Cyprus's copper deposits created one of the most important trade hubs in the Bronze Age      (via sciencedaily.com) 

The coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. Recent excavations confirm the importance of the Bronze Age city in the first period of international trade in the Mediterranean.

Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America      (via sciencedaily.com) 

Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.

Lasers and chemistry reveal how ancient pottery was made -- and how an empire functioned      (via sciencedaily.com) 

Peru's first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE. The pottery they left behind gives archaeologists clues as to how the empire functioned. In a new study researchers showed that rather than using 'official' Wari pottery imported from the capital, potters across the empire were creating their own ceramics, decorated to emulate the traditional Wari style. To figure it out, the scientists analyzed the pottery's chemical make-up, with help from laser beams.

Surprising similarities in stone tools of early humans and monkeys      (via sciencedaily.com) 

Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.

The colors on these ancient pots hint at the power of an empire      (via sciencedaily.com) 

Comparing the colors on pieces of ancient Peruvian pottery revealed that potters across the Wari empire all used the same rich black pigment: a sign of the empire's influence.

The world's first horse riders      (via sciencedaily.com) 

Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today's countries of Romania and Bulgaria up to Hungary and Serbia.

Genomic study of indigenous Africans paints complex picture of human origins and local adaptation      (via sciencedaily.com) 

An international team of researchers analyzed the genomes of 180 indigenous Africans from a dozen ethnically, culturally, linguistically, and geographically diverse populations. The results shed light on the origin of modern humans, historical migrations, linguistic evolution, and local adaptation, and lay the groundwork for more people to benefit from precision medicine.

Ice Age survivors      (via sciencedaily.com) 

Large-scale genomic analysis documents the migrations of Ice Age hunter-gatherers over a period of 30,000 years -- they took shelter in Western Europe but died out on the Italian peninsula.

Oldest human genome from southern Spain      (via sciencedaily.com) 

A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.

Evolution of dinosaur body size through different developmental mechanisms      (via sciencedaily.com) 

The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found -- to their surprise -- that smaller and larger theropod dinosaurs like these didn't necessarily get that way merely by growing slower or faster.

Gene variations for immune and metabolic conditions have persisted in humans for more than 700,000 years      (via sciencedaily.com) 

A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications for understanding human diversity, the origin of diseases, and biological trade-offs that may have shaped our evolution,' says evolutionary biologists.

2.9-million-year-old butchery site reopens case of who made first stone tools      (via sciencedaily.com) 

Along the shores of Africa's Lake Victoria in Kenya roughly 2.9 million years ago, early human ancestors used some of the oldest stone tools ever found to butcher hippos and pound plant material, according to new research. The study presents what are likely to be the oldest examples of a hugely important stone-age innovation known to scientists as the Oldowan toolkit, as well as the oldest evidence of hominins consuming very large animals. Excavations at the site, named Nyayanga and located on the Homa Peninsula in western Kenya, also produced a pair of massive molars belonging to the human species' close evolutionary relative Paranthropus. The teeth are the oldest fossilized Paranthropus remains yet found, and their presence at a site loaded with stone tools raises intriguing questions about which human ancestor made those tools.

Remapping the superhighways travelled by the first Australians reveals a 10,000-year journey through the continent      (via sciencedaily.com) 

New research has revealed that the process of 'peopling' the entire continent of Sahul -- the combined mega continent that joined Australia with New Guinea when sea levels were much lower than today -- took 10,000 years. Sophisticated models show the scale of the challenges faced by the ancestors of Indigenous people making their mass migration across the supercontinent more than 60,000 years ago. This pattern led to a rapid expansion both southward toward the Great Australian Bight, and northward from the Kimberley region to settle all parts of New Guinea and, later, the southwest and southeast of Australia.
