People Deforested the Central African Tropical Rain Forest 2,600 Years ago

The forested expanses of Central Africa host the second largest block of tropical rainforest on Earth (after Amazonia), stretching over around 2 × 106 km2. They are the great green heart of Africa, and changes in vegetation cover are likely to have important but poorly understood influences on the climate of much of the continent (1). A remarkable feature is that this blanket of forest appears quite tenuous—under the arid climates of the ice ages, the forest appears to have retreated into isolated pockets surrounded by savanna grasslands. Even in the climatically stable Holocene, there appears to have been periods of substantial forest retreat. In particular, there is evidence for a period of major forest loss between 3,000 and 2,000 y ago [termed the Late Holocene rainforest crisis (LHRC) (2)]. Attributing the cause of this decline is complicated by the fact that this period coincided with major expansion of Neolithic and early Iron Age farmers southward from the Nigeria/Cameroon border regions into western Central Africa. Did the farmers take advantage of a forest retreat driven by climate drying, or were they the primary cause of the forest loss? In recent years, there has been a vigorous debate on the cause of the LHRC. Now, Garcin et al. (3) provide new data and an unexpected new insight, presenting strong evidence that there was no strong drying event, and therefore suggesting that it was direct deforestation that caused this retreat of the Central African rainforests.

Better start rethinking the anthropocene, folks.

Metal Workers of Iron Age Slave's Hill Were NOT Slaves

In 1934, American archaeologist Nelson Glueck named one of the largest known copper production sites of the Levant "Slaves' Hill." This hilltop station, located deep in Israel's Arava Valley, seemed to bear all the marks of an Iron Age slave camp – fiery furnaces, harsh desert conditions, and a massive barrier preventing escape. New evidence uncovered by Tel Aviv University archaeologists, however, overturns this entire narrative.

In the course of ongoing excavations at Timna Valley, Dr. Erez Ben-Yosef and Dr. Lidar Sapir-Hen of TAU's Department of Archaeology and Near Eastern Cultures analyzed remnants of food eaten by copper smelters 3,000 years ago. The result of this analysis, published in the journal Antiquity, indicates that the laborers operating the furnaces were in fact skilled craftsmen who enjoyed high social status and adulation. They believe their discovery may have ramifications for similar sites across the region.

"What we found represents a general trend or reality related to metal workers in antiquity," said Dr. Ben-Yosef. "They had a very unique role in society, and we can demonstrate this by looking at Timna."

Evidence the 'Sea People' of the Eastern Mediterranean Were European

Swedish archaeologists in Jordan led by Professor Peter M. Fischer from the University of Gothenburg have excavated a nearly 60-metre long well-preserved building from 1100 B.C. in the ancient settlement Tell Abu al-Kharaz. The building is from an era characterised by major migration.

New finds support the theory that groups of the so-called Sea Peoples emigrated to Tell Abu al-Kharaz. They derive from Southern or Eastern Europe and settled in the Eastern Mediterranean region all the way to the Jordan Valley.

'We have evidence that culture from present Europe is represented in Tell Abu al-Kharaz. A group of the Sea Peoples of European descent, Philistines, settled down in the city,' says Peter Fischer. 'We have, for instance, found pottery resembling corresponding items from Greece and Cyprus in terms of form and decoration, and also cylindrical loom weights for textile production that could be found in central and south-east Europe around the same time.'

Tell Abu al-Kharaz is located in the Jordan Valley close to the border to Israel and the West Bank. It most likely corresponds to the biblical city of Jabesh Gilead. The Swedish Jordan Expedition has explored the city, which was founded 3200 B.C. and lasted for almost 5 000 years. The first excavation took place in 1989 and the most recent in autumn 2013. All in all, 16 excavations have been completed.

Peter M. Fischer and his team of archaeologists and students have surveyed an urban settlement that flourished three times over the 5 000 years: around 3100-2900 B.C. (Early Bronze Age), 1600-1300 B.C. (Late Bronze Age) and 1100-700 B.C. (Iron Age). These are the local periods; in Sweden, they occurred much later.

Remarkably well-preserved stone structures have been exposed during the excavations. The finds include defensive walls, buildings and thousands of complete objects produced locally or imported from south-east Europe.

'What surprises me the most is that we have found so many objects from far away. This shows that people were very mobile already thousands of years ago,' says Fischer.
