Ancient ground squirrel droppings reveal Arctic's rich evolutionary history
Ancient ground squirrel droppings reveal Arctic's rich evolutionary history Sadie Harley Scientific Editor Robert Egan Associate Editor Ground squirrel droppings, preserved for millennia in the Yukon's deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed genetic information about an environment that no longer exists. It is among the oldest ancient DNA ever recovered and sequenced. In a...
La Fanciulla del West review – insightful staging reveals the power of Puccini’s maverick masterpiece
Opera Holland Park's production of Puccini's *La Fanciulla del West* successfully tackles the challenging opera with an insightful staging. Martin Lloyd-Evans's production draws inspiration from Yukon mining town footage, lending a gritty realism to the California gold rush setting. The performance is praised for its authentic atmosphere and the strong characterisation of the ensemble cast.
Scientists find woolly mammoth DNA while digging through squirrel faeces
A huge treasure trove of ancient DNA from animals including extinct woolly mammoths has been discovered in frozen squirrel faeces in Canada’s remote Yukon territory, scientists said on Tuesday. The DNA found deep inside sealed-off burrows is between 3,000 and 700,000 years old, offering a rare window into how life has changed over the millennia. As well as DNA from woolly mammoths – which the US company Colossal claims it is trying to “de-extinct” – genetic material was also found from...
Genome study shows what made the extinct Ice Age cave lion unique
Genome study shows what made the extinct Ice Age cave lion unique June 4 : The cave lion was one of the biggest cats to ever live, prowling a huge swathe of territory from Western Europe across Siberia and into North America and hunting large prey - and perhaps even people - before going extinct around the end of the Ice Age. New genome research reveals what made this big cat unique and how it differed from the modern lion, its smaller cousin, though the two species did sporadically...
Frozen squirrel scat preserves ancient DNA from hundreds of species
A rich and complex ecosystem stretching back 700,000 years that included woolly mammoths, bison, horses and big cats has been unveiled thanks to DNA preserved in frozen faeces. Arctic ground squirrels (Urocitellus parryii) are rodents about 40 centimetres long, found in cold regions of both North America and Siberia. These areas were joined by a land bridge in the past, with the whole region being known as Beringia.
