New man now for good live on every continent except Antarctica , but it was n’t always this fashion . After our metal money , Homo sapiens , emerge in Africa at least300,000 old age ago , some eventually ventured out , trekking and voyaging across the world .
So when did the first innovative human race reach out each of the seven Continent ?
Most scientists think that humans reached Australia at least 50,000 years ago. Here, an Indigenous man holds traditional weapons during a ceremonial dance at a festival in Cape York, Australia.
Out of Africa
The recognized idea about human development today are the " Out of Africa " theories , which propose thatH. sapiensevolved in Africa and distribute to the other continents , sometimes displacing or pair with other appendage of theHomogenus — do it as hominins — as they did so .
Some scientists once considered the " multiregional " speculation ( also known as the " candelabra " hypothesis ) which proposed thatH. sapiensalso evolve in other place , admit in Europe and Asia . But the multiregional hypothesis is now rejected , said paleoanthropologistMichael Petraglia , director of the Australian Research Centre for Human Evolution at Griffith University in Brisbane .
" There is no support for the multiregional or candelabrum model of human organic evolution , " he recite Live Science . " All grounds sharpen to the origin and movement ofHomo sapiensout of Africa . "

grant to late studies , H. sapiensevolved from early hominins in Africa about 300,000 year ago , and our species first dispersed from there about200,000 year ago , or roughly 100,000 years after it develop , Petraglia said .

Into Asia
Our species first spread from Africa into the eastern Mediterranean region , probably through the Sinai part between Egypt , Jordan and Israel . Although the Sinai is a desert now , scientist think it was much greener when anatomically modern humans first traveled there .
Another hypothesis suggested former forward-looking world transmigrate from Africa via a land bridge deck at the southern end of the Red Sea , across the Bab el Mandeb ( Arabic for " Gate of Grief " ) and into the Arabian Peninsula , which is also thought to have been green hundreds of thousands of years ago . A studypublished in 2006 , however , launch that there had been no such land bridge . But the researcher noted that the Bab el Mandeb had always been only a few naut mi blanket , and so it was potential that the great unwashed had swim or coggle across .
From the eastern Mediterranean , H. sapiensquickly spread east into Asia . Petraglia told Live Science in an email that multiple waves of early human may have established themselves along the nearest coastlines of Asiaby more than 100,000 years ago , then moved into its interior neighborhood . Between54,000 years ago and 44,000 years ago , someH. sapiensbred withDenisovans , another early human metal money , and so cistron variants from Denisovans now look in the genomes of many Asians .

Into Europe
The earliest evidence ofH. sapiensin Europe is from Apidima Cave in southern Greece and date to about 210,000 years ago , Martin Richards , an evolutionary geneticist at the University of Huddersfield in the U.K. , told Live Science . But if that dating is accurate , it may be from avery former wave of migratingH. sapiensthat died off or retreated during aglaciation , he say in an email .
scientist broadly live with that our speciesarrived in Europepermanently between50,000 and 60,000 years agoand that , during this meter , they breed with and put back the existing population of their close cousins , theNeanderthals .
Into Oceania
Mitochondrial DNA dating has indicated thatH. sapiensarrived in Southeast Asia about60,000 long time ago , Richards say . From there , they propagate into the prehistoric Sunda and Sahul regions that became Southeast Asia and Australia , which were mostly dry land at that time .
archeologic evidenceindicates that modern humans were in the New Guinea region up to 50,000 years ago . scientist now think they distribute from there throughout the Pacific Islands in wave of migration that include theLapita expansionabout 3,000 years ago and thePolynesian expansionfrom about 1,500 years ago .
Into North America
The conduct theory of the origins of Indigenous North Americans was once that " Paleo - Indian " people had arrived about 13,000 years ago from Siberia by journey over a solid ground span calledBeringia , to Alaska . But archeologist have now discovered evidence of pre - Clovis settlements andeven old homo footprintsfrom New Mexico that hint thefirst North Americansarrived by that itinerary , and perhaps along the Pacific coast , at least 23,000 years ago .
Into South America
archeologic and genetic evidence indicate early modern humans diffuse from North America through Central America to South America , where fossils and archaeological artifact suggest they ’d arrived byabout 15,000 years ago ; the well - studied site of Monte Verde II in southern Chile , for good example , dates to about14,550 years ago . However , some scientistsdebatethe particular date of the first human arrival in South America .

Conventionally , the first person in Antarctica was the American sealant and explorer John Davis , whoreportedly pass on the seventh continentin 1821 . However , his claim is disputed . rather , it might have been the Norse businessman Henrik Bull or the Norse explorer Carsten Borchgrevink , both of whom claimed to have belong there in 1895 . There ’s also an idea thatearly Māori sailed to Antarcticafrom New Zealand as early as the seventh century , but this isnot acceptedby many historian and scientist .
