Thiab thaum lub qe-ntws thiab feathered lub cev yog zoo nkauj txawv ntawm ib tib neeg , kwv yees li 60 feem pua ntawm cov noob qaib muaj a tib neeg gene sib. Txawm txiv tsawb kuj ceeb tias tseem qhia txog 60 feem pua ntawm tib yam DNA raws li tib neeg.

Tom qab ntawd, peb yuav faib DNA li cas nrog txiv tsawb?

Peb qhia feem ntau ntawm peb cov noob, uas ua rau DNA , nrog cov phooj ywg primates xws li chimpanzees thiab nrog rau lwm yam tsiaj xws li nas. Peb txawm muaj genes sib xws nrog cov txiv tsawb cog! Hauv qhov haujlwm no txhua yam khoom siv ua lub luag haujlwm tshwj xeeb hauv kev pab tshem tawm cov DNA los ntawm cov hlwb.

Ib tug kuj nug, pes tsawg DNA peb faib rau qaib? Kwv yees li 60 feem pua ntawm qaib genes sib raug zoo ib yam li tib neeg gene. Txawm li cas los xij, cov kws tshawb fawb tau pom ntau qhov sib txawv me me ntawm cov khub sib xws qaib thiab tib neeg cov noob, uas yog 75 feem pua zoo tib yam ntawm qhov nruab nrab, dua li ntawm cov nas thiab tib neeg cov noob caj noob ces, uas yog 88 feem pua zoo tib yam ntawm qhov nruab nrab.

Tsuas yog li ntawd, txiv tsawb puas muab 50 ntawm peb DNA?

Cov 50 feem pua ntawm cov neeg thiab txiv tsawb roughly txhais tau tias ib nrab ntawm peb genes muaj counterparts nyob rau hauv txiv tsawb . Piv txwv li, peb ob leeg muaj qee hom noob uas cov lej rau kev loj hlob ntawm tes, txawm tias cov no tsis tas ua los ntawm tib yam. DNA ua ntu zus.

Tib neeg puas koom DNA nrog cov nroj tsuag?

Cov kws tshawb fawb tam sim no lees paub tias nyob ib puag ncig ntawm ib feem ntawm tib neeg genome tuaj yeem hloov los ntawm nroj tsuag thiab lwm qhov chaw tom qab kev kawm loj dua. Cov txheej txheem uas cov noob kis tau yog txheej txheem hu ua kab rov tav hloov pauv (HGT), uas cov kab mob. qhia cov ntaub ntawv caj ces.
