Pollen, macrofossils and isotopes taken from lake sediment cores allowed the researchers to build a high-resolution picture of the climate of the area over thousands of years.
The team identified two episodes of extreme cooling which saw average temperatures drop by more than 3 degrees in the space of a decade.
The first of these events occurred very early after humans began to return to the area after the last ice age.
The evidence indicates that these conditions may have slowed down the progress and activity of a community in the nascent stages.
A great diversity of online dating services currently exists.
Some have a broad membership base of diverse users looking for many different types of relationships.
The study sheds new light on significant debate about the sensitivity of hunter-gatherer societies to environmental change.
Community The prehistoric community, who persevered through the cold snap that would last more than 100 years, left a plethora of worked wood, animal bones, antler headdresses and flint blades buried in layers of mud as evidence of their continued productivity and endurance.
“Putting this archaeological data into the context of the climate and environment is very exciting and shows that we need to keep an open mind when thinking about the effects of extreme climate on early populations.” Duncan Wilson, Historic England’s Chief Executive, said: “Star Carr is one of the best-known Mesolithic sites in Europe and is unique in Britain for the quantity and range of organic remains from this period.
The researchers examined human activity by looking at archaeological remains recovered from layers of wetland deposits at the edge of the extensive former lake basin in the Vale of Pickering.
They found evidence of houses, large wooden platforms built on the lake edge and large quantities of artefacts and bones preserved in the lake muds and these were radiocarbon dated.
“We suggest that the partially drawn object is HB9 since it would be irregular and that the second bright object is Moon since the apparent magnitude of HB9 is closer to that of the moon,” wrote the researchers.
“On the sky chart if we put the partially drawn object at the location of HB9, the image of one of the hunters coincides with the Orion, the central stag is same as the Taurus,” wrote the scientists.
