Labemi - is ...

Labemi - bamo besive sinye iintlobo zebhayoloji, ekwaziyo ziyazalana ngokukhululekileyo yaye pool sofuzo eqhelekileyo. Zezinambuzane amandla, ukufa, ukuchuma, amandla, ingxinano areal. isakhiwo Abemi olubandakanya umlinganiselo amadoda kunye nabasetyhini, ubudala, inkqubo nokwabiwa lwesithuba.

ubungakanani ndawo imiswe ngokungqinelana ne kwirediyasi yunithi (ngamnye) umsebenzi kwaye imele umgama phakathi ngongoma kunye kwinqanaba lokufa wokuzalwa abantu abaninzi. Umzekelo, licilikishe kwirediyasi kweemitha amathathu, muskrat - amalunga namakhulu amane, umvundla kunye Ndinjengentaka - neekhilomitha ezintathu. Kwizityalo, ubukhulu kummandla imiswe ngokungqinelana umgama, leyo iimpukane umungu. Umzekelo, pine radius umsebenzi malunga elinamanci mabini, kunye nombona - malunga neshumi elinesihlanu eemitha.

Le ndawo kunye nokumila ndawo kwimeko nganye imiswe ngokungqinelana iimpawu iindawo zomhlaba ohlayo. Enye into ebalulekileyo yile iimpawu intrapopulation ahlukile, kwakunye ngokwezelizwe (kagunyaziwe) abantu zonxibelelwano.

Amaninzi, ezi ntlobo awodwa, njengoko geographical, eziphilayo, zendawo.

umnxeba Environmental le iseti ngabantu ezihlala kwinkqubo efanayo. Imida ungqamane imida ecosystem ngokwayo, echazwa uhlaza, sisityalo ekuhlaleni.

Labantu bendawo - iseti zengingqi kweentlobo ezithile. Abantu abahlala eziphilayo ezahlukeneyo kwiindawo ezithile. Ngenxa yoko, abantu balapha zendlu Ndinjengentaka - ingqokelela inane abantu kuluntu akhiwe kumgama ozikilometa ngaphantsi kwe emithathu.

Geographic ebizwa iseti abantu, wangapandle ummandla kunye neemeko eyohlobo olulodwa ngokwendawo. Ukusuka ena ku Brest, umzekelo, wafumana iisethi imashumi mabini anesithoba kweziyi eziqhelekileyo. bakuyo Geographic - yinto zenyathi uhlanga indawo. Imizekelo yezinto ngaloo ukubonisa ukufana phenotypic.

Labantu (abantu) - le, kuqala kwiinto zonke, iyunithi esisiseko inkqubo zazivelela. Kunye nale nto ke unit main lwendawo uhlobo oluthile. Ngenxa yoko, abantu ingachazwa yingqokelela abantu, hayi nje babe kwintsimi ethile (space), kodwa iyakwazi ukudlalwa ixesha elide. labantu Integrity amagama kwindaleko enxulumene kakhulu panmixia (hybridization free), nto leyo okukwiqondo elithile ngaphakathi ezininzi iindidi ngaphezulu phakathi kweentlanga angabamelwane. Kunye nale, nangona ngengqibelelo, a owahlukeneyo labemi imikhwa yemfuza. Iimpawu eziphambili lweentlobo ayinakutshintshwa zemfuza.

Kukho kucalulo yabantu kwaye ukusuka kwindawo yonyango ngayo.

Umzekelo, uluhlu oluvaliweyo abantu ekwanti. Kulo mzekelo, abantu omnye uyazimela abanye ngokwesini.

Kukwakho iseti ogqibeleleyo ngabanye. Kulo mzekelo, cinga panmictic ezingenzeka (ekwaziyo ziyazalana) abemi ukuba amandla aphezulu, isizukulwana okuqhubekayo. Loo ingqokelela eziphilayo ayichaphazeleki uxinzelelo ukuguquka, imiba yangaphandle ngokukhethwa zendalo. Ingcamango kwabantu efanelekileyo lisetyenziswa yokulinganisa chavelela.

Abantu zohlobo olufanayo kunokuba zemfuza twatse. Kule meko sithetha ngayo kwabantu isogenic.

Wokuhlangana kungaba evulekile. Kulo mzekelo, iintaka zifuduka bazise yemfuza yakhe entsha.

labantu amagciwane luluhlu uhlobo oluthile iiseli.
