Thawj qhov qhia txog kev sib raug zoo ntawm choanoflagellates thiab Metazoa tshwm sim thaum nruab nrab mus rau lig- 1800s thaum cov kws tshuaj ntsuam xyuas tau sau tseg qhov zoo ib yam ntawm choanoflagellates rau lub dab tshos (los yog ' choanocytes') ntawm daim txhuam cev.
Puas sponges evolve los ntawm choanoflagellates?
Sponges evolved li no los ntawm a craspedid-zoo li qia choanoflagellate.
choanoflagellates hloov zuj zus los ntawm dab tsi?
Choanocytes saib thiab ua yeeb yam zoo li choanoflagellates, ntau npaum li ntawd qee cov kws tshawb fawb tau pom nyob rau xyoo 1980 thiab 90s tias choanoflagellates tej zaum yuav yog cov tsiaj uas hloov zuj zus los ntawm sponges thiab tom qab ntawd yooj yim mus rau ib leeg.
Lub hauv paus ntawm Multicellularity yog dab tsi?
Thawj pov thawj ntawm ntau lub cellularity yog los ntawm cyanobacteria zoo li kab mob uas nyob 3–3.5 billion xyoo dhau los. Yuav kom rov tsim dua tshiab, cov kab mob sib txawv tiag tiag yuav tsum daws qhov teeb meem ntawm kev tsim tawm tag nrho cov kab mob los ntawm cov kab mob (piv txwv li, phev thiab qe hlwb), qhov teeb meem uas tau kawm hauv evolutionary kev loj hlob biology.
Tus tsiaj thawj zaug hauv ntiaj teb yog dab tsi?
A comb jelly. Lub evolutionary keeb kwm ntawm lub zuag jelly tau nthuav tawm cov ntaub ntawv xav tsis thoob txog lub ntiaj teb thawj tsiaj.
