Peb cov tib neeg belongs rau hom "homo sapiens", uas nyob rau hauv lem muab faib ua haiv neeg. Cov subspecies no tuaj yeem txhais tau tias yog cov pab pawg lom neeg uas muaj qee qhov sib txawv ntawm cov yam ntxwv morphological (xim ntawm lub qhov muag, plaub hau, tawv nqaij; lub ntsej muag, qhov ntswg, daim di ncauj, lub cev proportions), uas yog keeb kwm thiab tshwm sim los ntawm ib puag ncig hauv lub cev. yav dhau los. Txhua tus ntawm lawv muaj ib qho keeb kwm, tsim thiab qhov chaw ntawm keeb kwm. Cov kws tshawb fawb paub qhov txawv ntawm peb pawg loj tshaj plaws: Caucasoid (haiv neeg dawb), Mongoloid (daj) thiab Negroid (dub). Txawm hais tias, feem ntau, muaj ntau dua 30 ntawm lawv.
Ntawm thaj chaw ntawm Africa, Australia thiab Oceania nyob radically "tsaus" cov neeg. Lawv muaj lub cev sib luag, ntev-legged, tawv dub lossis xim av, thiab ob lub qhov muag thiab cov plaub hau ntawm tib xim (nyuaj thiab curly), nrog rau daim di ncauj tuab thiab lub qhov ntswg dav, flattened. Negroids yog Africans, Australians thiab Melanesians. Tam sim no, lawv coob leej nyob hauv tebchaws Amelikas, txij li thaum lub sijhawm qub qhev cov tswv tau yuam lawv tawm hauv tebchaws Africa. mos ncaj (qee zaum wavy) plaub hau,cov xim uas tuaj yeem yog los ntawm nplej mus rau xim dub; qhov muag kuj tuaj yeem sib txawv: los ntawm xiav mus rau xim av; nqaim ntev qhov ntswg thiab daim di ncauj nyias. Lawv nyob hauv Europe, North Africa thiab thaj chaw ntawm Asia. Nyob rau hauv ib puas xyoo tsis ntev los no, cov haiv neeg nyob sab Europe tau nthuav dav thoob plaws hauv Asmeskas, New Zealand thiab Australia.
hom thib peb yog Mongoloids. Lawv muaj cov tawv nqaij daj, lub ntsej muag dav,
ncaj cov plaub hau ncaj, qhov muag nqaim, lub ntsej muag zoo nkauj, lub qhov ntswg luv thiab daim di ncauj nruab nrab. Lawv Ameslikas nyob hauv Asia, tab sis, zoo li lwm tus, lawv maj mam nthuav lawv qhov chaw nyob.
Vim tias txhua haiv neeg ntawm tib neeg muaj tib lub hauv paus chiv keeb thiab tau rov sib xyaw ua ke txhua lub sijhawm, nws tsis tuaj yeem tsim ib thaj tsam meej. nruab nrab ntawm lawv, yog li muaj ntau pawg sib xyaw.
Cov pawg neeg saum toj no tau tsim li cas? Cov xeeb leej xeeb ntxwv ntawm txhua tus ntawm lawv nyob rau hauv ntau qhov chaw, thiab nyob rau hauv lub sij hawm ntev ntawm tej yam ntuj tso yam, vim hais tias ntawm ib tug tshwj xeeb kev nyab xeeb, peculiar morphological nta tau kho nyob rau hauv tib neeg. Yog li, haiv neeg dawb tshuav nws lub qhov ntswg nqaim (kom sov huab cua) thiab tawv nqaij dawb rau huab cua txias thiab lub hnub me me.
Tom qab kev faib tawm zoo li no, qee cov kws tshawb fawb tau hais tias hauv tib neeg lub neej, kev tsav tsheb tom qab kev txhim kho yog kev tawm tsam kom muaj sia nyob, thiab kev ua tsov rog no yuav tsum tau ua haujlwm ntawm tib neeg hom, thiab nws yog raws li kev cai ntawm ntuj tsim. Lawv ntseeg tias haiv neeg dawb yog cov neeg muaj roj ntsha muaj zog dua piv rau lwm tus, thiab tsis paublawv txoj kev sib koom siab. Yog li, kev ntxub ntxaug tau tshwm sim nrog nws qhov kev faib ua "siab dua" thiab "qis" cov neeg, uas xav tias yog qhov tseeb ntawm kev tua neeg fascist thiab kev ua phem rau cov neeg African thiab Asians.
