~15 ka and post-Austronesian contact ~3 ka.
Reconstructing Palaeogeography and Inter-island Visibility in the Wallacean Archipelago During the Likely Period of Sahul Colonization, 65–45 000 Years Ago
The palaeogeography of the Wallacea Archipelago is a significant factor in understanding early modern human colonization of Sahul (Australia and New Guinea), and models of colonization patterns, as
Introgression, hominin dispersal and megafaunal survival in Late Pleistocene Island Southeast Asia
It is proposed that this understudied region may hold the key to unlocking significant chapters in Denisovan prehistory and is highlighted as a potential signature of deep, pre-H.
Consequences of the Last Glacial Period on the Genetic Diversity of Southeast Asians
It is found that both the LGP and migration through LDD should be taken into consideration to explain the currently observed genetic diversity in these populations and supported a rapid expansion of first populations throughout SEA.
Hominin Dispersal and Settlement East of Huxley’s Line
The thousands of islands east of Huxley’s Line have never formed a single land mass or been connected to Sunda or Sahul. The earliest records of hominins in this area are stone tools recovered from
Coastal Subsistence Strategies and Mangrove Swamp Evolution at Bubog I Rockshelter (Ilin Island, Mindoro, Philippines) from the Late Pleistocene to the mid-Holocene
Abstract Subsistence adaptations to coastal environments and the capacity to take advantage of mangrove swamps has likely played an important role in the success of the maritime colonization of


The prehistory of Island Southeast Asia: A multidisciplinary review of recent research
Island Southeast Asia extends across both the equatorial and the intermediate tropical zones of world climate, and it also spans a region of complex and geologically unstable land and sea
The great arc of dispersal of modern humans: Africa to Australia
Stepping out: a computer simulation of hominid dispersal from Africa.
A computer simulation model of hominid dispersal is described which creates probability distributions for arrival dates at six key localities and compares these with current estimates from the archaeological and fossil records to support some of the current arguments about dispersal and to challenge others.
The Late Quaternary palaeogeography of mammal evolution in the Indonesian Archipelago
Assessment of the Southern Dispersal: GIS-Based Analyses of Potential Routes at Oxygen Isotopic Stage 4
This paper explores the geographic and environmental context of the Southern Dispersal Route, which has been proposed as a migratory route for Homo sapiens from East Africa to Australasia during
Dating the colonization of Sahul ( Pleistocene Australia – New Guinea ) : a review of recent research
The date for the initial colonization of Sahul is a key benchmark in human history and the topic of a long-running debate. Most analysts favor either a 40,000 BP or 60,000 BP arrival time, though
Southeast Asia’s changing palaeogeography

Plate tectonic movements and collisions were intimately linked to changing topography, bathymetry and land/sea distributions which have in turn influenced oceanic circulation and climate as the deep-water barrier between Australia and Southeast Asia was eliminated and mountains rose, deep marine basins also formed.
