Study reshapes understanding of climate change's impact on early societies
Tue, 17 Oct 2017 12:43:35 EDT
A new study linking paleoclimatology -- the reconstruction of past global climates -- with historical analysis shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt.
Paleogenomic analysis sheds light on Easter Island mysteries
Thu, 12 Oct 2017 12:30:46 EDT

The making of medieval bling
Wed, 11 Oct 2017 12:03:24 EDT
Gold has long been valued for its luxurious glitter and hue, and threads of the gleaming metal have graced clothing and tapestries for centuries. Determining how artisans accomplished these adornments in the distant past can help scientists restore, preserve and date artifacts, but solutions to these puzzles have been elusive. Now scientists have revealed that medieval artisans used a gilding technology that has endured for centuries.
Ancient humans left Africa to escape drying climate
Wed, 04 Oct 2017 15:12:31 EDT
Humans migrated out of Africa as the climate shifted from wet to dry about 60,000 years ago, according to new paleoclimate research. What the northeast Africa climate was like when people migrated from Africa into Eurasia between 70,000 and 55,000 years ago is still uncertain. The new research shows around 70,000 years ago, the Horn of Africa climate shifted from a wet phase called 'Green Sahara' to even drier than the region is now.
Modern humans emerged more than 300,000 years ago new study suggests
Thu, 28 Sep 2017 14:20:16 EDT
A genomic analysis of ancient human remains from KwaZulu-Natal revealed that southern Africa has an important role to play in writing the history of humankind.
Earliest evidence for a native African cultigen discovered in Eastern Sudan

Archaeologists examining plant impressions within broken pottery have discovered the earliest evidence for domesticated sorghum in Africa.
Ancient textiles reveal differences in Mediterranean fabrics in the 1st millennium BC
Fri, 22 Sep 2017 09:40:34 EDT
Analysis of Iron Age textiles indicates that during c. 1000-400 BC Italy shared the textile culture of Central Europe, while Greece was largely influenced by the traditions of ancient Near East.
Ancient DNA data fills in thousands of years of human prehistory in Africa
Thu, 21 Sep 2017 14:13:11 EDT
By sequencing the ancient genomes of 15 individuals from different parts of Africa, researchers reporting in the journal Cell on Sept. 21 have reconstructed the prehistory of humans on the continent, going back thousands of years. The findings shed light on which human populations lived in eastern and southern Africa between 8,000 and 1,000 years ago, the researchers say.
Reconstructing how Neanderthals grew, based on an El Sidrón child
Thu, 21 Sep 2017 14:12:15 EDT
How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? Researchers have studied the fossil remains of a Neanderthal child's skeleton in order to establish whether there are differences between the growth of Neanderthals and that of sapiens.
An extraordinary cave animal found in Eastern Turkmenistan
Thu, 21 Sep 2017 09:02:59 EDT
A remote cave in Eastern Turkmenistan was found to shelter a marvelous cave-adapted inhabitant that turned out to represent a species and genus new to science. This new troglodyte is the first of its order from Central Asia and the first strictly subterranean terrestrial creature recorded in the country.
Fly away home? Ice age may have clipped bird migration
Wed, 20 Sep 2017 14:46:53 EDT
The onset of the last ice age may have forced some bird species to abandon their northerly migrations for thousands of years, says new research led by an ornithologist. The study challenges a long-held presumption that birds merely shortened their migratory flights when glaciers advanced south to cover much of North America and northern Europe about 21,000 years ago.
How Teotihuacan's urban design was lost and found
Wed, 20 Sep 2017 11:33:46 EDT
A new article outlines how the urban design of the city of Teotihuacan differed from past and subsequent cities, only to be rediscovered and partially modeled on many centuries later by the Aztecs.
Earthquake faults may have played key role in shaping the culture of ancient Greece
Tue, 12 Sep 2017 10:35:49 EDT
The Ancient Greeks may have built sacred sites deliberately on land affected by previous earthquake activity, according to a new study.
When ancient fossil DNA isn't available, ancient glycans may help trace human evolution
Mon, 11 Sep 2017 15:09:46 EDT
Researchers have discovered a new kind of glycan (sugar chain) that survives even in a 4-million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study sets the stage for unprecedented explorations of human origins and diet.
An officer and a gentlewoman from the Viking army in Birka
Fri, 08 Sep 2017 20:55:07 EDT
War was not an activity exclusive to males in the Viking world. A new study shows that women could be found in the higher ranks at the battlefield.
The connection between an unusual pottery vessel and the development of the elites
Wed, 06 Sep 2017 14:45:48 EDT
Researchers have found a unique pottery vessel dating back some 7,200 years ago. The unique vessel was apparently used for ritual purposes, ensuring that certain people or groups could maintain their ability to store large quantities of crops.
Mobile women were key to cultural exchange in Stone Age and Bronze Age Europe
Mon, 04 Sep 2017 15:10:48 EDT
At the end of the Stone Age and in the early Bronze Age, families were established in a surprising manner in the Lechtal, south of Augsburg, Germany. The majority of women probably came from Bohemia or Central Germany, while men usually remained in the region of their birth. This so-called patrilocal pattern combined with individual female mobility persisted over a period of 800 years during the transition from the Neolithic to the Early Bronze Age.
Metallurgy likely has more than one birthplace
Fri, 01 Sep 2017 11:36:07 EDT
When and where did humans invent metal smelting? Scientists have found the answer to this long-debated question in the history of technology. Metallurgy does not have a single origin but probably arose at various locations at about the same time. The experts reached this conclusion after re-examining the 8,500-year-old copper slag and analysing the chemical composition of other copper artefacts from the Stone Age settlement of Çatalhöyük in the Near East.
Human bones in south Mexico: Stalagmite reveals their age as 13,000 years old
Thu, 31 Aug 2017 13:12:59 EDT
A prehistoric human skeleton found on the Yucatán Peninsula is at least 13,000 years old and most likely dates from a glacial period at the end of the most recent ice age, the late Pleistocene. A German-Mexican team of researchers has now dated the fossil skeleton based on a stalagmite that grew on the hip bone.
