Its teeth are not so determinant in its survival,&quot; said Vargas.&quot;It hunts large prey with its human companions. This sample reflects that difference.&quot;Humans are believed to have migrated to the Americas across the Bering Strait from Siberia to Alaska during the last great ice age.&quot;The first domesticated dogs entered the continent about 15,000 years ago, a product of Asians migrating across the Bering Strait,&quot; said Raul Valadez, a biologist and zooarcheologist from the National Autonomous University of Mexico.&quot;There have never been dogs without people,&quot; Valadez told AFP by telephone.The presence of humans during the Pleistocene has been attested in Mexico, Chile and Patagonia, but never in Central America, until now.&quot;This could be the oldest dog in the Americas,&quot; said Vargas.So far, the oldest attested dog remains were found in Alaska and are 10,150 years old.Oxford University has offered to perform DNA and carbon dating tests on the sample to discover more genetic information about the animal and its age.The fossil is currently held at Costa Rica&#x27;s national museum but the sample cannot be re-identified as a dog without validation by a specialist magazine.&quot;This dog discovery would be the first evidence of humans in Costa Rica during a period much earlier&quot; than currently thought, said Vargas.&quot;It would show us that there were societies that could keep dogs, that had food surpluses, that had dogs out of desire and that these weren&#x27;t war dogs that could cause damage.&quot;<div>RELATED VIDEO</div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=1657022" width="100%"></iframe></figure><div class="iwantbar">Watch more in <a href="//www.iwantv.com.ph/">iWantv</a> or <a href="//tfc.tv/">TFC.tv</a></div>
