Thanks to a multidisciplinary team of researchers from several countries, we have achieved specify the dates when Neanderthals and Denisovans are considered, they lived in Denisova beer in Siberia. Two articles published in the journal Nature They provide an overview of the findings of this group of experts from the UK, Russia, Canada, Australia and Germany.
Located in the Southern Siberian Altai Mountains, Russia Denisov Cave is the only place in the world known to be occupied Neanderthals and Denisovani, extinct relatives closest to people.
First, the team you run Katerina Douka of the Max Planck Institute In the field of German human history, he analyzed three new fragments of Denisovan fossils radiocarbonate.
The team concluded that the presence of Denisovans in the cave is returning at least 195,000 years ago and that the latest hominid fossil of this kind dates back to the period between 76,000 and 52,000 years ago.
Most evidence Neanderthal presence cave belongs to the last inter-book period, about 120,000 years ago, when the weather was relatively warm. Although denisovanos survived much colder periods before they disappeared about 50,000 years ago.
About 100,000 years ago, in two groups, hominide existed in a cave and blended as a recent exploration of the bone fragment "Denisova 11", owned by Neanderthal's mother and Denisovan's father.
Douka's study, which scientists from British University of Oxford, also identified by radiocarbonate dating bones and pendants made from teeth of 49,000 to 43,000 years old animals. This estimate makes them the oldest artefacts discovered in Northern Eurasia and are thought to be Denisovans' work.
On the other hand, Zenoby Jacobs and Richard Roberts University of Wollongong, Australia they studied cave sediments with a luminescence system that evaluates the passage of time, as some minerals such as quartz were last exposed to sunlight.
With this method, they created a timeframe for fossil and artefact accumulation in the cave, ranging from 300,000 to 20,000 years. From these data, they estimate that Denisovans took a cave about 287,000 to 55,000 years ago, while Neanderthals lived between 193,000 and 97,000 years ago.
