How is prehistory different from history - excellent interlocutorsPrevious investigations have revealed an enormous ceremonial complex of timber circles and avenues and an artificial mound dating to the Neolithic and Bronze Age. When a bypass around Dunragit village was proposed, it was therefore important to properly investigate and record any archaeology that lay along the route. The excavations took around 19 months and revealed archaeology spanning some eight millennia, from the Mesolithic to the Iron Age period. Subsequently GUARD Archaeology has undertaken a comprehensive programme of specialist analyses of the evidence recovered during the excavations in order to bring the results to publication. The works are published as a shorter popular volume and as a more comprehensive monograph, each setting out what the GUARD Archaeologists discovered. The investigations uncovered a range of prehistoric archaeology including the earliest known house in south-west Scotland dating to the Mesolithic period, as well as Neolithic ceremonial structures, two Bronze Age cemeteries and an Iron Age village. The remains of a Mesolithic hut were discovered on the edge of a former estuary which existed here throughout prehistory. Radiocarbon dates recovered from the Mesolithic hut revealed that this structure dates to around BC with a nearby hearth dating as early as BC showing that humans had revisited this location on more than one occasion during this period after the last Ice Age, when humans first began to resettle Scotland. Over 17, Mesolithic flint microliths and knapping waste were recovered, indicating that this settlement was a focus of Mesolithic.

A new method to extract the DNA of prehistoric hominins from the soil of caves they inhabited has revealed that Neanderthals may have bounced back from the brink of extinction at least twice before their final disappearance some 40, years ago.
In a study published Thursday in Science, an international team of researchers details how they recovered fragments of Neanderthal genetic material dated to betweenand 50, years ago from cave sediments in Spain and Russia. The data indicate there were two radical replacements of the Neanderthal population throughout Eurasia, onceyears ago and againyears ago. This may be indicative of environmental pressures, possibly caused by cooling climate, that temporarily decimated local hominin groups, says Benjamin Vernot, a population geneticist from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
Both times, it seems that when conditions improved a surviving lineage of Neanderthals managed to repopulate the continent, says Vernot, who is the lead author on the study. This dramatic finding on the history of our close evolutionary cousins comes not from the discovery of new skeletons or other archaeological remains — but from mere soil.
Of these sites, Denisova Cave is perhaps the best known as it has already been the stage for a major coup in prehistoric genetics. About a decade ago, scientists sequenced the DNA of a single finger bone that had been found there and identified it as belonging to a previously unknown hominin, which they dubbed the Denisovan. Denisova Cave, which at different times housed both Neanderthals and Denisovans as well as a at least one hybrid individual has now made a new contribution to our understanding of human evolution.
The DNA extracted there and at the other two caves shows that Neanderthal populations were replaced twice by groups of the same hominin lineage but with how is prehistory different from history less genetic diversity, says Matthias Meyer, a molecular biologist from Max Planck who led the new study.
What is History
To put it in modern terms, the level of genetic difference between the older and the more recent populations was similar to what we find between humans in Africa and Europe today, Meyer says. Except of course that Africans and Europeans are contemporaneous populations, while the Neanderthal groups that replaced one another lived thousands of years apart.
It is unlikely that they were caused by one group of Neanderthals sweeping into a new region and wiping out the original population, says Vernot. What the genetic data suggest is that at some point frm large part of the Neanderthals in Eurasia died off, he tells Haaretz.
We can only speculate as to the cause of these early brushes with extinction, but the Science paper suggests they may be linked to changes in climate and environmental conditions triggered diffferent the last glacial period, which began aroundyears ago.
Most probably, modern Homo sapiens had no involvement in this postulated crisis, as back then we were still largely confined to our evolutionary cradle in Africa, even though we had already started making early forays into the Middle East and, possibly, Europe.
Add a review
Humans may have indeed had a hand in the final extinction of Neanderthals around 40, years ago, though the extent and nature of our role are still hotly debated. Special attention should also be paid to the method that was used in the study, hoq promises to be a revolutionary tool in the exploration of our evolutionary roots. Until now, archaeologists have relied on finding human remains to reconstruct the various branches of the hominin family tree.]
