Pod\u013ea \u0161t\u00fadie uverejnenej v \u010dasopise Proceedings of the National Academy of Sciences vedci extrahovali a analyzovali DNA a prote\u00edny z fos\u00edlnych vzoriek, o ktor\u00fdch sa predt\u00fdm predpokladalo, \u017ee patria tigrom. \u0160t\u00fadia sa uskuto\u010dnila s cie\u013eom presk\u00fama\u0165 mo\u017enos\u0165 v\u00fdskytu levov v Japonsku, ktor\u00e9 sa nach\u00e1dza na najv\u00fdchodnej\u0161om okraji prechodov\u00e9ho p\u00e1sma medzi levmi a tigrov. Toto p\u00e1smo sa tiahne od Bl\u00edzkeho v\u00fdchodu po rusk\u00fd \u010ealek\u00fd v\u00fdchod. V\u00fdsledky uk\u00e1zali, \u017ee vzorky patria vyhynut\u00fdm levom jaskynn\u00fdm, ktor\u00ed ob\u00fdvali severn\u00fa Eur\u00e1ziu. Tigre sa vyskytovali viac na juhu.<\/p>\n

Levy opustili Afriku asi pred jedn\u00fdm mili\u00f3nom rokov a roz\u0161\u00edrili sa po euro\u00e1zijskom kontinente. Na japonsk\u00e9 s\u00faostrovie sa dostali pred asi 73.000 a\u017e 38.000 rokmi, ke\u010f po\u010das \u013eadov\u00fdch d\u00f4b klesla hladina mora a severn\u00e1 \u010das\u0165 Japonska bola spojen\u00e1 s kontinentom. Levy sa pravdepodobne roz\u0161\u00edrili do z\u00e1padn\u00e9ho Japonska. \u013dudia dorazili na s\u00faostrovie pred 40 000 a\u017e 35 000 rokmi. Levy jaskynn\u00e9 v\u0161ak pravdepodobne vyhynuli zhruba pred 10.000 rokmi.<\/p>\n
