Chifukwa mtundu woyera imatengedwa apamwamba

umunthu wathu wa mitundu "Homo sapiens", limene pamapeto lagawidwa mafuko. subtypes izi zikhoza limanenedwa ngati gulu zamoyo ndi ena osiyana makhalidwe morphological (mtundu wa maso, tsitsi, khungu, mawonekedwe nkhope, mphuno, milomo, thupi kufanana), amene ali cholowa, ndipo anatuluka mchikakamizo cha chilengedwe mu kutali kale. Aliyense ali ndi umodzi chiyambi, mawonekedwe ndi malo amene anachokera. Asayansi apeza mitundu itatu waukulu kwambiri: Caucasoid (woyera mtundu), Mongoloid (chikasu) ndi Negroid (wakuda). Ngakhale ambiri, pali anthu oposa 30.

Mu Africa, Australia ndi Oceania moyo ukasintha "mdima" anthu. Iwo ali wochepa yaitali miyendo thupi, khungu zakuda kapena zofiirira ndi chomwecho maso mtundu ndi tsitsi (lopotana ndi zovuta), ndipo milomo wandiweyani komanso lowombedwa ndi mphuno mosabisa. Negroid ali ku Africa, Australia ndi Melanesians. Panopa, ambiri a iwo amakhala America, monga masiku a slaveowners akale mokakamiza kuwatengera ku Africa.

White mtundu amadziwika owayimilira kuyatsa kapena khungu penapake mdima; mizere zofewa (nthawizina corrugated) tsitsi zimenezi kwa tirigu wakuda; maso angakhalenso osiyana yabuluu zofiirira; yopapatiza yaitali mphuno ndi milomo woonda. Iwo anthu Europe, Africa North ndi ena a ku Asia. M'zaka za m'ma otsiriza mtundu European ambiri Zafalikira America, New Zealand ndi Australia.

Mtundu wachitatu - Mongoloids. Iwo khungu chikasu, lonse flattened nkhope, molunjika tsitsi lakuda, maso yopapatiza, cheekbones otchuka, kanthawi lathyathyathya mphuno ndi milomo pakati. Poyamba ankakhala Asia, koma, monga ena, pang'onopang'ono anawonjezera malo awo.

Popeza mitundu ya anthu ndi chiyambi chomwecho mobwerezabwereza wothira mnzake nthawi zonse, mzere pakati pa iwo sangakhoze anakhazikitsa choncho pali zosiyanasiyana amisinkhu yosiyanasiyana.

Monga tanena magulu womwewo wa anthu inakhazikitsidwa? Mbadwa za aliyense wa iwo anali malo osiyana, ndipo nthawi yaitali zinthu zachilengedwe chifukwa nyengo yeniyeni, anali atathana chosiyana makhalidwe morphological anthu. Choncho, mtundu woyera alitcha ake yotundumukira kunja kwa mpanda mphuno yopapatiza (mpweya kukhala ofunda) ndi woyera kozhoy ozizira nyengo ndi wofatsa dzuwa.

Pambuyo gulu ili, asayansi ena amanena kuti anthu amene ali anakopa chitukuko cha kulimbana kukhalapo, Komanso, nkhondo imeneyi iyenera anachita pakati pa mitundu ya anthu, ndipo potengera malamulo a chilengedwe cha uthunthu. Iwo ankakhulupirira kuti woyera mtundu - anthu biologically wamphamvu kuposa ena, ndipo sanazindikire mgwirizano wawo wamba. Motero, tsankho ndi kugawikana ake mu "apamwamba" ndi anthu "otsika," amene ankati wolungama chiwonongeko Nazi ndi kulamulira mwankhanza Africa ndi ku Asia.

Pomaliza, kulephera kwa mfundo tsankho anali kumatha kafukufuku (rasovedeniem), amene anaphunzira mbiri ya mapangidwe a mitundu anthu ndi zizindikiro zawo.
