Systematics kwezilwane. Yini lena

Iplanethi yethu ecebile eziphilayo. Ngakho-ke, isikhathi eside kube nenkinga-akhawunti yakhe. Ngenxa yale njongo kukhona systematics. Kuyinto isayensi okhuluma cwaningo kanye nokubekwa ngezigaba zonke izilwane nezitshalo. Systematics kwezilwane esekelwe uhlelo umdwebo ngencazelo yawo wonke amalungu kwalo mbuso, kuhlanganise yokuqothulwa. Lolu hlelo njalo olusha.

Idatha entsha, ezisetshenziswa for ngezigaba, ukwakha amakilasi ezintsha zezilwane. Izinambuzane akhawunti yedwa ayisigidi zilwane. yokwenza iqembu isilwane kusivumela ukulandelela ukuthuthukiswa sabo emlandweni, okusho phylogeny.

Systematics kwezilwane ubonisa kwemvelo emhlabeni isilwane. Ngokusekelwe idatha yayo, ungasho ukuthi amafomu ngaphezulu okulula izilwane esikhundleni eziyinkimbinkimbi, okuyinto nezimo ezintsha kwemvelo.

Inqubo yokuziphendukela kwemvelo ngeke ibuyiselwe. Ngakho-ke, taxonomy isilwane kungaba ingxenye umsuka wezimfundiso jikelele silwane.

Noma yimuphi iqembu izilwane ihlukaniswe subgroups ezincane. Systematics ukwenza ngaphandle delineation izilwane, ukusatshalaliswa kwazo kulandzelana lokufanele amaqembu. Le nqubo uhlanganisa izigaba ezintathu.

Isinyathelo sokuqala siwukuba ukuchaza amaqembu kanye ukusatshalaliswa womama wakhe ikhefu. Ikakhulukazi alolu Kubalulekile kulawo maqembu ukuthi ayiqondakali kahle noma likhulu kakhulu. Lokhu kungabandakanya i-izinhlobo ezihlukahlukene zezinambuzane.

Isinyathelo sesibili siwukuthi ukuthola ukuxhumana phakathi ngamaqembu ahlukene okungase kukhonjwe ezinegunya. Kulesi morphological cwaningo, ukufana embryological ezibonisa ubudlelwano obuphakathi kwabo. Lesi sinyathelo kwenza kube nokwenzeka ukubona indlela izilwane washintsha phakathi kwemvelo.

Isigaba okwesithathu kuhilela isifundo izixhumanisi phakathi kwezinhlobo ezithile. Nasi ukuqhathanisa ezingeni labantu. Ivame kwenziwe amaqembu kahle wafunda. Ngesikhathi esifanayo ukuthola ukuthi kungani uhlobo oluthile ezihlukahlukene ngakho.

Animal systematics kunikeza isithombe esiphelele nezilwane ocebile planethi. Ngaphandle kwale sayensi ngeke kwenzeke umkhondo ngokunembile yonke inkambo yokuhle kwemvelo. Bekungeke yini kube semininingwane kungase kufaneleke, kodvwa kuphela ulwazi kunezinxushunxushu.

I taxonomy into taxon. Taxa - iqembu imiphakathi ukuthi luthathe indawo ethile ohlelweni ngezigaba.

taxon ngamunye has izigaba ezimbili ezinhle. Isigaba sokuqala sibizwa ngokuthi typology. Kuphela amanga ngesisekelo yayo izici morphological. Okungukuthi, uhlobo ngalunye has isakhiwo ayo noma uhlobo oluthile. Yilokhu inquma indawo yayo ohlelweni ngezigaba. Lo mqondo ibilokhu isetshenziswa ngokuphumelelayo isifundo futhi systematization uyathola kwezazi.

Eyesibili isigaba - begazi. Ukuze izinto eziphilayo, kuba ezifanele ngaphezulu. Lapha ayethanda kokuzalela zindlela. zinhlobo Hlukanisa reproductively behlukene yezinye izinhlobo.

Izinhlobo zezinto eziphilayo kwenza kube nzima ukulungisa ngezigaba. Akwenzeki njalo ukunquma ngokunembile ngabe izilwane akhethiwe kohlobo ehlukile noma nje umuntu izakhi, isici zensimu. Ngaphezu kwalokho, ezinye izinhlobo zawo namanje ishintshe bedle imvelo bangaphandle.

Kodwa, noma kunjalo, ukubaluleka taxonomy kwezilwane nawo njengomnyango mkhulu kakhulu. Inikeza ngalunye oluphilayo zakwazi igama layo ngo-Latin, okwenza kungabi ukudideka uma usebenzisa amagama enhlamba.

Namuhla taxonomy ihlangabezana inkathi entsha yentuthuko. Kusetshenziswe izindlela zezibalo, uhlelo lwekhompyutha, ukuhlaziywa DNA nezinye isayensi amaningi asathuthuka ezivumela ukuqonda kangcono nezilwane ocebile planethi.
