Iikati zizilwanyana ezinamehlo akhethekileyo kwaye akhethekileyo. Nangona emini babona yonke into imfiliba, ngokungathi umntu ulahlekelwe ziiglasi zakhe, ngorhatya bayazazi apho bakhoyo kwaye bahamba njani ngaphandle kokukhubeka. Kodwa kutheni kunjalo?
Ewe, sinempendulo kwithuku lakhe lokuzingela. Ixhoba elinokuthi lizingele endle lisengozini ngakumbi xa ilanga litshona, kunjalo umbono weekati ebusuku kakhulu, wahluke kakhulu kulowo wabantu.
Kwiimeko eziphantsi zokukhanya iliso lomntu lifuna imizuzwana embalwa ukulungelelanisa kwaye libone "into", kodwa xa kubumnyama buphela asikwazi kubona nantoni na ngaphandle koncedo lwemibono yombono ebusuku okanye ikhamera ye-infrared. Ngokungafaniyo nekati, sizizilwanyana eziguqukayo, ke umbono wethu wobusuku awutshintshanga kangako oko saqala ukuvela kwethu
Ukuba sijonga ikati, siya kukhawuleza siqonde ukuba amehlo ayo ahlukile kwawethu. Abafundi be-Feline ba-elliptical kwimilo kwaye bajolise ngokuthe nkqo, okwenza amehlo abo avuleke ngokubanzi. Ngokwenza njalo, bamba ukukhanya okukhulu. Kodwa ayisiyiyo yonke le nto.
Amehlo abo aqulathe inwebu ebizwa ngokuba yiTapetum lucidum.. Sisipha esifunyenwe ngasemva kwibhola yamehlo kwaye linoxanduva lokubonisa ukukhanya kwemitha ukuze bakwazi ukufikelela kwi-retina. Le retina, yenziwa ziintonga ezininzi (zifunxa ukukhanya) kuneekhowuni (zifunxa imibala), ziyilelwe ukubona kwiimeko ezimnyama. Oku kuchaza ukuba kutheni le felines abahluli kakuhle eminye imibala ngaphandle kweethowuni eziluhlaza okanye ezibomvu.
Ndiyabulela kuzo zonke ezi mpawu, iikati zeekati ziyakwazi ukubona ukuya kumaxesha angama-8 ngcono kunabantu xa kuqala ukuba mnyama. Inomdla, awucingi?
