Impucuko yama Mayan yenye yezona zihambele phambili mandulo, njengoko kubonisiwe bubutyebi obuninzi bezinto zakudala obusekho nanamhlanje. Nangona kunjalo, amaqondo obushushu aphezulu abangela iingxaki ezinkulu, ukuya kuthi ga Babengoyena nobangela uphambili wemfazwe eyabakho esiphelweni sobukho bayo.
Oku kuchazwe liqela labembi bezinto zakudala kunye neenkcukacha-manani ezivela kwiYunivesithi yaseSimon Fraser eCanada, abathe bapapasha uphando lwabo kwijenali 'Quaternary Science Reviews'. Ngaba nathi siza kufumana ikamva?
Abaphandi bafunde ngeziganeko ezenzeka phakathi kwe-AD 363 kunye ne-AD 888. C., Eli lixesha apho ubume bokwakhiwa kweMeya babuhlala khona ngelixa inani leemfazwe lonyuka, ukuze kufumaneke ukuba loluphi uhlobo lokutshintsha kwemozulu olunokuthi ludlale ekonyuseni iimfazwe kwixesha elizayo.
Ke, ngemodeli yeenkcukacha-manani, Baye bakwazi ukuqinisekisa ukuba imvula ayibuchaphazeli ubundlobongela, kodwa ukwanda kwamaqondo obushushu kubenze baba nobundlobongela. Umbhali osebenza naye kufundaUMark Collard ucacisile ukuba "izifundo ezininzi zichaza ukuba abantu banoburharha ngakumbi kwiindawo ezishushu." Nangona kunjalo, wongeze ukuba kwii-Mayan eyona nto ibalulekileyo yayihambelana nefuthe lamaqondo obushushu aphezulu kulimo lombona.
Umbona wawubaluleke kakhulu kubo, kangangokuba udumo lweenkokheli luxhomekeke, kungekuphela kwimpumelelo yabo kumadabi, kodwa kwanokuba bayakwazi na ukulima okuziinkozo ngokwaneleyo ukuze wonke umntu ondliwe. Xa kukho imbalela kunye namaza obushushu, izivuno zazincitshiswa kakhulu, ukuze bakhethe ukuthatha inxaxheba kwiingxabano zomkhosi.
Nangona kunzima ukwazi ukuba ubushushu behlabathi buza kuzisa iimfazwe ezininzi, yinto esingafanele ukuyikhupha. Abanye bathi Imfazwe elandelayo iya kubakho leyo yamanzi; Ayothusi into yokuba baninzi abantu abahlala apha kwaye zimbalwa kwaye zimbalwa izixhobo esinazo.
