When 1 million years ago humans disappeared from Europe

More than n million years ago, Europe was hit by a brief glacial phase that led to the extinction of humans on the continent, where they then returned to stay.

Human beings arrived in Europe for the first time 1.4 million years ago from southwest Asia and since then have lived on the continent, adapting to every possible condition and surviving climate changes, even extreme ones. At least this was, until recently, the dominant theory on the spread of humans in Europe.

EXTINCT OR IN NUTS I. But now a study by UCL – London's Global University published in Science questions this interpretation by demonstrating that just 300,000 years after they had stabilized on the continent, our ancestors underwent a brief but intense period glacier that killed them or forced them to leave Europe in search of more favorable conditions.

The fact that during the millennia of human colonization Europe experienced periods of warmth and periods of intense cold has long been known: Until now it was thought that these 'micro-glaciers' did not cause problems for our ancestors, who learned to endure them until the decisive date of who learned to endure them until the decisive date 900,000 years ago, when the human footprint in Europe became dense again.

ICE IN LISBON. By analyzing marine microorganisms and pollen grains contained in a sediment sample taken from the seabed off the coast of Portugal, the UCL team found that at least one of these events had catastrophic consequences for people who were in Europe at the time. The event, which occurred 1.1 million years ago and lasted about 200,000 years, led to a collapse of temperatures: the sea off the coast of Lisbon, for example, fell below 6 °C and much of the surrounding land was reduced to deserts, almost devoid of vegetation .

This sudden change in temperatures, but also in the composition of the landscape, hit the human hunter-gatherer groups living in Europe at that time and who may not have yet known how to light fires or build durable shelters. A simulation built from these data confirmed that 1.1 million years ago the climate in the Mediterranean area became too cold and harsh for the survival of our ancestors: this would explain, among other things, the gap of about 200,000 years in the finds of stone tools. According to the study, humans returned to Europe only 900,000 years ago, when the climate became more tolerable; and since then they never left and began to colonize the continent in earnest.
