Izilwane ziyizidalwa okuthi nje ukuba khona kwazo kusenze sizizwe singcono futhi sijabule ngokwengeziwe, ngoba zinamandla akhethekile kakhulu futhi, cishe ngaso sonke isikhathi, zithambile futhi zibukeka zinomusa.
Ngaso sonke isikhathi basenza simomotheka futhi sihleke, kepha ngangihlale ngizibuza ukuthi kwenzeka okuphambene yini, okungukuthi, ingabe izilwane ziyahleka? Ngabe unekhono lokususa ukumamatheka lapho bejabule?
Kungakho siphenye kabanzi ngalesi sihloko futhi ngiyakutshela ukuthi iziphetho zithakazelisa kakhulu. Uma ufuna ukwazi ukuthi abangane bethu basendle bangahleka yini, qhubeka ufunda le ndatshana yezazi zezilwane futhi uzoba nempendulo.
Impilo ingaba mnandi ...
... hhayi kubantu kuphela, izilwane nazo zingaba namahlaya. Kunezifundo ezithi izilwane eziningi ezifana ne- izinja, izimfene, ama-gorilla, amagundane ngisho nezinyoni angahleka. Mhlawumbe abakwazi ukukwenza ngendlela esingenza ngayo, kepha kunezimpawu zokuthi benza imisindo njengokukhala, okufana nokuhleka kwethu kepha kwehluke ngasikhathi sinye, ukuveza lapho besesimweni esihle ngokomzwelo. Eqinisweni, kufakazelwe ukuthi ezinye izilwane ziyakuthanda kakhulu ukukitazwa.
Umsebenzi ochwepheshe abawenza iminyaka eminingi awusekelwe kuphela ekwazini ubuciko bokuhleka kwezilwane, kodwa futhi nasekufundeni ukubona nokuqaphela ukuhleka ngakunye ezweni lasendle. Umndeni we-primate ungahle uhleke, kepha wenza imisindo yokuhefuzela, ukubhonga, ukukhala kanye nokuhlanza. Lapho sibona imidlwane yethu iphefumula ngokushesha nangokukhulu, akuhlali kungenxa yokuthi ikhathele noma ukuphefumula kwayo kuyashesha. Umsindo omude walolu hlobo ungamamatheka kahle futhi, kufanele kuqashelwe, unezinto ezinciphisa ukungezwani kwezinye izinja.
Izinduku nazo ziyathanda ukuhleka. Ochwepheshe kanye nochwepheshe benze izivivinyo lapho ngokukitaza ngemuva entanyeni noma ngokumema ukuthi badlale, amagundane enza imisindo ebangeni le-ultrasonic ososayensi abalitholile ukuthi lilingana nokuhleka komuntu.
Yini enye ososayensi abayishoyo?
Ngokuya ngocwaningo olushicilelwe ephephabhukwini lesayensi laseMelika elaziwa kakhulu, amasekethe ezinzwa akhiqiza ukuhleka abelokhu ekhona, abekwe ezifundeni ezindala zobuchopho, ngakho-ke izilwane zingakhombisa injabulo ngokuphelele ngomsindo wokuhleka, kepha hhayi ukuthi zisho ukuhleka ngendlela efanayo naleyo umuntu enza ngayo.
Ekuphetheni, umuntu akusiyena kuphela isilwane esikwazi ukuhleka nokuzwa injabulo. Sekuvele kuwulwazi lomphakathi ukuthi zonke izilwane ezincelisayo nezinyoni, zizwa imizwa emihle, futhi noma zingazibonisi ngokumamatheka ngoba ezingeni lomzimba wamathambo azikwazi futhi lokhu kungamandla omuntu, izilwane ziyakwenza ngezinye izindlela Humusha entweni efanayo.
Ngamanye amagama, izilwane zinendlela yazo uqobo yokusazisa ukuthi ziyajabula, njengalapho amahlengethwa egxuma ephuma emanzini noma amakati purr. Lezi yizo zonke izinhlobo zokukhuluma ngokomzwelo okufana nokumamatheka kwethu. Izilwane ziyasimangaza nsuku zonke, ziyizidalwa eziyinkimbinkimbi ngokwengeziwe ngokomzwelo kunokuba besicabanga kuze kube manje.
