One of the grownup moments in human history drive berth 60,000 to 70,000 years ago when a portion ofHomo sapiensleft Africa . Despite this epoch ’s Brobdingnagian significance , we know surprisingly minuscule about people ’s whereabouts from 70,000 to 45,000 years ago when they first jell foot into the wider world .
Thanks to a combination of genetic , palaeoecological , and archeologic evidence , scientists have uncovered that the Persian Plateau served as a vital hub forHomo sapiensduring the early stages of their migration out of Africa , consort to a 2024 study write in the journalNature Communications .
The region likely provided a “ home away from home ” for around 20,000 years , tolerate a important population ofHomo sapiensto build up and flourish before theydispersed across Eurasiaand beyond .

This means that the ancestors of all present - 24-hour interval non - Africans lived in the Persian Plateau for around 20,000 years after the migration out of Africa . In other words , if you have any familial inheritance from Europe , Asia , the Americas , or Oceania , some of your antecedent likely spent a substantial percentage of their clip in this field .
To get through these finding , the team reckon at genetic evidence from prehistorical and modern human populations and found that people around the Persian Plateau have close ancestral ties to the universe that first finalise outside Africa . The researchers also ran a palaeoecological model that evidence the region was much more hospitable than other possible hubs comply theOut of Africa enlargement .
The Persian Plateau is a vast elevated realm located in southwest Asia , found eastwards of the Zagros Mountains across modern - day Iran , as well as Afghanistan and Pakistan . Surrounded by the Caspian Sea , the Persian Gulf , and the Mediterranean , the domain provided the idealistic habitat to start fostering larger populations . Simultaneously , its location was perfect for attend to as a “ launch pad ” for thenumerous waves of peoplesettling across Eurasia .
“ The discovery elucidates a 20,000 - year - long portion of the history ofHomo sapiensoutside of Africa , a timeframe during which we interact withNeanderthalpopulations , and sheds light on the relationships between various Eurasian populations , providing crucial clues for sympathise the demographic history of our metal money across Europe , East Asia , and Oceania , ” first study author Leonardo Vallini , of the University of Padova in Italy , said in astatement .
“ Interaction ” with Neanderthals is one direction to put it . In 2024 , another squad of scientists established that the Zagros Mountains to the west of the Persian Plateauwas a locationwhereHomo sapiensand Neanderthals prolifically hybridize with each otheraround 47,000 years ago .
While recent archeological finds have started to suggest that the Persian Plateau was once a crucial hub for gallivantingHomo sapiensin their early forays outside of Africa , this latest enquiry indicate that many more fossil and artifact are potential to be hidden here , ripe for discovery .
“ Our multidisciplinary study provides a more coherent purview of the ancient past , offer up insight into the critical stop between the Out of Africa enlargement and the differentiation of Eurasiatic population , ” said study co - author Professor Michael Petraglia .
" The Persian plateau emerges as a primal region , underscore the need for further archeological explorations . ”
