\u00dcks inimkonna k\u00f5ige suuremaid saavutusi l\u00e4bi aegade on edukas levik peaaegu kogu meie planeedi maismaapinnale. \u00dcks silmapaistvamaid teet\u00e4hiseid sel levikul on inimeste t\u00e4helepanuv\u00e4\u00e4rselt varajane j\u00f5udmine Austraaliasse, mituk\u00fcmmend tuhat aastat tagasi.<\/p>\n

N\u00fc\u00fcd on teadlased saanud uut geneetilist tuge teooriale, et esimesed inimesed saabusid Austraaliasse ja Uus-Guineasse juba 60 000 aastat tagasi.<\/p>\n

See oli viimase j\u00e4\u00e4aja keskpaik, merepind oli praegusest palju madalam ning Austraalia ja Uus-Guinea olid maismaasillatsi \u00fchendatud. Seda \u00fchtset maismaamassiivi on hakatud tagantj\u00e4rele nimetama Sahuliks.<\/p>\n

Millal t\u00e4pselt praeguste p\u00f5liselanike esivanemad saabusid, millist r\u00e4nnuteed m\u00f6\u00f6da ja kust nad p\u00e4rinesid, on olnud aastak\u00fcmneid arutelude k\u00fcsimus.<\/p>\n

<\/p>\n

Pedro Soares Portugalist Minho \u00dclikoolist, Martin Richards Inglismaalt Huddersfieldi \u00dclikoolist ja nende kolleegid toovad neisse k\u00fcsimusisse n\u00fc\u00fcd loodetavasti kindlamat selgust.<\/p>\n

Nad uurisid inimeste mitokondri-DNA-d, p\u00e4rilikkusainet, mis kandub edasi m\u00f6\u00f6da emaliini. Mitokondri-DNA j\u00e4rjeldati ligi kahel ja poolel tuhandel Austraalia aborigeenil, Uus-Guinea p\u00f5liselanikul ning Vaikse ookeani l\u00e4\u00e4neosa saarte ja Kagu-Aasia elanikult.<\/p>\n

Anal\u00fc\u00fcs n\u00e4itas, et Austraalia ja Uus-Guinea p\u00f5lisrahvaste esivanemad on enamjaolt p\u00e4rit Kagu-Aasiast, eriti Indoneesia p\u00f5hjaosast ja Filipiinidelt, aga ka Malaisiast ja Indo-Hiinast.<\/p>\n

Teadlased s\u00f6andavad ajakirjas Scientific Reports<\/a> v\u00e4ita, et just neist kahest suurest piirkonnast r\u00e4nnati Austraaliasse ja Uus-Guineasse, arvatavasti kahte eri teed m\u00f6\u00f6da, kuid enam-v\u00e4hem \u00fchel ja samal ajal, 60 000 aastat tagasi.<\/p>\n

Tulemus tundub kummutavat seni m\u00f5nikord v\u00e4lja k\u00e4idud m\u00f5tte, et esimesed asukad saabusid m\u00e4rksa hiljem, 50 tuhat v\u00f5i isegi 45 tuhat aastat tagasi.<\/p>\n

Teadlased uurivad n\u00fc\u00fcd lisaks mitokondri-DNA-le ka sadade inimeste tuumagenoome ja selgitavad v\u00e4lja, kas samasugune minevikupilt, nagu n\u00fc\u00fcd selgus, j\u00e4\u00e4b ka nende andmete p\u00f5hjal p\u00fcsima.<\/p>\n

Kaardil on Austraalia ja l\u00e4hi\u00fcmbrus viimasel j\u00e4\u00e4ajal. <\/p>\n
