At these iron industry sites, we discovered slags, ore fragments, tuyere, charcoal, and smelting furnaces. These discoveries provide new insights to address the debates among experts about the emergence and development of iron metal technology in Kalimantan/Borneo Island. Radiocarbon dating conducted at the Cililin 1 Cave site in the Meratus Mountains indicates that the earliest iron ore smelting occurred during the early Christian era (2000–1700 BP). Our excavations also confirm that this ferrous metal technology spread and was practiced towards the east coast and watersheds by the end of the 19th century. The excavated smelting furnaces suggest that direct smelting (bloomery) techniques were used to produce raw iron, based on the furnace shape, charcoal dates, and type of iron slag found. The shape and size of the smelting furnaces in Kalimantan remain consistent from the oldest to the most recent sites. This similarity suggests that there was little technological advancement in iron-making in Kalimantan/Borneo Island between the early AD period and the end of the 19th century. This finding supports the theory that iron technology possibly emerged and developed in Kalimantan several centuries BC.</p></div>","PeriodicalId":46860,"journal":{"name":"Anthropologie","volume":"127 3","pages":"Article 103163"},"PeriodicalIF":0.5,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47523805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to address the function of Song Toyapakeh during the late Pleistocene period, based on the animal bones found within. To accomplish this, data were collected using scuba method to record the morphology of the cave and to take samples of the animal bones that were likely used by human in the past. Macroscopic and microscopic observations were then conducted on the cut marks and burn marks present on the bones to identify evidence of human use. In addition, paleogeographical and paleoclimatological data were examined to understand the landscape transformation of the cave. The analysis of the bones revealed traces of trimming and burn marks, indicating that the bones were used as tools and as food source by humans. Changes in the landscape caused by fluctuations in the sea level due to climate change during the Pleistocene period are believed to be responsible for the transformation of the cave from an area located above sea level to one that is now submerged.

Numerous experts argue that language spread cannot always serve as evidence of human migration, as language and artifacts can diffuse without necessitating migration.

In this area, known as Indonesian Papua, the influence of Austronesian culture has been significant for thousands of years. This paper aims to investigate whether there are any parallels between the presence of Austronesian material culture and the distribution of Austronesian languages in Papua, Indonesia. The method employed involves overlaying the locations of archaeological sites containing Austronesian material culture with the distribution of Austronesian languages in the region. The results indicate that while there is some overlap between language distribution and Austronesian cultural remains in the Papua region, particularly in parts of coastal areas and surrounding island, there are also coastal areas with high Austronesian archaeological potential that lack Austronesian language presence. This is especially true in the central highlands which are predominantly Australo-Papuan areas, where Austronesian cultural influence exists but is not accompanied by the language. This demonstrates that the presence of Austronesian cultural influences in the Papua region does not always have to be associated with Austronesian migration or the language, it is possible that the culture was adopted as a result of contacts that took place.</p></div>","PeriodicalId":46860,"journal":{"name":"Anthropologie","volume":"127 3","pages":"Article 103153"},"PeriodicalIF":0.5,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49102189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The widespread distribution in the global Old World indicates their long migration route since they left Africa around 1.8 million years ago, spreading to Europe, East, and Southeast Asia, until finally reaching Java Island as the easternmost end of their migration route. Sea level regression during the Ice Age, which formed a land bridge across the Sunda Shelf, allowed migration during the Pleistocene from mainland Southeast Asia to islands Southeast Asia. Interpreted to have reached Java in the early Lower Pleistocene, their oldest fossils were found at Bumiayu, Sangiran, and Mojokerto.
