Noma yimuphi umthandi wezinja uzozazi lezo zikhathi ezikhethekile lapho isilwane saso siza kubo futhi sitshikizisa umsila ngentshiseko ekubingeleleni. Uma siye saqaphela ukukhetha indlela umsila onyakazisa ngayo, singase silungile.
Abanikazi bangase baphuthelwe ukunyakaza kanye nesiqondiso lapho umsila wenja utshikizela khona, kodwa kungaba inkomba ethakazelisayo yokwazi kangcono isilwane sethu.
Ilungelo libonisa injabulo
Ucwaningo luthole ukuthi bavame ukuya kwesokudla lapho inja izinzile futhi nomuntu abamjwayele. Abacwaningi baseChinese Academy of Sciences eBeijing babone izinja zihlangana nomuntu ezingamazi phakathi nezinsuku ezintathu. Bathola ukuthi njengoba lezi zinja zazimazi lowo muntu, zaqala ukutshikizisa imisila kaningi ziye kwesokudla zingavamisi kwesokunxele.
Umcwaningi oholayo uDkt. Yong Q Zhang uphakamisa ukuthi ukunyakaza ohlangothini lwesokudla kuxhumene nohlangothi lwesobunxele lobuchopho, lapho imizwa eyakhayo icutshungulwa khona. Lokhu kusikisela ukuthi kuwuphawu lokuthi inja izizwa ijabule noma ikhululekile, kuyilapho okuphambene kungase kusho ukuthi inja izizwa ethukile noma ethukile. Ushintsho lokunyakazisa umsila ohlangothini lwesokudla lusikisela ukuthi izinja bona umuntu ongamazi ngendlela eyakhayo uthathe isinyathelo
Lolu cwaningo, olushicilelwe kujenali iScience, lusebenzise uhlelo lokulandela ukunyakaza lwe-3D ukuze kucwaningwe ukuthi ama-beagle ayishumi anyakazisa kanjani imisila lapho enabantu phakathi neseshini yemizuzu emihlanu ngosuku izinsuku ezintathu. Sekukonke, bahlaziye izingxenye ezingu-21.000 zokunyakaza, okuhlanganisa ijubane nebanga elinyakazayo imisila yabo.
Baphinde bathola ukuthi isilwane ngasinye sine iphethini ehlukile yokuhamba, ngendlela efanayo nendlela ngamunye wethu ahamba ngayo.
Umcwaningi ophambili wathi: "izimo ezingokomzwelo ezinhle nezimbi ziye zahlotshaniswa nokusebenza kwezinhlangothi ezingakwesokunxele nezingakwesokudla ze-prefrontal cortex kubantu. Siqagela ukuthi ukunyakazisa umsila kwesokunxele kungase kuhambisane nokusebenza kobuchopho kwesokudla, kuyilapho ukunyakazisa umsila ohlangothini lwesokudla kungase kuhambisane nokusebenza kobuchopho kwesokunxele ku-prefrontal cortex.".
Ucwaningo lwezinja ezingu-18,000 XNUMX olushicilelwe ngonyaka odlule nalo lwathola ukuthi izinja zivame ukuba kwesokudla. Ucwaningo, olwenziwa yiNyuvesi yaseLincoln, lwathola ukuthi cishe amaphesenti angama-75 ezinja abonisa ukukhetha izidladla lapho zifuna ukudla. Kulaba, abangaphansi kwamaphesenti angama-60 bancamela ukusebenzisa ilungelo labo.
Ukuba nesitho esithandwayo, okwaziwa ngokuthi i-lateralization, kucatshangwa ukuthi kunenzuzo ngoba kwenza izilwane ziphumelele emisebenzini.
