Researchers from the UK showed that at the time and path of migrations of an ancient person from Africa, the climate had existed significant influence. The reason that the person did not settle the world immediately, are called the harsh conditions of the Middle East and competition from Neanderthal. The article of researchers was published in the journal Nature Communications.
Scientists from the University of Cambridge conducted a paleoclimatic reconstruction of the last 300 thousand years. Taking into account the minimum required for the survival of hunting collectors, the amount of precipitation, experts called the most convenient periods of time so that the ancient Homo Sapiens can be born from Africa.
Pendant Asia, a person could have two ways – through the Sinai shells and in the Bab El Mandanting Strait, when he was quite narrow due to lowering the sea level. In the first case, periodic capabilities were provided between 246 and 200 thousand years ago, 130-96 thousand years ago and about 78 thousand years ago. Cross the strait of people – probably not even possessing the skills of navigators – they could in between 242 to 275 thousand years ago, and from 182 to 145 thousand years ago. At the same time, about 65 thousand years ago both paths were “open” at the same time.
Estimates of researchers coincide with archaeological and genetic data, testifying from the fact that over the past 300 thousand years Homo Sapiens has repeatedly tried from Africa before the last, most popular and successful wave of migration that occurred about 65 thousand years ago.
Scientists explain the failure of early relocation by the harsh environmental conditions of the Middle East – in particular, the Arabian Peninsula – as well as competition with Neanderthals and, possibly, Denisovsky.
