Kungani izinja zinamehlo adabukile?

O, lokho kubukeka okuhle! Ngokuqinisekile wonke umnikazi uzokhumbula amacala angaphezu kwelilodwa lapho engakwazi ukumelana namehlo adabukisayo esilwane sakhe esifuywayo. Futhi wenza lokho inja ekucelile, ngisho noma wayengahlosile. Ososayensi baye bafinyelela esiphethweni sokuthi izinja ziye zafunda “ukwenza amehlo” ukuze zithonye abangane be-bipedal.

Imisipha ebhekene nalokhu kubukeka "komdlwane", okuyinto umuntu ayiqonda kahle futhi eyenza sincibilike, yakhiwe ngesikhathi sokuziphendukela kwemvelo, ngenxa yokuxhumana phakathi kwabantu nabangane bethu abakhulu. Ngaphezu kwalokho, abantu abathanda lesi sici babonise ukukhetha ezinja ezinjalo, futhi ikhono lokwenza "ukubukeka okuhle" ezinjeni lalungiswa.

Abacwaningi baqhathanisa umehluko phakathi kwezinja nezimpisi. Futhi bathola ukuthi izinja "zakha" imisipha evumela ukuthi uphakamise "indlu" yamashiya. Futhi ngenxa yalokho, "isimo sobuso" "sengane" siyavela. Umnikazi wenhliziyo yetshe kuphela ongamelana nokubukeka okunjalo.

Sihlelwe ngendlela yokuthi ekuphenduleni ukubukeka okunjalo, kunesifiso esicishe singenakuvinjelwa sokuvikela lowo osibheka kanjalo.

Ngaphezu kwalokho, “isimo sobuso” esinjalo silingisa isimo sobuso babantu ngezikhathi zokudabuka. Futhi ngisho nezinja ezindala zifana nemidlwane ebukekayo.

Ake ngiphinde ngikukhumbuze ukuthi izinja zifunde ukungaboni ukubukeka komuntu njengosongo futhi zingabheka emehlweni ethu. Ngaphezu kwalokho, ukuxhumana kwamehlo okumnene, okungasongeli kukhuthaza ukukhiqizwa kwehomoni i-oxytocin, enesibopho sokwakheka nokuqinisa kokunamathiselwe.
