Kushanduka kwehuropi hwemunhu kwagara kuchionekwa sechinhu chikuru chinotsanangudza huchenjeri hwakawedzerwa hwevanhu uye hutongi hunotevera hwepasi, nemamiriyoni maviri emakore ekupedzisira ekushanduka kwevanhu achionekwa nekuwedzera kunosvika mana muhukuru hwehuropi.

Asi humwe ufakazi hunowedzera munguva pfupi yapfuura hunoratidza kuti uropi hwomunhu hwakachinja nenzira isingakarirwi, huchiderera muukuru pane imwe nguva pashure pokupera kweaizi yokupedzisira, masayendisiti akazivisa.

Nezveizvi, Jeremy De Silva, purofesa wepaleoanthropology paDartmouth College, akatsanangura kuti vanhu vakawanda vanodavira kuti kukura kwouropi kunoitika nenzira yakatevedzana sezvahunokura, hwobva hwadzikama, uye hwomira gare gare. varasa matishu europi akaenzana nesaizi yeremoni rimwe chete.

Kuti uzive, boka revatsvakurudzi rinotungamirirwa naDe Silva rakashandisa musanganiswa wefossil uye yemazuva ano sampuli data kuona kuti kurasikirwa kwegrey kwakaitika pakati pe3000 ne5000 makore apfuura, maererano nekutsvakurudza kwakabudiswa muna June mumagazini Frontiers in Ecology uye.

Hunhu hwenharaunda hwakaita basa

Mazhinji anthropologist pakutanga akafunga kuti shanduko dzakaenderana nekubuda kwemaitiro ekurima makore angangoita 10000 apfuura, uye shanduko yepasi rose kubva pakuvhima nekuunganidza.

Nepo mazuva achangoburwa eboka raDeSilva achinongedzera kunguva dzakabudirira dzebudiriro dzekare muNorth Africa, Middle East, neSouth America, nzanga dzakaoma dzavanotenda kuti dzinogona kunge dzakaita basa mukuderera kwakaitika muuropi.

Nepo avhareji iyi yakadzikira nekukurumidza nezvikamu gumi kubva muzana, kana kusvika pa10 cubic centimita, mukati mezviuru zvishoma zvemakore apfuura.

Yakaderedzwa hukuru hwevanhu

Boka raDeSilva rakaona kuti saizi yehuropi hwemunhu haina kungodzikira chete, asi zvakare yakadzikira zvichienderana nekukura kwemuviri, zvichiratidza kuti kuderedzwa kwehuropi hakusi kungobuda kwemiviri yedu iri kuderera.

Vatsvakurudzi vakakurudzira kuti chido chedu chekuchengetedza uropi hukuru, kuchengetedza ruzivo pamusoro pezvokudya, hukama hwemagariro evanhu, zvikara uye zvakatipoteredza, zvinogonawo kunge zvakaderera mumakore zviuru zvishoma zvapfuura nokuti takakwanisa kuchengetedza ruzivo kunze kune dzimwe nhengo. yemagariro edu, maguta uye mapoka evanhu.

Maitiro aya anogonawo kusimbiswa nekushandisa kwedu ikozvino mabhuku, zvishandiso zvemunhu uye Indaneti sezvinyorwa zvakafanana zvemashoko, maererano naChris Stringer, paleontologist pa Natural History Museum muLondon, uye Christoph Koch, nyanzvi yeuropi paAllen Institute. , chikoro muSeattle.

Kunyange zvazvo hupamhi hwehurefu hwevanhu hunoratidzika kunge hwakawedzera mumazana mashoma apfuura, Stringer akati mhuka dzedu dzave dzakanyanya kupfupika, dzakareruka uye dzakaonda mumakore XNUMX apfuura sezvo mamiriro ekunze aidziya, uye hukuru hwehuropi hwakaderera saizvozvo.
