The quest to revive extinct Aurochs to restore ancient lands

Rewilding and restoration of land often rely on the reintroduction of species. But what happens when what you want to reintroduce no longer exists? What if the animal in question is not only locally extinct, but gone for good? Yes, this might sound like the plot of Jurassic Park. But in real life this is actually happening in the case of the Aurochs ( Bos primigenius ). This wild ancestor of all modern cattle has not been seen since the last individual died in 1627 , in today’s Poland. Aurochs have been deep within the human psyche for as long as there have been humans, as attested by their prominence in cave art. However, the advent of agriculture and domestication put the magnificent animal on a path to extinction. So why bring the Aurochs back today and how? And what is the likely outcome? What is left of Aurochs, besides their depiction in cave paintings, are some fossil remains and some descriptions in the historical record. “Their strength and speed are extraordinary,” w...

Making thread in Bronze Age Britain

-

A new study published this week in the journal Archaeological and Anthropological Sciences has identified that the earliest plant fibre technology for making thread in Early Bronze Age Britain and across Europe and the Near East was splicing not spinning.
In splicing, strips of plant fibres (flax, nettle, lime tree and other species) are joined in individually, often after being stripped from the plant stalk directly and without or with only minimal retting -- the process of introducing moisture to soften the fibres.
According to lead author Dr Margarita Gleba, researcher at the McDonald Institute for Archaeological Research, University of Cambridge, "Splicing technology is fundamentally different from draft spinning. The identification of splicing in these Early Bronze Age and later textiles marks a major turning point in scholarship. The switch from splicing -- the original plant bast fibre technology -- to draft spinning took place much later than previously assumed."
Splicing has previously been identified in pre-Dynastic Egyptian and Neolithic Swiss textiles, but the new study shows that this particular type of thread making technology may have been ubiquitous across the Old World during prehistory.
"The technological innovation of draft spinning plant bast fibres -- a process in which retted and well processed fibres are drawn out from a mass of fluffed up fibres usually arranged on a distaff, and twisted continuously using a rotating spindle -- appears to coincide with urbanisation and population growth, as well as increased human mobility across the Mediterranean during the first half of the 1st millennium BC."
"Such movements required many more and larger and faster ships, all of which largely relied on wind power and therefore sails. Retting and draft spinning technology would have allowed faster processing of larger quantities of plant materials and the production of sail cloth."
Among the finds analysed for this study are charred textile fragments from Over Barrow in Cambridgeshire, dated to the Early Bronze Age (c. 1887-1696 BC). The site was excavated by the Cambridge Archaeological Unit.
Dr. Susanna Harris of the University of Glasgow, co-author of the paper and expert in British Bronze Age textiles notes: "We can now demonstrate that this technology was also present in Britain. It's exciting because we think the past is familiar, but this shows life was quite different in the Bronze Age."
"Sites like Over Barrow in Cambridgeshire contained a burial with remains of stacked textiles, which were prepared using strips of plant fibre, spliced into yarns, then woven into textiles."
"It had always been assumed that textiles were made following well-known historical practices of fibre processing and draft spinning but we can now show people were dealing with plants rather differently, possibly using nettles or flax plants, to make these beautiful woven textiles."

Cranium of a four-million-year-old hominin shows similarities to that of modern humans

A cranium of a four-million-year-old fossil, that, in 1995 was described as the oldest evidence of human evolution in South Africa, has shown similarities to that of our own, when scanned through high resolution imaging systems. The cranium of the extinct Australopithecus genus was found in the lower-lying deposits of the Jacovec Cavern in the Sterkfontein Caves, about 40km North-West of Johannesburg in South Africa. Dr Amelie Beaudet from the School of Geography, Archaeology and Environmental Studies of the University of the Witwatersrand and her colleagues from the Sterkfontein team scanned the cranium at the Evolutionary Studies Institute, based at the University of the Witwatersrand, in 2016 and applied advanced imaging techniques in "virtual paleontology" to further explore the anatomy of the cranium. Their research was funded by the Centre of Excellence in Palaeosciences, the Claude Leon Foundation and the French Institute of South Africa and was published i...

99-million-year-old beetle trapped in amber served as pollinator to evergreen cycads

Flowering plants are well known for their special relationship to the insects and other animals that serve as their pollinators. But, before the rise of angiosperms, another group of unusual evergreen gymnosperms, known as cycads, may have been the first insect-pollinated plants. Now, researchers reporting in the journal Current Biology on August 16 have uncovered the earliest definitive fossil evidence of that intimate relationship between cycads and insects. The discovery came in the form of an ancient boganiid beetle preserved in Burmese amber for an estimated 99 million years along with grains of cycad pollen. The beetle also shows special adaptations, including mandibular patches, for the transport of cycad pollen. "Boganiid beetles have been ancient pollinators for cycads since the Age of Cycads and Dinosaurs," says Chenyang Cai, now a research fellow at the University of Bristol. "Our find indicates a probable ancient origin of beetle pollination of...
