Ua tau koj saib evolution tshwm sim? Raws li rau ntau hom, tib neeg suav nrog, evolution tshwm sim ntau txhiab xyoo, nws tsis tshua muaj saib txheej txheem nyob rau hauv tib neeg lub neej.
Ib yam li ntawd, evolution tau soj ntsuam thiab sim li cas?
Cov kab mob tau txais txiaj ntsig zoo, uas tau dhau mus rau cov xeeb leej xeeb ntxwv. Evolutionary biologists siv cov txheej txheem systematic thiab xeem phylogenetic txoj kev xav rau saib thiab piav qhia txog kev hloov pauv hauv thiab ntawm cov tsiaj nyob rau lub sijhawm. Cov txheej txheem no suav nrog kev sau, ntsuas, kev soj ntsuam , thiab daim ntawv qhia txog qhov zoo rau evolutionary ntoo.
Tom qab ntawd, lo lus nug yog, dab tsi yog 5 qhov pov thawj ntawm evolution? Pov thawj rau evolution
- Anatomy. Cov tsiaj txhu tuaj yeem sib koom ua ke ntawm lub cev zoo sib xws vim tias qhov tshwj xeeb muaj nyob rau hauv ib qho qub poj koob yawm txwv (homologous qauv).
- Molecular biology. DNA thiab cov noob caj noob ces cuam tshuam txog kev sib koom caj ces ntawm lub neej.
- Biogeography.
- Fossils.
- Kev soj ntsuam ncaj qha.
Ib yam li ntawd, tej zaum koj yuav nug, peb puas tuaj yeem pom evolution hauv kev vam meej?
Coob leej xav tias evolution xav tau ntau txhiab lossis ntau lab xyoo, tab sis cov kws paub txog biologist paub nws ua tau tshwm sim sai. Tam sim no, ua tsaug rau genomic kiv puag ncig, cov kws tshawb fawb ua tau tiag tiag taug qab cov pej xeem-theem caj ces hloov pauv uas cim evolution hauv kev ua-thiab lawv tab tom ua qhov no hauv tib neeg.
Peb puas tuaj yeem soj ntsuam qhov tshwj xeeb?
Ib qho kev hloov pauv ua tau txaus. Los yog nws ua tau tshwm sim ntawm ntau, qeeb qeeb qeeb. Qhov no yog qhov kev tshwj xeeb uas evolution yog paub rau - qhov gradual hloov nyob rau hauv lub sij hawm uas cais hom. Tab sis tsuas yog vim peb ua tau tsis pom tag nrho kev tshwj xeeb cov xwm txheej pib mus rau qhov kawg tsis txhais hais tias peb ua tau 'tsis pom hom splitting.

Dab tsi tuaj yeem pom infrared telescopes pom?
Infrared telescopes tuaj yeem kuaj pom cov khoom txias dhau --- thiab yog li ntawd dhau lawm faint --- yuav tsum tau pom nyob rau hauv pom lub teeb, xws li cov ntiaj chaw, ib co nebulae thiab cov hnub qub xim av dwarf. Tsis tas li ntawd, cov hluav taws xob infrared muaj lub wavelengths ntev dua li pom lub teeb, uas txhais tau hais tias nws tuaj yeem dhau los ntawm cov pa roj thiab hmoov av tsis tau tawg
Koj puas tuaj yeem pom photosynthesis?
Dab tsi tshwm sim: Feem ntau peb tsis tuaj yeem pom cov pa oxygen tsim los ntawm photosynthesis, tab sis thaum nws tsim hauv qab dej nws zoo li npuas hauv dej. Cov no ntab mus rau hauv lub funnel thiab tshem tawm cov dej nyob rau hauv lub xeem raj
Koj puas tuaj yeem pom los ntawm graphene?
Nws yog qhov zoo tshaj plaws pob tshab, nqus 2.3 feem pua ntawm lub teeb uas tsaws rau ntawm nws, tab sis yog tias koj muaj ib daim ntawv dawb huv los muab piv rau, koj tuaj yeem pom tias nws nyob ntawd.' Qhov ntawd txhais tau tias koj tuaj yeem pom ib txheej ntawm atoms nrog koj lub qhov muag liab qab, yog tias lawv yog graphene
Koj puas tuaj yeem pom volcanoes hauv Hawaii?
Yog tias koj xav pom kev ua haujlwm hauv roob hluav taws, xws li cov lava ntws tawm thiab ua rau lub lava tawg, Hawaii lub Island loj yog tib qhov chaw pom hauv Hawaii. Kilauea thiab Mauna Loa ntawm Hawaii lub Island loj yog lub roob hluav taws kub, nrog Kilauea yog lub roob hluav taws Hawaii tshaj plaws hauv keeb kwm tsis ntev los no
Puas tuaj yeem pom fontanelle pulsating?
Qee lub sij hawm, qhov chaw mos rau saum koj tus menyuam lub taub hau yuav zoo li pulsating. Tsis tas yuav txhawj xeeb - qhov kev txav no zoo li qub thiab tsuas yog qhia txog qhov pom pom ntawm cov ntshav uas sib haum rau koj tus menyuam lub plawv dhia
