Ukuziphatha kwamakati kungaba yindida, kangangoba ezinye izinto abazenzayo azenzi mqondo. Manje isifundo sishicilelwe ephephabhukwini Izinqubo zeRoyal Society B: Biological Sciences, iphakamisa ukuthi lezi zinsikazi ezincane, kanye nezinye izilwane ezincelisayo ezifana nezinja noma ama-hedgehogs, zingabona izinto ezingabonakali ngeso lomuntu; okungukuthi, banamandla okubona ku-ultraviolet.
Kuyamangaza, akunjalo? Mhlawumbe yingakho kwesinye isikhathi beziphatha ngokumangazayo.
Amehlo ethu akwazi ukubona kuphela lokho okwaziwa ngokuthi yi- "visual light spectrum", esukela kokubomvu kuye ku-violet. Kodwa ngaphansi kwalolu hlobo kunombala we-ultraviolet, okutholwa ezinye izilwane kuphela. Amehlo akho alungele ukudlulisa ubude be-ultraviolet, ngokwenza lokhu kukhanya kufinyelele ku-retina futhi ngaleyo ndlela kudale umfutho kagesi oya ebuchosheni, lapho imininingwane izocutshungulwa khona.
Leli khono lingasiza kakhulu kulezo zilwane ezidlayo, njengamakati. Ngenxa yayo, bayakwazi ukuthola imikhondo yomchamo, kokubili emalungwini omndeni wabo nakwezinye izinhlobo, futhi ngaleyo ndlela babe nokulawula okuningi endaweni yabo.
Ilukuluku elikhishwe kulolu cwaningo futhi elidonsa ukunakekela okunamandla yilokhu okulandelayo: ukwazi ukubona nge-ultraviolet kungenzeka ubone izinto esingaziboni, nokuthi uze udlale nabo noma ubajahe. Uma unekati elithanda ukwenza izinto ezingajwayelekile, manje singathola umbono wokuthi kungani benza izinto abazenzayo.
Ngaphandle kokungabaza, lolu cwaningo luzosiphoqa ukuba sizibone lezi zilwane ezinoboya ngenye indlela, njengoba ngibaqonda ngokwengeziwe nangaphezuluAwucabangi Futhi, mhlawumbe, kusekhona izinto eziningi okufanele sizithole.
