Puas tau txij li cov kws tshawb fawb tau ua raws cov chimp genome hauv 2005, lawv tau paub tias tib neeg sib koom txog 99% ntawm peb DNA nrog chimpanzees , ua rau lawv yog peb cov kwv tij nyob ze tshaj plaws.
Dhau li ntawm no, tsiaj txhu twg muaj DNA zoo sib xws rau tib neeg?
chimpanzees
Kuj Paub, ntau npaum li cas DNA ua tib neeg koom nrog miv? Miv zoo li peb ntau tshaj qhov koj xav. Ib txoj kev tshawb fawb xyoo 2007 pom tias kwv yees li 90 feem pua ntawm cov noob hauv Abyssinian domestic miv zoo ib yam li tib neeg . Thaum nws los txog rau protein-encoding noob, nas yog 85 feem pua zoo li tib neeg . Rau cov noob tsis-coding, nws tsuas yog kwv yees li 50 feem pua.
Ib yam li ntawd, nws tau nug, tib neeg puas koom DNA nrog tsiaj?
Nws lees paub tias peb cov txheeb ze nyob ze tshaj plaws yog chimpanzees thiab bonobos, nrog peb qhia ntau yam. Tab sis peb tsis tau hloov pauv ncaj qha los ntawm ib qho primates nyob niaj hnub no. DNA kuj qhia tau tias peb hom thiab chimpanzees diverged los ntawm ib tug poj koob yawm txwv hom uas nyob nruab nrab ntawm 8 thiab 6 lab xyoo dhau los.
Cov npua muaj feem cuam tshuam li cas rau tib neeg?
Cov npua yog genetic heev kaw rau tib neeg ” Schook piav qhia tias thaum peb saib ib npua los yog a tib neeg , peb tuaj yeem pom qhov txawv tam sim ntawd. "Tab sis, hauv kev nkag siab lom neeg, tsiaj tsis txawv ntau ntawm ib leeg - tsawg kawg tsis txawv li lawv tshwm sim," nws hais.

Leej twg yog tus txheeb ze ze tshaj rau tib neeg niaj hnub no?
Chimpanzees
Puas muaj DNA ntau npaum li cas tib neeg koom nrog cov tsiaj nyeg?
Kom meej meej, acorn worms tsis zoo li tib neeg; cov worms tsis muaj ceg tawv thiab ua pa los ntawm cov slits hauv lawv lub plab. Tab sis lawv sib koom kwv yees li 14,000 cov noob nrog tib neeg, cov kws tshawb fawb pom, suav nrog txog 70 feem pua ntawm tib neeg genome
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Lub teb chaws twg muaj tshaj 30 lab tus tib neeg nyob hauv qhov tsua?
Ntau tshaj 30 lab tus tib neeg hauv Suav teb nyob hauv av hauv qhov tsua. Kaum tawm lab hauv Suav teb tau mus hauv av - mus nyob. Ntau tshaj 30 lab Suav ua lawv lub tsev nyob hauv qhov tsua, raws li tsab ntawv ceeb toom tsis ntev los no los ntawm Los Angeles Times
