Kusankhidwa kwachilengedwe komanso kochita kupanga

Kusamalira pakhomo ndi chinthu chodabwitsa. Panthawi yoyesera nkhandwe, adapeza kuti ngati nyama zimasankhidwa chifukwa cha makhalidwe monga kusakhalapo kwachiwawa ndi mantha kwa anthu, izi zingayambitse kusintha kwina. Kuyeserako kunapangitsa kuti zitheke kukweza chophimba chachinsinsi pa ntchito yoweta agalu.

Pali chodabwitsa choweta agalu. Mitundu yambiri yomwe timadziwika nayo masiku ano idawonekera m'zaka 2 zapitazi. Izi zisanachitike, mitunduyi inalibe mawonekedwe awo amakono. Zimapangidwa ndi kusankha kochita kupanga potengera mawonekedwe ndi machitidwe.

Zinali za kusankha komwe Charles Darwin analemba m'buku lake la Origin of Species, akujambula fanizo la kusankha ndi chisinthiko. Kuyerekezera koteroko kunali kofunikira kuti anthu amvetsetse kuti kusankha kwachilengedwe ndi chisinthiko ndi kufotokozera komveka kwa kusintha komwe kwachitika ndi mitundu yosiyanasiyana ya nyama pakapita nthawi, komanso kusiyana komwe kulipo pakati pa mitundu yofananira ya nyama zomwe zasintha kuchokera ku zibale zapamtima kupita kudziko lina. zakutali kwambiri. achibale.

Koma tsopano anthu ochulukirachulukira akulolera ku lingaliro lakuti agalu monga mtundu sali chotulukapo cha kusankha kochita kupanga. Lingaliro lakuti agalu ndi zotsatira za chisankho chachibadwa, "kudzikonda" kumawoneka kowonjezereka.

Mbiri yakale imakumbukira zitsanzo zambiri za udani pakati pa anthu ndi mimbulu, chifukwa mitundu iwiriyi inkapikisana ndi chuma chomwe sichinali chokwanira. Chotero zikuwoneka kuti sizomveka kwenikweni kuti ena mwa anthu achikale adzadyetsa mwana wa nkhandwe ndipo kwa mibadwo yambiri amapanga mimbulu yamtundu wina yoyenera kugwiritsidwa ntchito.

Ambiri mwina, zomwezo zinachitika kwa mimbulu monga nkhandwe mu kuyesera wotchedwa Dmitry Belyaev. Njira yokhayo, ndithudi, inali yotalikitsidwa kwambiri m'kupita kwanthawi ndipo sichimayendetsedwa ndi munthu.

Kodi munthu adaweta bwanji galuyo? Kapena galu adaweta bwanji munthu?

Akatswiri ofufuza za majini sagwirizanabe za nthawi yeniyeni imene agalu anawonekera: zaka 40 zapitazo kapena zaka 000 zapitazo. Mwina izi zili choncho chifukwa chakuti zotsalira za agalu oyambirira omwe amapezeka m'madera osiyanasiyana amachokera ku nthawi zosiyanasiyana. Koma pambuyo pa zonse, anthu a m’madera amenewa anali ndi moyo wosiyana.

M'mbiri ya anthu okhala m'malo osiyanasiyana, posakhalitsa panafika mphindi pamene makolo athu anasiya kuyendayenda ndikuyamba kupita ku moyo wokhazikika. Alenje ndi osonkhanitsa anakonza zisankho, kenako n’kubwerera ndi nyama kumalo awo kumene ankakhala. Ndipo chimachitika n’chiyani munthu akakhazikika pamalo amodzi? M'malo mwake, yankho limadziwika kwa aliyense amene adakhalapo m'midzi yapafupi ndikuwona mapiri akuluakulu a zinyalala. Inde, chinthu choyamba chimene munthu amayamba kukonza ndi kutaya.

Zakudya za anthu ndi mimbulu panthawiyo zinali zofanana, ndipo munthu yemwe ali wolusa kwambiri akataya chakudya chotsalira, zotsalirazi zimakhala zosavuta, zokopa kwambiri mimbulu. Pamapeto pake, kudya zotsalira za chakudya cha anthu sikoopsa kuposa kusaka, chifukwa nthawi yomweyo ziboda "sadzawulukira" pamphumi panu ndipo simudzagwidwa ndi nyanga, ndipo anthu safuna kuteteza zotsalira. .

Koma kuti muyandikire malo okhala anthu ndikudya zotsalira za chakudya cha anthu, muyenera kukhala olimba mtima kwambiri, mwachidwi komanso nthawi yomweyo osakhala ankhanza kwambiri kwa anthu ngati nkhandwe. Ndipo izi ndizofanana ndi zomwe nkhandwe zinasankhidwa mu kuyesa kwa Dmitry Belyaev. Ndipo mimbulu m’magulu amenewa inapereka makhalidwe amenewa kwa mbadwa zawo, n’kukhala pafupi kwambiri ndi anthu.

Kotero, mwinamwake, agalu si zotsatira za kusankha kochita kupanga, koma kusankhidwa kwachirengedwe. Palibe munthu amene anaganiza zoweta galu, koma mimbulu yochenjera inaganiza zokhala pafupi ndi anthu. Mimbulu yatisankha. Ndiyeno anthu onse ndi mimbulu inazindikira kuti panali phindu lalikulu kuchokera kumalo oterowo - mwachitsanzo, nkhawa za mimbulu zinkakhala chizindikiro cha kuyandikira ngozi.

Pang’ono ndi pang’ono khalidwe la anthu a nkhandweli linayamba kusintha. Ndi chitsanzo cha nkhandwe zoweta, tikhoza kuganiza kuti maonekedwe a mimbulu anasintha, ndipo anthu anaona kuti adani m'dera lawo anali osiyana ndi amene anakhalabe kuthengo. Mwina anthu ankalolera kwambiri mimbulu imeneyi kuposa amene ankapikisana nawo pakusaka, ndipo uwu unali mwayi wina wa nyama zimene zinkasankha moyo pafupi ndi munthu.

Kodi chiphunzitsochi chingatsimikiziridwe? Tsopano zawoneka nyama zambiri zakutchire zomwe zimakonda kukhala pafupi ndi anthu komanso kukhala m'mizinda. Pamapeto pake, anthu amalanda malo ochulukirachulukira kwa nyama zakutchire, ndipo nyama zimafunika kuthawa kuti zipulumuke. Koma kuthekera kwa malo oterowo kumapangitsa kuchepa kwa mantha ndi nkhanza kwa anthu.

Ndipo nyama zimenezi zikusinthanso pang’onopang’ono. Izi zikutsimikizira kafukufuku wa kuchuluka kwa agwape amtundu woyera, wochitidwa ku Florida. Agwape kumeneko anagawidwa m'magulu awiri: zambiri zakutchire ndi otchedwa "tauni". Ngakhale kuti agwape amenewa sankadziwika ngakhale zaka 30 zapitazo, tsopano ndi osiyana. Agwape a “m’tauni” ndi aakulu, osaopa anthu, ali ndi ana ambiri.

Pali chifukwa chokhulupirira kuti posachedwapa chiŵerengero cha mitundu ya “zoŵeta” chidzakula. Mwinamwake, molingana ndi dongosolo lomwelo, malinga ndi zomwe adani oipitsitsa a munthu, mimbulu, kamodzi anasandulika kukhala mabwenzi apamtima - agalu.
