I-platypus yakwenza oko.Iipossum zenza oku.Kwanonomatse abathathu abakuMntla Merika bakwenza oku.Iidemon, iiechinopod neewombat zaseTasmania zinokwenza okufanayo, nangona ubungqina bungathembekanga kangako.
Ngaphezu koko, iindaba zamva nje zezokuba iimpuku ezimbini ezilingana nemivundla ezibizwa ngokuba “zizinambuzane zasentwasahlobo” zenza oku.Ngamanye amazwi, zikhanya phantsi kokukhanya okumnyama, kwaye i-quirks edidekileyo yezilwanyana ezincelisayo ezithile zibhidanisa izazi zebhayoloji kwaye zenza abathandi bezilwanyana emhlabeni wonke bonwabe.
Intlakohlaza etsiba-tsiba kwiisavannah zaseMazantsi nasempuma Afrika azikho kwikhadi lebhingo elikhanyayo.
Njengezinye izilwanyana ezanyisayo ezibengezelayo, zihamba ebusuku.Kodwa ngokungafaniyo nezinye izidalwa, zizilwanyana ezanyisayo zehlabathi elidala, iqela lendaleko elingazange livele ngaphambili.Ubuhle babo buyingqayizivele ye-pink orange, umbhali obiza ngokuthi "ecacileyo kwaye ecacileyo", eyenza iipateni eziguquguqukayo ngokumangalisayo, ngokuqhelekileyo zigxininise entloko, emilenzeni, ngasemva kunye nomsila.
I-Fluorescence yipropathi ephathekayo, kungekhona ipropathi yebhayoloji.Ezinye ii-pigments zinokufunxa ukukhanya kwe-ultraviolet kwaye ziphinde zikhuphe kwimibala eqaqambileyo, ebonakalayo.Ezi pigments zifunyenwe kwizilwanyana ezihlala emanzini nasemanzini nakwezinye iintaka, kwaye zongezwe kwizinto ezifana nezikipa ezimhlophe kunye nempahla yepati.
Noko ke, izilwanyana ezanyisayo azibonakali ngathi zifuna ukuba nazo ezi pigments.Kule minyaka imbalwa idlulileyo, iqela labaphandi bebelandela ngaphandle, uninzi lwabo lunxulumene neKholeji yaseNorthland e-Ashland, eWisconsin, ekubeni ilungu lesazi ngebhayoloji uJonathan Martin lalisekhaya.Ekubeni unomatse osemva kwendlu wadubula isibane se-ultraviolet, ebesoloko efuna izinto ezikhethekileyo.Isicima sayo sijika sibepinki.
Emva koko, abaphandi baya kwiMyuziyam yaseChicago enomdla kunye nezibane ezimnyama.Xa iqela lazama idrowa eneentakumba ezigcinwe kakuhle, lahleka.
“Sonke sothukile kwaye sonwabile,” utshilo u-Erik Olson, unjingalwazi wemithombo yendalo eyunivesithi kunye nombhali weli phepha litsha.“Sineengxaki ezininzi.”
Kwiminyaka elandelayo, abaphandi baphonononga iisampuli ze-springbok ezili-14 ezivela kumazwe amane, ezinye zazo ibingamadoda kwaye ezinye ingamadoda.U-Olsen uthe zonke iiseli zibonisa i-fluorescence-ezininzi zifana ne-plaque, ekhethekileyo phakathi kwezilwanyana ezanyisayo abazifundileyo.
Baye bafikelela nakwindawo yogcino-zilwanyana ukuqinisekisa ukuba izilwanyana eziphilayo zinalo olu phawu.Iifoto ze-Ultraviolet ezithathwe kwi-Henry Dolly Zoo kunye ne-Aquarium e-Omaha yeza ukuqwalaselwa ngakumbi kunye neefoto ezininzi ezinomdla apho iimpuku zikhangeleka ngathi ziqala ukukrola ngaphambi kokuba zifake ipeyinti yazo.
Iingcali zamachiza uMichaela Carlson kunye noSharon Anthony waseNorthland College bathi uhlalutyo lwekhemikhali yoboya bemivundla yasentwasahlobo lufumanise ukuba i-fluorescence ikakhulu iphuma kwiqela leebala ezibizwa ngokuba ziiporphyrins, eziye zabangela oku kwii-invertebrates zaselwandle kunye neentaka.isiphumo..
Nangona kunjalo, owona mbuzo mkhulu ngulo-kutheni onke la maphepha kunye nemigqaliselo enxulumeneyo idanyaza njengezibane ze-neon.
Izinto ezifunyaniswe entwasahlobo ngokukodwa zibonelela ngeendlela ezithile zokuhlola.Ifluorescence inokunceda izilwanyana ziphephe izilwanyana ezizidlayo ezizivayo kukukhanya kweultraviolet ngokufunxa amaza amaza ebenokuthi ngenye indlela abonakale ngokuqaqambileyo aze akhuphe ukukhanya okungabonakaliyo.U-Olsen uthe kule meko, iipateni ezinamabala afana neentakumba zinokuba yenye i-asethi.
”Ingaba ezi ntlobo zifumaneka kwinxalenye yomthi we-mammalian phylogenetic?Ngokuqinisekileyo akunjalo.”watsho uTim Caro, unjingalwazi wendalo ephilayo kwiYunivesithi yaseBristol eNgilani owayengabandakanyekanga kolu phando.Ngaba bonke banendlela yokuphila?Wathi, “Hayi."Wonke umntu utya izinto ezahlukeneyo."Ngaba bayawusebenzisa lo mbala mhle ukuze batsale amaqabane abo, ukuze sibone iimpawu zesinye isini, ngoxa esinye singenalo ifluoresce?Hayi, nayo ayizukwenzeka.“
UCarlo uthe, “Akukho pateni,” nto leyo ethetha ukuba “mhlawumbi asiwazi umsebenzi walo mbala, okanye akukho msebenzi kwaphela.”
Uthe: “Umsebenzi onzima ngoku kukubhala eli nqaku ngokubanzi kulo lonke ummandla wezilwanyana ezanyisayo,” utshilo.Landela esi sithuba.
