Kwakutheni ukuze ubukhulu bobuchopho bunciphe ukusuka kwixesha elidlulileyo?

Indaleko yobuchopho bomntu kudala ithathwa njengeyona nto ichazayo yokwanda kobukrelekrele boluntu kunye nolawulo olulandelayo lweplanethi, kunye nezigidi ezibini zokugqibela zeminyaka yokuzivelela komntu ephawulwa ngokunyuka okuphindwe kane kubungakanani bobuchopho.

Kodwa ubungqina obuninzi kutshanje bubonisa ukuba ubuchopho bomntu buguquke ngendlela engalindelekanga, buyancipha ubukhulu ngaxa lithile emva kokuphela kwexesha lokugqibela lomkhenkce, izazinzulu zatyhila.

Ngokuphathelele oku, uJeremy De Silva, unjingalwazi we-paleoanthropology kwiKholeji yaseDartmouth, wachaza ukuba inkoliso yabantu ikholelwa ukuba ubuchopho bukhula ngendlela elungeleleneyo njengoko bukhula, buze buzinzise, ​​bume kamva.” Wabonisa ukuba oku akuyonyaniso, njengabantu. baphulukene nezicubu zobuchopho ezilingana nobukhulu belamuni enye.

Ukufumanisa, iqela labaphandi elikhokelwa ngu-de Silva basebenzise umxube wefosili kunye nedatha yesampulu yanamhlanje ukufumanisa ukuba ukulahleka kwezinto ezingwevu kwenzeka phakathi kwe-3000 kunye ne-5000 kwiminyaka eyadlulayo, ngokutsho kophando olupapashwe ngoJuni kwiphephancwadi iFrontiers in Ecology kunye Indaleko.

Umgangatho woluntu udlale indima

Uninzi lwee-anthropologists ekuqaleni lwalucinga ukuba utshintsho luhambelana nokuvela kweendlela zolimo malunga neminyaka eyi-10000 eyadlulayo, kunye nokutshintsha kwehlabathi kude nokuzingela kunye nokuqokelela.

Ngelixa imihla yakutshanje yeqela likaDeSilva ikhomba kwixesha elikhulayo lempucuko yamandulo eMntla Afrika, kuMbindi Mpuma, naseMzantsi Melika, uluntu oluntsonkothileyo olukholelwa ukuba ludlale indima ekucuthekeni okwenzeka engqondweni.

Izazinzulu ziye zabika ukuba ubuchopho bomntu buhlala bulingana nobukhulu obulinganayo, malunga ne-1450 cubic centimeters, kwiminyaka eyi-150 edlulileyo, ngokutsho kweWall Street Journal.

Ngelixa lo mndilili wehle ngokukhawuleza malunga ne-10%, okanye ukuya kuthi ga kwi-150 cubic centimeters, kule minyaka ingamawaka ambalwa adlulileyo.

Ukunciphisa ubungakanani bomntu

Iqela likaDeSilva lifumanise ukuba ubungakanani bobuchopho bomntu abupheleli nje ekuncipheni, kodwa bubuye bancipha xa kuthelekiswa nobungakanani bomzimba, becebisa ukuba ubungakanani bobuchopho obuncitshisiweyo ayisiyiyo nje imveliso yemizimba yethu enciphayo.

Abaphandi bacebise ukuba imfuno yethu yokugcina ingqondo enkulu, ukugcina umkhondo wolwazi malunga nokutya, ubudlelwane boluntu, izilwanyana kunye nokusingqongileyo, mhlawumbi ziye zahla kwiminyaka embalwa edlulileyo ngenxa yokuba siye sakwazi ukugcina ulwazi ngaphandle kwamanye amalungu. yesangqa zethu zentlalo, izixeko kunye namaqela asekuhlaleni.

Lo mkhwa usenokuqiniswa kusetyenziso lwethu lwangoku lweencwadi, izixhobo zobuqu kunye ne-Intanethi njengemithombo yolwazi efanayo, ngokutsho kukaChris Stringer, isazi sembali kwiMyuziyam yeNdalo eLondon, kunye noChristoph Koch, isazi ngengqondo kwi-Allen Institute. , iziko e Seattle.

Nangona umndilili wobude bomntu ubonakala unyukile kwiinkulungwane ezimbalwa ezidlulileyo, u-Stringer uthe iintlobo zethu ziye zaba mfutshane kakhulu, zilula kwaye zincinci kwiminyaka eyi-XNUMX edlulileyo njengoko imozulu iye yafudumala, kunye nobukhulu bobuchopho buye buye bancipha ngokufanelekileyo.

“Kodwa eli isenokungabi libali liphela,” uqukumbele watsho.
