Researchers at The Australian National University (ANU) have uncovered a previously unconfirmed population boom across South East Asia that occurred 4,000 years ago, thanks to a new method for measuring prehistoric population growth.
Using the new population measurement method, which utilises human skeletal remains, they have been able to prove a significant rapid increase in growth across populations in Thailand, China and Vietnam during the Neolithic Period, and a second subsequent rise in the Iron Age.
Researcher - Clare - McFadden - PhD - Scholar
Lead researcher Clare McFadden, a Ph.D. Scholar with the ANU School of Archaeology and Anthropology, said the population trend was consistent across samples taken from 15 locations.
"We saw huge population growth associated with the agricultural transition," McFadden said.
Years - Gatherer - Type - Populations - Introduction
"Up until about 4,000 years ago you have hunter gatherer type populations, then you have the introduction and intensification of agriculture.
"Agricultural transition has been widely studied around the world and we consistently see significant population growth as a result."
Reason - Population - Changes - Tools - Populations
The reason these population changes have never been quantified before is the tools used to measure prehistoric populations were all designed for Europe and the Americas where archaeological conditions are different to Asia.
Ms McFadden said the difference comes down to how children are represented in population numbers.
Skeletal - Europe - America - Absence - Infants
"For skeletal remains in Europe and America we often see the complete absence of infants...
