Kungani izinja zasekhaya zinezindlebe ezilengayo, ngokungafani nezihlobo zazo zasendle?
Abacwaningi baye baphetha ngokuthi kwakuyiphutha enqubweni yezinto eziphilayo lapho izilwane ziba mnene, kubhala i-ABC News.
Izindlebe ezilengayo izinhlobo eziningi zezinja ezinazo azitholakali ezinjeni zasendle. Izinja zasekhaya nazo zinamakhala amafushane, amazinyo amancane, nobuchopho obuncane. Abacwaningi bayibiza ngokuthi “i-domestication syndrome”.
Phakathi neminyaka edlule, abacwaningi baye baba nezinkolelo-mbono eziningi, kodwa ayikho eyamukelwa kabanzi. Eminyakeni yamuva, abacwaningi baseJalimane, e-United States, e-Austria naseNingizimu Afrika baye bahlola imibungu yezilwane ezinomgogodla. Kuye kwaboniswa ukuthi ukuzalanisa okukhethiwe kungenza ama-stem cells athile angasebenzi, "alahleka" endleleni eya engxenyeni yomzimba lapho ayezoqala khona ukwakha izicubu (lapho etholakala khona ezilwaneni zasendle). Isibonelo salokhu ukuphaphaza kwezindlebe.
- Uma ukhetha ukukhetha ukuze uthole isici, uvame ukuthola okuthile obungakulindele. Ezilwaneni ezifuywayo, eziningi zazingeke ziphile endle uma zidedelwa, kodwa lapho zivalelwe, zenza kahle. Futhi noma ngabe iminonjana ye-Domestication syndrome inesici ngokwezobuchwepheshe, ayibonakali iyingozi kubo, kusho u-Adam Wilkins e-Institute of Theoretical Biology.
