<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">An archaeological excavation carried out in the trenches at Dhaba in the upper Son river valley in central India has found evidence of human occupation in this area almost 80,000 years ago.</span></span></p>
<p style="margin-right:0in"> </p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Background</strong></span></span></p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> The international team of researchers found evidence of the continuous presence of humans in this region between 80,000 years ago and 65,000 years ago.</span></span></p>
<p style="margin-right:0in"> </p>
<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Details</strong></span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The lithic industry (stone tools) from Dhaba strongly resembles stone tool assemblages from the African Middle Stone Age (MSA) and Arabia, and the earliest artefacts from Australia, suggesting that it is likely the product of <em>Homo sapiens</em> as they dispersed eastward out of Africa.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">This finding is important in the face of competing theories on the first presence of human populations in different regions of the world and on human dispersal from Africa.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">About 74,000 years ago, the Toba volcanic super-eruption, centred around Sumatra, is believed to have caused an almost decade-long spell of cold weather across many parts of the Earth. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">There is an argument that this induced winter not only led to the cooling of the Earth’s surface for almost a thousand years since the eruption, but also destroyed huge populations of hominins.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The hypothesis is that the ‘volcanic winter’ caused a bottleneck in the gene pool of humans, because only a few survived who were in Africa at the time. Later, this population is believed to have emerged from Africa and colonised different parts of the world. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">However, the present study rules out this hypothesis as it implies that a population of early humans inhabited northern India even before the date of the eruption (74,000 years ago) and continued through the period of the devastation and until much later.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The excavation unearthed a large tool industry spanning the period of the Toba super-eruption. The large Megalithic tools were dated between approximately 80,000 years and 65,000 years and the small tools were dated at approximately 50,000 years suggesting a continuous inhabiting of this region by humans undisturbed by the super-eruption.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The fact that we find these before and after the Toba eruption with no apparent change in technology indicates that major eruptions like Toba appear not to have had a catastrophic effect on small hunter-gatherer bands living in India at the time.</span></span></p>

<p style="margin-right:0in"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"> The international team of researchers found evidence of the continuous presence of humans in this region between 80,000 years ago and 65,000 years ago.</span></span></p>

<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The lithic industry (stone tools) from Dhaba strongly resembles stone tool assemblages from the African Middle Stone Age (MSA) and Arabia, and the earliest artefacts from Australia, suggesting that it is likely the product of <em>Homo sapiens</em> as they dispersed eastward out of Africa.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">This finding is important in the face of competing theories on the first presence of human populations in different regions of the world and on human dispersal from Africa.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">About 74,000 years ago, the Toba volcanic super-eruption, centred around Sumatra, is believed to have caused an almost decade-long spell of cold weather across many parts of the Earth. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">There is an argument that this induced winter not only led to the cooling of the Earth’s surface for almost a thousand years since the eruption, but also destroyed huge populations of hominins.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The hypothesis is that the ‘volcanic winter’ caused a bottleneck in the gene pool of humans, because only a few survived who were in Africa at the time. Later, this population is believed to have emerged from Africa and colonised different parts of the world. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">However, the present study rules out this hypothesis as it implies that a population of early humans inhabited northern India even before the date of the eruption (74,000 years ago) and continued through the period of the devastation and until much later.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The excavation unearthed a large tool industry spanning the period of the Toba super-eruption. The large Megalithic tools were dated between approximately 80,000 years and 65,000 years and the small tools were dated at approximately 50,000 years suggesting a continuous inhabiting of this region by humans undisturbed by the super-eruption.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The fact that we find these before and after the Toba eruption with no apparent change in technology indicates that major eruptions like Toba appear not to have had a catastrophic effect on small hunter-gatherer bands living in India at the time.</span></span></p>
