Ingabe abantu kufanele baguge ngempela?

Cishe uzwile ngale ndaba (noma ujabulele i-Flick kaBrad Pitt) Icala Elimangalisayo Lenkinobho kaBenjamin, lapho umlingiswa oyinhloko, uBenjamin, eguga ngokuhlehla. Umqondo ungase ubonakale ungavamile, kodwa izimo zokuguga okuhlanekezelwe noma ukungagugi nhlobo azivamile ezilwaneni.

Uma umuntu echaza ukuguga njengokuthambekela ekufeni, kusho ukuthi I-Turritopsis Nutrica—i-jellyfish eyatholwa oLwandle LwaseMedithera—ayigugi. Kanjani? Uma umuntu omdala I-Turritopsis izacile, amangqamuzana ayo ashintshashintsha ukuze aguquke abe izinhlobo zamangqamuzana ahlukene adingwa i-jellyfish, ekugcineni avimbele ukufa. Amaseli ezinzwa angashintshwa abe amaseli emisipha, futhi ngokuphambene nalokho. Kusengenzeka ukuthi lezi jellyfish zife zingakavuthwa ngokobulili, njengoba ukungafi kwazo kungangeni kuze kube yilapho sezikhulile. I I-Turritopsis Nutrica ngokumangazayo ingenye yezibonelo ezimbalwa eziphikisana nokulindela kwethu okungokwemvelo kokuguga.

Nakuba ukungafi kuwukuthatheka komuntu, kubonakala kunososayensi oyedwa kuphela obefundisa I-Turritopsis ama-polyps kaningi elebhu yakhe: indoda yaseJapane okuthiwa u-Shin Kubota. UKubota uyakukholelwa lokho I-Turritopsis kungaba ngempela ukhiye wokungafi komuntu, futhi uyasho The New York Times, “Uma sesithole ukuthi i-jellyfish izivuselela kanjani, kufanele sizuze izinto ezinkulu kakhulu. Umbono wami wukuthi sizoguquka futhi nathi ngokwethu singafi.” Nokho, abanye ososayensi abanalo ithemba njengoKubota—yingakho kunguye yedwa ocwaninga ngokujulile i-jellyfish.

Nakuba u-Kubota enomdlandla ngakho, ukwehluka kungase kungabi ukuphela kwendlela eya ekungafini. Ukudla kwethu kungaba ukhiye wokuphila phakade—bheka nje izinyosi zezindlovukazi.

Yebo, esinye isimangaliso esingapheli inyosi yendlovukazi. Uma ingane yezinyosi inenhlanhla yokuthathwa njengendlovukazi, ubude bayo bempilo bukhula kakhulu. Isibungu senhlanhla siphathwa nge-royal jelly equkethe i-physiologically active chemical ambrosia. Ekugcineni, lokhu kudla kuvumela inyosi ukuba ikhule ibe yindlovukazi kunokuba isisebenzi.

Izinyosi eziyizisebenzi ngokuvamile zihlala amasonto ambalwa. Izinyosi zendlovukazi zingaphila amashumi eminyaka—futhi zife kuphela ngoba uma indlovukazi ingasakwazi ukubeka amaqanda, izinyosi eziyisisebenzi ezake zamlinda zamgwaza futhi zamluma waze wafa.
