In biogeography, geodispersal is the erosion of barriers to gene flow and biological dispersal (Lieberman, 2005.; [1] Albert and Crampton, 2010. [2]). Geodispersal differs from vicariance, which reduces gene flow through the creation of geographic barriers. [3]
The southern route dispersal is primarily linked to the Initial Upper Paleolithic expansion of modern humans and "ascribed to a population movement with uniform genetic features and material culture" (Ancient East Eurasians), which was the major source for the peopling of the Asia–Pacific region.
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
The largely submarine Kuwae Caldera cuts the flank of the Late Pleistocene or Holocene Tavani Ruru volcano, the submarine volcano Karua lies near the northern rim of Kuwae Caldera. [ 2 ] Bismarck volcanic arc, the Rabaul Caldera includes the sub-vent of Tavurvur and the sub-vent of Vulcan .
Insular dwarfism, a form of phyletic dwarfism, [1] is the process and condition of large animals evolving or having a reduced body size [a] when their population's range is limited to a small environment, primarily islands.
They assimilated earlier Pleistocene to early Holocene human overland migrations through Sundaland like the Papuans and the Negritos in Island Southeast Asia. [ 146 ] [ 147 ] The Austronesian expansion was the last and the most far-reaching Neolithic human migration event.

The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
