Masayendisiti kokutanga yakasarudza aronge genomes ose Africans yekare

Masayendisiti vakasarudza streamline kuti genomes vanhu vaigara Africa zviuru zvemakore akapfuura, sezvo izvi zvichabatsira kuti kujekesa mavambo edu.

About pakutanga kudzidza zvakaziviswa svondo rapera pamusangano wepagore of Society kuti Molecular Biology uye Evolution. Vaongorori amutsvaka genomes vanhu 15 vekare vakararama anenge 6000 apfuura kumabvazuva uye kumaodzanyemba kweAfrica.

The majini chavangayeukwa the Africans yekare

Sezvaunoziva, Africa ndiyo nzvimbo vanhu vakatanga kupararira munyika anenge 50,000 apfuura. Sezvinoratidzwa inonzi Science, munharaunda ino, vanhu vari ndiyewo majini siyana. Zvisinei, pakasvika pano makore 2,000 apfuura, mangwanani vanhu, anozivikanwa somunhu dzeChirungu dzaiva, uyo vaiita zvokurima, vakaparadza zvakawanda majini kungoda mangwanani Africans mudunhu.

Kubvira ipapo, masayendisiti akakwanisa kutevedzana mumwe chete Gene ane African vekare - muItiopia, vane zera iri makore 4500. Zvino Pontasi Skoglund rokuHarvard University raunganidza DNA 15 veAfrica vaigara kubvira 500 kusvika 6000 apfuura.

Zvinetso kudzidza DNA

Inonzi Nature anoti rekare African DNA zvakaoma kudzidza nokuti kuti yakaramba ichitevedzera zvakaipa okunze munyika. Uyezve, kuwedzera kupisa Inowedzera kuti kudzikisirana muitiro DNA. Zvisinei, vaongorori vakanga vachiri kukwanisa kudzidza zvakawanda pamusoro Africa kare, nokuda kuchaitwa nokusvibiswa uye kuwanikwa duku dzomukati nzeve mapfupa, izvo kare DNA zvakanaka vakachengetedzwa.

Zvakabuda basa masayendisiti

Rokutanga migumisiro pakudzidza dzinoratidza kuti vanhu vokutanga akafamba mhiri kondinendi kupfuura masayendisiti kare akafunga. Somuenzaniso, zvinoita sokuti South Africans aigona secede kubva Western mashoma zviuru zvemakore akapfuura.

Kudzidza wechipiri, kwaitungamirirwa Carina Schlebusch kubva Uppsala University kuSweden, kudzidzawo muDNA vomuAfrica yekare. Masayendisiti akawana kuti genomes hwemazuva varimi African raiva DNA dzeChirungu dzaiva.

General zvizvarwa

Uyezve, ambotaurwa vhiki rino paiva neimwe yokudzidza, izvo zvinoratidza kuti vanhu uye Neanderthals vaigona zvimwe dyidzana anopfuura zviuru 270 apfuura. Zvakawanikwa izvi kupenda zvinoshamisa itsva maonero sei rudzi edu dyidzana.

"With nomumwe kudzidza zvitsva, tiri kuramba kuziva kuti shanduka nhoroondo ano uye zvekare vanhu kwakanga kwakaoma zvikuru isu pane akafunga makore 10 apfuura," - akati co-munyori Fernando Rasim Muzinda Wokudzidza genomes mu New York. Izvi yapfuura zvakawanikwa uye zvinoratidza kamwe zvakare pfungwa yokuti vazhinji vekare vaiva zvakafanana zvizvarwa.
