Qhov sib txawv tseem ceeb ntawm homologous cov qauv thiab cov qauv vestigial yog cov qauv homologous yog cov qauv anatomically zoo sib xws hauv cov kab mob sib txawv uas sib koom cov poj koob yawm txwv thaum cov qauv vestigial yog cov qauv anatomical uas tau poob lawv cov txiaj ntsig rau lub cev.

Homologous cov qauv yog cov qauv vestigial yog ob hom qauv anatomical uas yog qhov tseem ceeb evolutionary. Homologous cov qauv yog cov qauv zoo sib xws tam sim no nyob rau hauv ntau yam kab mob uas yog los ntawm ib tug poj koob yawm txwv. Hauv qhov sib piv, cov qauv vestigial yog cov qauv uas tsis muaj txiaj ntsig rau cov kab mob thiab muaj qhov txo qis.

Homologous Structures yog dab tsi?

Homologous cov qauv yog cov qauv anatomical zoo sib xws tam sim no hauv cov kab mob sib txawv. Kev txheeb xyuas qhov kev hloov pauv ntawm cov qauv homologous no qhia tau tias cov kab mob no sib koom ua poj koob yawm txwv. Yog li ntawd, lawv yog evolutionarily ntsig txog kab mob. Piv txwv li, libs ntawm noog, khej, puav, whale thiab tib neeg yog homologous qauv. Tsis tas li ntawd, tes ntawm tib neeg, puav, miv thiab whale kuj yog homologous qauv.

Daim duab 01: Homologous Structures

Homologous cov qauv yuav ntiav cov haujlwm sib txawv txawm tias lawv zoo ib yam li anatomically. Ntxiv mus, lawv qhia txog kev hloov pauv ntawm cov kab mob sib txawv.

Vestigial Structures yog dab tsi?

Cov qauv vestigial yog cov qauv anatomical uas tsis siv lawm txawm tias lawv nyob hauv cov kab mob. Hauv cov lus yooj yooj yim, lawv yog cov khoom qub txeeg qub teg uas tau poob lawv cov txiaj ntsig zoo rau lub cev. Feem ntau, cov qauv no tau txo lawv qhov loj me nrog lub sijhawm thaum piv rau lawv qhov loj me. Tib neeg tailbone, appendix thiab whale pelvis yog ib co piv txwv ntawm cov qauv vestigial. Ntxiv mus, gill slits nyob rau hauv tib neeg thiab noog thiab txawj ntse hniav ntawm tib neeg kuj yog vestigial lug.

Txawm li cas los xij, cov qauv vestigial yog qhov kev hloov pauv tseem ceeb vim lawv muab cov lus qhia tseem ceeb txog kev hloov pauv ntawm cov kab mob lossis keeb kwm evolutionary.

Dab tsi yog qhov zoo sib xws ntawm Homologous Structures thiab Vestigial Structures?

  • Homologous cov qauv thiab cov qauv vestigial yog cov pov thawj evolutionary.
  • Lawv yog cov qauv anatomical tam sim no hauv cov kab mob.

Qhov txawv ntawm Homologous Structures thiab Vestigial Structures yog dab tsi?

Homologous cov qauv yog cov qauv zoo sib xws uas muaj nyob hauv cov kab mob sib txawv. Ntawm qhov tod tes, cov qauv vestigial yog cov qauv anatomical uas tsis muaj txiaj ntsig rau lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm homologous cov qauv thiab cov qauv vestigial. Tsis tas li ntawd, homologous cov qauv muab pov thawj rau kev hloov pauv txawv txav thaum cov qauv vestigial muab cov lus qhia rau cov keeb kwm evolutionary ntawm lub cev. Qhov no yog lwm qhov sib txawv ntawm homologous cov qauv thiab cov qauv vestigial.

Summary – Homologous Structures vs Vestigial Structures

Homologous cov qauv thiab cov qauv vestigial yog ob hom qauv anatomical uas yog qhov tseem ceeb ntawm kev hloov pauv. Homologous cov qauv yog cov qauv anatomically zoo sib xws tam sim no nyob rau hauv ntau yam kab mob uas muaj feem xyuam nrog evolutionarily. Hauv qhov sib piv, cov qauv vestigial yog cov khoom qub qub uas tsis muaj txiaj ntsig rau lub cev. Ntxiv mus, lawv qhov ntau thiab tsawg tau txo nrog lub sijhawm vim lawv tsis muaj haujlwm. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm homologous cov qauv thiab cov qauv vestigial.
