Kungani izinyoni zingenamazinyo - inguqulo yososayensi

Ososayensi eyunivesithi yaseJalimane baveze imfihlo yokuthi kungani izinyoni zingenamazinyo. Ngokusho kwengqondo eqinile yesintu, le nkinga ihlala ekuziphendukeleni kwemvelo. Zonke izibankwakazi ezindizayo ezazihlala ezintabeni zalahlekelwa amazinyo. Bazama ukuthola ukudla empukwini noma ukubamba izinambuzane phakathi kwamatshe.

Ososayensi bathi ukwenqaba kwamazinyo okuziphendukela kwemvelo kwavula izinyoni ithuba. Okungukuthi, ukunciphisa isikhathi sokufakwa lapho kudonswa inzalo. Ngokusho kochwepheshe, imvelo ithatha isikhathi esithe xaxa ukwakha amazinyo.

Futhi isikhathi sezinyoni siyinsiza ebucayi. Yize kunjalo, inqwaba yezilwane, izinyoni nezilwane ezihuquzelayo iphupha ukudla isidlo sasemanzini.

Kungani izinyoni zingenawo amazinyo

Isitatimende sososayensi baseJalimane sagxekwa. Ochwepheshe bathi ukuthola iziphetho ngokusekelwe esikhathini sokufakwayo kuwubuwula. Ngemuva kwakho konke, isikhathi sokuzalwa kwenzalo ngohlobo ngalunye lwezinyoni luyahlukahluka. Ukunyamalala kwamazinyo kungachazwa ngokuwohloka kwezimo zezulu - lapho izinyoni zidinga ukuthola ukudla ngaphansi kweqhwa noma amatshe.

Kuze kube nobunye ubufakazi, umbuzo wokuthi "kungani izinyoni zingenamazinyo 'uhlala uvulekele wonke umuntu. Kungenzeka ukuthi izinyoni azikaze zibe namazinyo, futhi ama-dinosaurs ezindizayo anamazinyo aguqukayo ngokwemvelo wokuhlafuna kahle ukudla ngemuva kokuzingela.
