ʻepekema, i no ka manawa mua manao e hoʻonohonoho i nā genomes o kahikoʻApelika

Epekema hoʻoholo ihola e hōʻoi 'ana i nā genomes o ka poʻe e noho ana i loko o Africa na tausani o ka makahiki aku nei, e like me keia, e kōkua i ka hoʻokahe i ke kukui ma luna o mākou kêia kanaka.

About ka hoʻomaka o ke ao i hōʻike hope pule ma ka makahiki halawai o ka Society no hakakino kālaimeaola a me Evolution. Ke noiʻi hookolokolo aku la ia i ka genomes o 15 kahiko kanaka, ka poe e noho ana ma kahi o 6000 makahiki aku nei i loko o ka hikina a me ka hema o Africa.

Ke aaiaoe footprint o kaʻApelika kahiko

E like me oe i ike, Africa mea he wahi kahi i hoomaka ai kanaka, e hohola a puni ka honua ma kahi o 50.000 makahiki aku nei. E like me hōʻike ma ka puke pai Science, ma keia wahi, i kekahi kanaka i ka loa genetically like. Naʻe, i ka hōʻeaʻana iʻaneʻi 2,000 makahiki aku nei, i luku aku i kakahiaka nui kānaka, iʻikeʻia e like me ka Bantu, ka poe i hana i ka mahiʻai, ka nui o ka aaiaoe ko läkou 'o ka wanaʻaoʻApelika i loko o ka māhele' āina.

Mai laila, ua hiki ke kaʻina, hoʻokahi wale'ōewe o ka kahikoʻApelika Waenaʻepekema -ʻAitiopa, o kona mau makahiki i ka 4500 makahiki. Ano, Pontus Skoglund mai Harvard University ohi i ka DNA o ka 15ʻApelika ka poe i noho mai 500 i ka 6000 makahiki aku nei.

Hihia i loko o këia DNA

Ka puke pai Nature mai nei i ka mea kahikoʻApelika Waena DNA mea paakiki e noiʻi i aie i ka mea i ka mea noho ma lalo o ka aoao o ka maikaʻiʻole aniau i loko o ke aupuni. A, he hoomahuahua i ana wela hōʻeleu i ke hoʻololi iho kaʻina DNA. Naʻe, ka noiʻi ua paa nae ka hiki ke aʻo hou e pili ana Africa ka hala, ma muli o ia ka hoʻopau o ka haumia ea a me ka loaʻa o ka moku pā pepeiao iwi, i kahiko DNA ua pono i ka malamaia.

I ka hopena o ka hana o nā kānakaʻepekema

Ka mua hopena o ke ao hōʻike i ka wanaʻao kānaka hele ma ka'āinapuniʻole nui aku ma mua o ko nā kānakaʻepekema mua manaʻo. No ka laʻana, ka mea nani e SouthʻApelika ke secede mai ka Western mau tausani makahiki aku nei.

Ka lua o ka like, mālama 'ia ma ka Carina Schlebusch mai Uppsala University ma Kuekene, ua kekahi këia i ka DNA o kahikoʻApelika. ʻepekema, ua loaʻa i nā genomes o kēiaʻApelika Waena mahiʻai i kakauiaʻi maluna DNA Bantu.

General mamo

Eia hou kekahi, mamua aku nei nō i kēia pule ua kekahi ao, a hoike i kānaka a me nā Neanderthals ke somehow launa pū 'oi ma mua o 270 tausani makahiki aku nei. Kēia mau mea, ua ulu a pena hoʻi i ka hana keaka hou nānaina o ko pehea mākou? Ueo launa pū '.

"Me kēlā hou study, e increasingly ike i ka evolutionary mōʻaukala o kēia a me ka archaic kānaka ua nui ka paʻakikī i ko mākou manaʻo 10 makahiki aku nei mākou," - wahi a ke kākoʻo '-mea kākau Fernando Rasim o ka Center no ka Study o genomes ma Nu Ioka. Mau a me ka mua, ua ulu hoopaa i kekahi manawa hou i ka manaʻo i na mea he nui o na kanaka kahiko, i like mamo.
