Tingamudziwe akusinthasintha anthu mtundu: umboni ndi zatsopano

Tingamudziwe akusinthasintha anthu mtundu analola kuti mbali yofunika kwambiri mu kukula kwa zamoyo zinachita kusintha. Lingaliro ndi katundu uyu kwa anatengera adzakhala m'nkhani yathu.

ndi masiyanidwe Kodi

Pansi masiyanidwe kumvetsetsa luso zamoyo kupeza zatsopano ndi katundu mu njira ya chitukuko cha munthu ndi mbiri yakale. Mundawu - zotsatira za anatengera awo chilengedwe. Choncho, masiyanidwe mu anthu a mtundu womwewo, lomwe limasonyeza zitsanzo m'munsimu muli chithunzi, zinachititsa zikamera wa mafuko anthu. Chigawo yopapatiza maso mongoloid ndi khungu lachikasu anapanga ndi kuliika pa genotype wa anthu amoyo m'chigawo Asian, kumene nthawi zonse kuwomba amphamvu mchenga mphepo. A wakuda chikopa Negroid chifukwa cha moyo m'chipululu African.

mitundu masiyanidwe

masiyanidwe mu chizindikiritso cha anthu a mtundu zasonyeza kuti zatsopano sangathe tinatengera. Izi zatsimikiziridwa mu njira zimenezo. michira Laboratory mbewa kuchekedwa ndipo anawoloka pakati pawo. anthu amenewo nthawi zonse anabadwa ana tailed. masiyanidwe amenewa amatchedwa sanali cholowa, kapena kusinthidwa kwa. Ngati latsopano zizindikiro okhudza chibadwa zida, kusintha kwa wina msinkhu, ndi masiyanidwe ndiye cholowa.

kusinthidwa masiyanidwe

Kumbukirani mwambi wa ana: "M'nyengo yozizira, woyera, ndi imvi m'chilimwe?" Ichi ndi chizindikiritso cha akusinthasintha anthu a mitundu chomwecho. Asayansi asonyeza kuti mbendera kusintha mtundu kalulu ubweya si mpweya kutentha, ndi kuchuluka kwa dzuwa. N'zosavuta kutsimikizira. Ngati nyengo ofunda mdima khola kapena aviary ndi hares, patapita kanthawi, iwo "kuvala malaya woyera."

Kusinthidwa masiyanidwe mwa anthu a mtundu umodzi wa mbewu tinganene kuti chitsanzo cha arrowhead. Chimakula mu madzi. Masamba a zomera, amene ali pansi pa madzi, ndi mawonekedwe riboni ngati, ndi pamwamba - muvi. Kusintha kwa zinthu zachilengedwe ndi kuwatsogolera ku kusinthidwa wa mawonekedwe awo. Ngati chomera lonse m'madzi, masamba onse a zinthu tepi.

Osati mbali zonse akhoza kusinthidwa mchikakamizo cha mmene chilengedwe. Mwachitsanzo, khungu zikhoza kusintha mchikakamizo cheza dzuwa. Koma pa gulu magazi si bwanji ndi zinthu aliyense. Mbali imeneyi, monga ena ambiri, ndi akatengela apabanja.

kusintha chibadwa

Kusintha okhudza zida majini, ndi cholowa. Iwo sadalira mmene chilengedwe komanso chifukwa recombination imene imachititsa kapena masinthidwe. Mbali awo ndi mwachisawawa ndipo sanali mbali mu chirengedwe. masiyanidwe mu chizindikiritso cha anthu a mtundu umodzi ndi zamoyo yogwirizana wakhala phunziro N. I. Vavilova Research wotchuka wasayansi. chifukwa awo linali lamulo ija magazi. Kwenikweni ake kwagona kuti kusintha cholowa amene anamuona pa mitundu ina, angathe kupezeka ena kumuyandikira mwa kubadwa. Mwachitsanzo, alubino Ndi mmene oimira magulu onse a inakhala. kusintha kumachitika onse nsomba ndi nyama.

Choncho, zamoyo chingakhale zosiyanasiyana. Izi chuma amatchedwa osakhalitsa. Iwo akhoza kukhala a mitundu iwiri. Kusinthidwa zimadalira mmene moyo wa anthu ndi wotetezedwa mwa genotype lapansi. Majini kusintha kugwirizana ndi kusintha zinthu cholowa. makhalidwe amenewa ali anadutsa pakati mibadwo. Osakhalitsa ndi chinthu chofunika kwambiri zikamera wa zimasintha zamoyo zinachita ndi kusinthika.
