Akatswiri akutsimikiza kuti chifukwa cha luso lotere, agalu akhala chitsanzo chokhacho cha "nyama yanyama" (momwe akumvera mumunthu).
Agalu amamvetsetsa kuti mawonekedwe a nkhopeyi ali ndi matanthauzidwe osiyanasiyana. Komanso, ndizotheka kuzindikira osati pakati pa anthu omwe amawadziwa bwino. Komabe, pano sitikudziwa zomwe kutengera izi kumatanthauza kwa agalu, asayansi atero.
Mwambiri, nyama zimagwirizanitsa nkhope zoseketsa ndi zina zabwino komanso zoyipa ndi zoyipa, akutero Ludwig Huber wa University of Veterinary Medicine ku Vienna.
Pa kafukufukuyu, zithunzi ziwiri za theka la nkhope ya munthu yemweyo zidawonetsedwa pazenera. Galu adakumbukira nkhope ndikuwonetsa zakukhosi. Kenako, ndikukhomera mphuno yake pa theka lina la nsalu yotchinga, adasankha nkhope yoyipa kapena yokoma. Pankhani ya kusankha koyenera, galuyo adalandira gawo la chakudya.
Ndikofunika kudziwa kuti omwe ali ndi miyendo inayi sanasamale za nkhope ngati panali yankho loyipa ngati yankho lolondola. Mwinanso izi zimachitika chifukwa chakuti agalu azolowera kuphatikiza nkhope zoyipa ndi mavuto, TV TV "Moscow 24" idatero.
Asayansi apeza kuti agalu, limodzi ndi anthu komanso anyani ena, ali mgulu la nyama zapamwamba zomwe ubongo wawo umatha kuzindikira ndi kusiyanitsa nkhope za abale ndi nthumwi zamitundu ina yazamoyo.
Othandizira a neurologysi adapeza gawo lapadera muubongo wa agalu zomwe zimawalola kusiyanitsa ndikukumbukira nkhope za eni ake ndi anthu ena, zomwe, mwachiwonekere, zidawathandiza m'mbuyomu "kubisa" munthu ndikukhala mnzake wapamtima.
Izi zidanenedwa ndi RIA Novosti potengera magazini ya PeerJ.
"Agalu, monga zimawonekera kwa aliyense, ndi nyama zachikhalidwe kwambiri, chifukwa chake zikuwonekeratu kuti amatha kusiyanitsa nkhope. Tidayesa kudziwa ngati aphunzira luso limeneli pamene moyo wawo ukupita patsogolo, kapena ngati ndi luso lamkati laubongo wawo ndi psyche." - adatero a Gregory Burns (a Gregory Berns) ochokera ku Emory University ku Atlanta (USA).
Burns ndi mnzake adawona kuti agalu ali mgulu laling'ono kwambiri lanyama zomwe zimatha kusiyanitsa nkhope pakuwona momwe ubongo wa "abwenzi apamtima" angapo amagwiritsira ntchito chithunzi cha maginito.
M'maphunziro am'mbuyomu, monga momwe a Burns amanenera, gulu lake lidakwanitsa kudzipatula madera angapo muubongo wa agalu omwe adayankhira zizindikiro zosiyanasiyana zakupezeka kwa munthu wodziwika m'chipindacho - mwachitsanzo, kununkhira kwake kunali kwamphamvu kuposa kununkhira kwa anthu ena komanso agalu wamba.
Kupeza kumeneku kunapangitsa asayansi kuganiza kuti ubongo wa agalu umatha kupangika makamaka kuti uzithana ndi anthu komanso kusinthidwa kuti ukhale moyo wamunthu. Anayesa chiphunzitsochi powona momwe agalu amachitikira akakhala anzawo komanso alendo, abale awo komanso zinthu zina zopanda moyo.
Kuti tichite izi, wofufuzayo anati, sizinali zazing'ono, chifukwa nthawi zambiri agalu samalabadira chithunzi cha mbali ziwiri pakompyuta ndipo amakonda kuyang'ana zinthu za dziko lenileni. Pazifukwa izi, nyama zisanu ndi imodzi zokha ndizo zomwe zidatenga nawo mbali pazoyesazi, zomwe zingayambitse kudandaula kuchokera kwa asayansi ena.
Komabe, zotsatira zake, malinga ndi Burns, zinali zoonekeratu komanso zosagwirizana - agalu akamayang'ana zithunzi kapena makanema omwe akukhudzidwa ndi anthu kapena abale, gulu lapadera la ma neurons "linatseguka" pamakina awo osakhalitsa, omwe sanawonekere nthawi zomwe nyama zinkayang'ana mipando yosiyanasiyana kapena zinthu zina zopanda moyo.
Kuphatikiza apo, monga wasayansiyo akutsimikizira, nkhope za anthu ndi agalu sizinayambitse kuchitapo kanthu pakukondweretsa kapena zigawo zina za ubongo. Izi zikusonyeza kuti "abwenzi apamwamba kwambiri a munthu" amatha kuzindikira nkhope, koma sanapeze chifukwa champangidwe wokhudzana ndi mawonekedwe a munthu komanso mwayi wopeza chakudya kapena zinthu zina zofunika kwa galu.
Chifukwa chake, Burns ndi mnzake adatha kupeza chinthu chinanso, chomwe, pamodzi ndi kuyang'ana kwa eni ake, kupukusa mafuta ndi kudya zakudya za anthu, adathandizira "abwenzi apamtima a anthu" kuti azolowere moyo wokhala pagulu la anthu.
Kodi galu wanu amazindikira zotengeka?
Yesani kuyesa nyumba. Khalani pafupi ndi galu wanu ndikumwetulira kwambiri. Amatsitsimutsa makutu ake ndikuyamba kugwedeza mchira wake. Kenako tembenukani ndikumuyang'ana ndi frown. Galu wanu amatha kupangitsa kuti awonekere olakwa nthawi yomweyo.
Kutha kuwerenga zolinga ndi malingaliro kumaso ndichida chofunikira pakupulumuka. Agalu akamachita bwino izi, amakhala ndi mwayi wotetezeka, pogona ndi chakudya kwa munthuyo. Mu 2015, akatswiri a sayansi ya zinthu zachilengedwe anapeza kuti kuyanjana pakati pa bambo ndi galu kunatheka chifukwa chakuti pamlingo wambiri wa biochemical adagwiritsa ntchito kachipangizo kamene kamathandizira kulumikizana kwachilengedwe - monga pakati pa mayi ndi mwana. Kuyanjana kwambiri pakati pa galu ndi munthuyo kumatsimikiziridwa ndi "mahoni achikondi" oxytocin.
