Anthu kusanduka: anasiya kapena ayi?

Asayansi ambiri nkhawa za funso lakuti: "Kodi chisinthiko anthu anasiya"? Ambiri a iwo amakhulupirira kuti yankho lake liyenera kukhala inde. Ndithudi, ngati tikambirana ndondomeko monga kusankha zamoyo, mwina anthu akhoza kusintha kwathunthu anagonjetsa chilengedwe ndi luso kuzidyetsa wokha ndi ana awo? Ndipo ndi zamakono zachipatala, kukayikira kulikonse kutha - zinafika ungwiro wake.

Koma otere ndi mfundo zake ofooka. Chozemba sizikutanthauza kulibe. Modern anthu kusanduka - ndondomeko ndi wodekha kwambiri, choncho zovuta younikira mu nthawi yeniyeni. Komanso, pa kopanda wa malo kumabweretsa mapeto wosiyana ndi zotsatira za kafukufuku matupi a anthu.

Tanthauzo zosavuta mawu "chisinthiko" limanena kuti ndondomeko ya kusintha pafupipafupi alleles kwa anthu ndi pa nthawi. Ambiri mwa kusintha ngati ali m'malo a allele wina atamwa kusankha zamoyo. Kudziwa mmene anthu kusanduka ikuyenda, suffices kupeza zizindikiro allele kusintha pafupipafupi mu matupi athu ndi.

maphunziro Recent asiya kufotokoza zina mwa zitsanzo chidwi kwambiri pa zamoyo anthu amakono.

Choyamba - ichi ndi otchedwa okwera matenda. anthu atakhazikika mu madera lamapiri la dziko, anakumana ndi osakwanira mpweya mu mlengalenga. kulandidwa kotero kumatsogolera ku kufooka, chizungulire ndi tulo. Zikavuta kwambiri, zotsatira zake ndi kulisiya - edema m'mapapo mwanga ndipo anayamba imfa lolemera. Ndipo acclimatization akhoza kuchotsa mbali chabe ya zizindikiro.

Pa kafukufuku anatulukira kuti anthu zakwawoko la Tibet kuti ndinazolowera zikhalidwe maonekedwe a kusowa oxygen. Iwo wapezeka kuti kwambiri za Chitibeta magazi mpweya machulukitsidwe 10% poyerekeza ndi anthu wamba. Mbali imeneyi ndi ungwiro, choncho akhoza bwinobwino amati izo zimatengera mbewu umodzi.

Chitsanzo china chidwi ndi lactose tsankho. Ndi zimam'patsa yomwe imapezeka mu mkaka wa nyama. Iwo odzipereka mu thupi mothandizidwa ndi puloteni yapadera - lactase, amene amapangidwa intensively mu chaka choyamba cha moyo, kenako kaphatikizidwe wa mankhwala ndi kuchepa mphamvu. Ambiri mwa lactase wamkulu si apanga, tsono, lactose si odzipereka pafupifupi.

N'zosadabwitsa kuti American Indians, Avstraliyskie Aborigeny, okhala Asia South-East ndi kummwera kwa Africa akuvutika ndi kumwa mkaka lonse. Izo zimayambitsa bloating, kutsekula m'mimba, colic, kusanza, nseru. Pa nthawi yomweyo iwo akhoza kudya mkaka, monga ndondomeko nayonso mphamvu imaphwanya lactose.

Luso kugaya lactose mu akula anthu amene anagulidwa m'maiko awiri osiyana - Europe ndi Africa North. Pa nthawi yomweyo iwo ananyamuka payekhapayekha mzake ndipo amaoneka mu madera osiyana a matupi athu ndi. Izi kusintha awiri wakhala umboni wodalirika kuti zamoyo wa munthu akupitiriza.

mwapadera ayenera linaperekedwa kwa vuto la AIDS. A mliri wa matenda, yomwe inayamba mu 80s, ndi limodzi mwa zinthu zazikulu zaziwerengero pa mphindi. Pafupifupi 40 miliyoni Anthu. Amadwala matenda, ndi mliri pachimake kummwera kwa Africa, kumene pafupifupi 25% ya akulu kachilombo.

Iwo yapatsiridwa magawo ambiri a kusanduka anthu - koma kwambiri ndi kusankha zamoyo. Kuti iye anali mmodzi wa zinthu za zikamera wa AIDS, chifukwa umakhala ndi zina njira kusintha, atetezedwe ndi matenda. Ndipo, nthawi zambiri, nthawi, thupi anapanga mankhwala ena amene angathandize kuthana ndi matenda osachiritsika.

Chiyambi ndi zamoyo wa munthu anatenga kuposa zaka chikwi. Panthawi imeneyi, ife anawonjezeranso kukweza kwa ubongo, anasintha zinthu, tinayamba kuyenda molunjika, amaphunzira kukambirana. Tsiku lirilonse tiyenera kukhala, kupeza nzeru ndi luso latsopano ndi bwino kulimbana ndi matenda ndi kuyesera kuti akhale ndi moyo kuipidwa, kotero sitingathe kunena kuti zinthu anaima, ndi pang'ono m'mbuyo yake.
