A new one research has light on the origin and removal of a rhinoceros rising en weeping of & # 39; e Ice Age known as the Siberian unicorn.
An international team of researchers from Adelaide, Sydney, London, Nederland en Russia, have a long discussion on the relationship of the Siberian unicorn with lively roots, and decides that it survived much later than previously, until it overlooks time with modern people.
Published in the magazine Nature Ecology and Evolution and directed by the Natural History Museum from London, researchers say that the Siberian unicorn had extinct 36,000 years. This was probably due to the reduction in the steppe pasture that he lived, due to climate change or the influence of ' man.
Today, there are only five types of surviving rhinos, although in the past 250 species.
With a weight of up to 3.5 tonnes with a great horn, the Siberian unicorn (Elasmotherium sibiricum), to make the stones of Russia, Kazakhstan, Mongolia and North China, was without a doubt one of the most impressive.
However, genetic analyzes have been done in Australian Center for the Old DNA (ACAD) of # University of Adelaide have shown that the Siberian single-horn was the last surviving member of a unique rhinos family.
"The ancestors of the Siberian unicorn separated from ancestors of all living rhinos over 40 million years ago," says the co-author and researcher of ACAD, de Dr. Katherine Mitchell, the DNA analyzed from Siberian unicorn. It is the first time that DNA returned from E. sibiricum.
"This makes the Siberian unicorn and the African white rhinoceros more liberal than man to monkeys."
These new genetic movements send earlier studies that the Siberian single-horn had a high ratio of extinct rhinos and the lively rhinos of Sumatra.
For a long time it was assumed that the Siberian one-horn for the last time died Ice Age, perhaps even until 200,000 years.
In this study, 23 samples of Siberian single-horned bones were dated, confirming that the species survived at least 39,000 years, and possibly up to 35,000 years ago. The last days of the Siberian single one were shared with the first Modern people and neandertals.
"It is not likely that the presence of human beings is the cause of exploitation," says co-authors Professor Chris Turney, a scientist at the # 39; the University of California. University of New South Wales.
"The Siberian single-horn seems too strongly influenced by the beginning of the ice age Eurasia as a fall of 'e temperature causing an increase in earthquake soils, hard and dry green impediments and influence of populations in a great region, "he said.
Other species that served the area of Siberian one's yawn, were less dependent on & # 39; the grass, such as the rhinoceros, or more flexible in their diet, such as the saiga antelope, and the absence of the plurality of Siberian single horns, although the rhinoseros were extinct extinct 20,000 years later.
