Amakati yizilwane ezinamehlo ahlukile futhi akhetheke kakhulu. Yize emini babona konke kufiphele, sengathi othile ulahlekelwe yizibuko, kusihlwa bayazi ukuthi bakuphi nokuthi bangahamba kanjani ngaphandle kokukhubeka. Kodwa kungani kunjalo?
Impendulo sinayo kumzwelo wakhe wokuzingela. Impango ebingazingela ngokwemvelo isengozini enkulu lapho ilanga lishona, ngakho-ke umbono ebusuku wamakati uhluke kakhulu kunowabantu.
Ezimweni zokukhanya okuphansi iso lomuntu lidinga imizuzwana embalwa ukujwayela futhi libone "okuthile", kepha ebumnyameni obuphelele asikwazi ukubona lutho ngaphandle kosizo lwezibuko zokubuka ebusuku noma ikhamera ye-infrared. Ngokungafani nekati, siyizilwane ezihamba ngonya, ngakho-ke umbono wethu wasebusuku awukashintshi kakhulu selokhu saqala ukuvela.
Uma sibheka ikati, sizobona ngokushesha ukuthi amehlo alo ahlukile kwelethu. Abafundi be-Feline bayi-elliptical ngesimo futhi babheke phezulu, okwenza amehlo abo avuleke ngokwengeziwe. Ngokwenza kanjalo, thatha inani elikhulu lokukhanya. Kepha akupheleli lapho.
Amehlo abo aqukethe ulwelwesi olubizwa ngeTapetum lucidum.. Kuyisicubu esitholakala ngemuva kwezinhlamvu zamehlo futhi esibhekele ukukhombisa imisebe yokukhanya ukuze ikwazi ukufinyelela ku-retina. Le retina, eyakhiwa izinduku eziningi (zimunca ukukhanya) kunezigaxa (zimunca imibala), yakhelwe ukubona ezimweni ezimnyama. Lokhu kuchaza ukuthi kungani la ma-felines azihlukanisi kahle eminye imibala kunamathoni aluhlaza okwesibhakabhaka noma we-violet.
Ngenxa yazo zonke lezi zimfanelo, amehlo amakati abona kangcono izikhathi eziphindwe kasishiyagalombili kunabantu lapho kuqala ukuba mnyama. Kuyathakazelisa, awucabangi?
