Ososayensi bathole ukuthi ingane izuza ukuhlakanipha kukabani.
– Uhlakaniphile ngobani? - abangani babuza indodana yami ngothando lapho, eminyakeni emihlanu nengxenye, ibatshela itafula lokuphindaphinda ngesishiyagalolunye.
Yiqiniso, ngalo mzuzu mina nomyeni wami siyamamatheka ngokuthopha. Kodwa manje sengilazi iqiniso. Kodwa ngeke ngimtshele umyeni wakhe. Ngizokutshela. Ingane izuza ukuhlakanipha kunina kuphela. Ubaba unesibopho kwezinye izimfanelo - izici zomlingisi oyinhloko, isibonelo. Kufakazelwe Ososayensi!
Lezi zifundo zenziwe ngochwepheshe abavela eJalimane (University of Ulm) naseScotland (Social Council for Medical Research and Public Health Glasgow). Futhi ukuze uqonde ukucabanga kwabo, kuzodingeka ukhumbule isigaba sofuzo esivela kubhayoloji yesikole.
Ngakho-ke, siyazi ukuthi umlingiswa, ukubukeka, kanye nengqondo yengane, kwakha izakhi zofuzo zabazali bayo. Futhi i-X chromosome inesibopho sofuzo lobuhlakani.
“Abesifazane banama-X chromosome amabili, okungukuthi, banamathuba aphindwe kabili okudlulisela ukuhlakanipha kwabo enganeni,” bayaqiniseka ososayensi. - Ngesikhathi esifanayo, uma izakhi zofuzo "zobuhlakani" zidluliselwa ngesikhathi esisodwa kubazali bobabili, khona-ke ubaba ulinganisiwe. Kusebenza ufuzo lukamama kuphela.
Kodwa asiluyeke ulibofuzo lodwa. Bukhona nobunye ubufakazi. Ngokwesibonelo, abaseScots benza inhlolovo enkulu. Kusukela ngo-1994, baye baxoxa njalo nentsha engu-12 ephakathi kweminyaka engu-686 nengu-14. Kwacatshangelwa izici eziningi: kusukela ebala lesikhumba kuya kwezemfundo. Futhi bathola ukuthi indlela eqinisekile yokubikezela ukuthi i-IQ yengane izoba yini ukukala ukuhlakanipha kukamama wayo.
“Eqinisweni, ihluke kubo kuphela ngesilinganiso samaphuzu angu-15,” kufingqa ososayensi.
Nalu olunye ucwaningo, kulokhu oluvela eMinnesota. Ubani ochitha isikhathi nengane kaningi? Ubani omculela izingoma, adlale naye imidlalo yokufundisa, amfundise izinto ezahlukene? Kuyafana lokho.
Ochwepheshe bayaphikelela: ukunamathela ngokomzwelo kwengane nomama nakho kuhlobene ngokungaqondile nokuhlakanipha. Ngaphezu kwalokho, izingane ezinjalo ziphikelela kakhulu ekuxazululeni izinkinga futhi zisabela kalula ekuhlulekeni.
Ngokuvamile, kungakhathaliseki ukuthi izazi zezakhi zofuzo nezazi zezenhlalo zazizama kangakanani, azizange zithole “imikhondo” yomuntu ezindaweni zobuchopho ezibhekele ukuhlakanipha, ukucabanga, ulimi nokuhlela. Kodwa bajahe ukuqinisa obaba: indima yabo nayo ibaluleke kakhulu. Kodwa kwezinye izindawo. Izakhi zofuzo zesilisa zithinta uhlelo lwe-limbic, okuthi, ngokusho kososayensi, lunesibopho sangempela sokusinda: lulawula ukuphefumula, ukugaya. Uphinde alawule imizwa, indlala, ulaka kanye nokusabela kocansi.
Ngokuvamile, ukuthuthukiswa kobuhlakani kuncike kufuzo ngamaphesenti angama-40-60. Futhi-ke - ithonya lemvelo, izimfanelo zomuntu siqu kanye nokukhuliswa. Ngakho nakekela izingane zakho futhi okusele kuzokulandela.
