Indlela yokukhetha zendalo

Xa inkqubo yokukhetha zendalo labemi ukugcina nokuphucula abo bantu ezifaneleke kakhulu ukuba asinde kakhulu etshintshwe apha. Eli gama endiyenzileyo ngexesha elinye eqhelekileyo Charles Darwin. Yena wamazisa enokuthelekiswa ukhetho ngumntu , kwaye zibonisa ukuba, mgaqo, kuzo zombini ezi meko, inkqubo le efanayo. Umahluko kuphela kwizakhiwo ezithile ondixabisayo efunekayo okanye hayi - yokuhlala okanye abantu.

Ifomu yokukhethwa zendalo zihlelwa ngenxa kweekhrayitheriya ezininzi. typology Egqugqisileyo ecetywayo I. I. Shmalgauzenom. Ukuchaza iintlobo ukhetho zendalo, ukuba ngokusekelwe nangendlela oku kunempembelelo ngayo hexa okanye nozinzo usikhokele labemi. Inani labo umbuzo uhlala ayiphendulwanga. Kodwa ezinkulu isayensi yezinto eziphilayo nangoku ingqalelo iintlobo ezintathu zilandelayo yokukhetha zendalo: Sokuchitha (ephazamisayo), esi sikhokelo (ukuqhuba) kunye ozinzileyo. Le genotypes babe iintlobo ezahlukeneyo ngakumbi, kokukhona kungcono nkqubo lwenzeka.

Isiphumo yokukhethwa olutshintshayo uba siyabophelela Ngokuphambuka imiqondiso eqhelekileyo. Kuye kuchazwe kuqala Wallace Darwin. Kwimeko kwale ukhetho inikwa abo bantu uneempawu, ezihamba ngamandla kwicala elinye okanye elinye.

Oku kubonakala xa indawo eyandisiweyo okanye okusingqongileyo utshintsho. Emva koko ke izidalwa eziphilayo kufuneka ukutshintsha kwicala elithile, ukuba nokuchuma nokuhlala kwiimeko ezintsha. Umzekelo, ukuba ezanyisayo ezisentlabathini banyanzelwa ukuba baye kuhlala phantsi emhlabeni, ngokuthe ngcembe imilenze yabo ukumelana neemeko ezintsha zibe emgodini.

Ifom sizinze ngokukhethwa zendalo lujolise ekulondolozweni abantu abaye babonisa inkalo ethile kunye wononophelo kwaye ngaxeshanye ukutenxa abo ukuba ikude kakhulu kwisiqhelo. Ngokomzekelo, kusenokwenzeka ukuba baphile kwiintaka ukuba amaphiko ubungakanani standard yaye hayi kakhulu okanye ezinkulu nezincinane.

Action Ukukhetha ephazamisayo malunga yempembelelo emibini edlulileyo. Oku kwenzeka xa iimeko efanelekileyo ukwenzela uphuhliso oluqhubekayo umqondiso ekwimo yakhe ezigabadeleyo, kodwa hayi phakathi. Ngenxa yoko le fom okokuqala singaveli yedwa, kwaye nkqu ezintsha ezimbalwa. Ngoko ke, ukukhetha ephazamisayo inokuba unobangela, iintlobo ezintsha neze zikhona ngaphambili.

Kwindalo, ntonje imeko apho omnye kwaye ababodwa ohlala kwiindawo ezahlukeneyo. Ngako oko, amalungu ayo ziqhelana zabo ehlukene yayigcinwa eziphilayo.

Umzekelo ukukhetha ephazamisayo zamntu olwenziwe kuye kwafika kubo bonke ukuzama fruit. Emva kokuba zisukele ukuba ekhethiweyo kuphela abantu ukuba nokuba inani eliphezulu okanye ubuncinane ezifumaneka, amaqela amabini ngentsimbi ukusukela kwisizukulwana wamashumi amathathu, yahluke kakhulu omnye komnye, nangona baqhubeka hybridize kunye.

Ngaphandle iintlobo ezintathu eziphambili ibonwa eziphilayo, ukhetho ngokwesondo. Impembelelo yakhe ebalulekileyo. Ngapha koko, wonke umntu kufuneka ukuzivumelanisa kuphela kwaye asinde, kodwa ufana naye ukuba aqhubeke iintsapho zabo.

Kukho na awayefike ezimbini ukuchaza indlela amanyathelo ngokukhethwa ngokwesondo.

Ngokutsho libhinqa lokuqala ukhetha inkunzi kakade, kuba ikwazile ukuba baphile ekuvuthweni, nangona imbonakalo eliqaqambileyo. Oku kuthetha ukuba izakhi elungileyo lize lizidlulisele ukuya kwisizukulwana esilandelayo.

Hypothesis yesibini sicacisa ukhetho ngababini ezahlukeneyo. Ngokutsho kwakhe, iimazi iqabane eliqaqambileyo ukhetha libe umbala onomtsalane, ucinga ukuba isizukulwana esilandelayo kufuneka ukuba efanayo kubo, kwaye bakhetha nokuzala.

Ukongeza bathathu ezidweliswe ngasentla, kukho iintlobo ngamnye kunye neqela ngokukhethwa zendalo. Iinjongo zokuqala ukugcina abanye abantu abaye imiqondiso eziya kubavumela ukuba ukuphila nokuhlala phakathi bawo. Iqela iseke umgangatho, ilincedo lonke uhlobo.

Zonke iifom okhoyo ukhetho endalo ayikho ngokungakhethiyo,-ndenzile kanye, kodwa ngokuthe ngcembe, njengokuba ukusuka kwisizukulwana ukuya kwisizukulwana, abemi igcina iimpawu ezithile.
