Mua - ka hooiaio ana o ka mōʻaukala? Acaeoey o ke aloha ao

Kumu - o ke kino, i ke kumu nui cia o i i ua lilo ma ke kaʻina hana o ka evolutionary? Acaeoey o ka meaola. Ma lalo o kēia manaʻo ia mea i loko o ka 'ole, a ua emi mai ka e like me ka AYEIE hale a ma nā meaola hoemiia kūpono. Ua Ua manaoio ia vestigial nā loko ua lapuwale, akā, he nui o ia manawa kekahi mailuilu haalele paha kŘpa a na mea hana ka hoʻohana 'ana i ka hale a hana, loa paha manao no ka oi luna' pahu hopu.

I na makana evolution

Ma ka hoʻomaka o ka XIX kenekulia me nā'anatomia, iʻikeʻia like me nā morphology, i hanaʻia e like me he kuokoa liluwelo ka hoʻopaʻi e epa me ka mau kānāwai o? Acaeoey a me ka 'ole o nā loko ma ke kapakai a na nāʻano likeʻole o ka poʻe e ola ana mea ma kekahi mau kahua o ka hoʻonaʻauao o ka embryogenesis. Ka mea, ua lilo i ke kumu o ka hoike ana o kanaka kêia kanaka, mai ka 'ē aʻe poeikohoia o ka holoholona honua. Anatomia hōʻikeʻo ia nā loko ma kekahi meaola i oko ma ka nui a me ka shape. ka piha kaawale ana o kekahi o lakou, a kŘpa a poorly hoʻomohala ma e like me ka ia nā loko ma nā? ueo i ua ke kikohukohu. Underdeveloped nā loko i hele mai i ke kapaia rudimentary (mai ka Roma rudimentum -. "Ka loiloi mua ke kahua, ke kumu"). Ka mea, he mea lapuwale a me ka mea ma luna o ke ala i ka ia'na.

Kumu - he kino i i waiho i loko o ka papa o embryonic? Acaeoey, akā, e ho'ōla oki i ka Hawaiʻi. Ma ka makua palapala i loko o ka wā e hiki mai,ʻo ia noho i loko o ka underdeveloped moku'āina. Na kino a me na hapa o ia hiki ke loaʻa ma ka aneane na 'ano o ka holoholona a me ka mea kanu? Ueo. Ke hoʻohālikelike me ka homologous ( 'ano like) nā hale like meaola i kekahi underdeveloped a nele i kekahi mea nui wahi.

Aia i like kino, a ma ko kakou mau kino. No ka laʻana, ka mea akamai niho - o ka mua o ka ke kanaka. keia a me nā kino e like me ke kolu o ka lihilihi, a me epicanthus, tailbone, i paiiaʻi na cecum, pepeiao nāʻiʻo, a kiola lākou ka hoʻoneʻe, lauoho ma luna o ke kumu,ʻaoʻao. Ma huina, i ke kanaka kino hiki ke helu oi aku 100. He poe ka i koe iho o ua mau kino i i i ka like kūpuna pepa he piha-fledged helehelena.

Hoike o ka mōʻaukala? Acaeoey o ke aloha ao

Vestigial nā loko i ka hopena o kekahi loli ma ka puni 'ia i loko o ka palapala o ka kekahiʻano o ke ola haalele i kona nui no ka mea ola, a i nā hooki i kuleana pili i. Mākou e mai poina i ka mau 'ia mutations i alakai aku ai i ka ka ho'ēmiʻana i loko o ka nui o na kino likeʻole, hoʻonāwaliwali i ko lākou hana. Ma ka hanana o ka huakaʻi nā no ke ola o ka meaola undergo mutations i eliminated.

Ke 'ole, i mea ma ke kaʻina hana o ka hoʻopau, hai aku ai i ka manaʻo o "vestige". keia nona i ke kaʻina hana o ka evolution, a ua nānā 'ana ma luna o mutations, hereditary hou i loko o kekahi kanaka. Ma meaola me ka hōʻemi iki kūpono 'ana o ka'ōnaehana o hoʻokonukonu correlations (ʻOhana) ua lawe mai lohi coadaptation wahi. Ua paa ia wahi i loko o ka mea ana i wae maoli oi nui, harmonious hoahanau. He He maoli ae iaea ooieoeiiaeuiiai ka hoʻololiʻana i loko o ka evolutionary hou 'ana o kekahi o na kino o kekahi kanaka a me kekahi hui, e like me kekahi mau ola mea o ka biocenosis.

Like me, rudimentary hoʻohālike kanaka hale ke malama i paiiaʻi (i paiiaʻi). Kēia koena caecum, hookahi functioning kino e nui i loko o ka digestive'ōnaehana herbivores. Kona oihana i akaka nui iho la ia. High puluniu ai no kā lākou digestion pono i ka lōʻihi manawa, he makapo outgrowth ho i ka wahi, kahi a ke komo pū noho malaila microflora hele gradual kaʻina kanu digesting kelulose. Ma ke ala o ka evolution, hoomaka ae la ko kākou mau kūpuna eʻai emi momona, a nui ka ai, a alakai ai i ka gradual emi i loko o ka caecum. Ua huli i ke kumu, akā,ʻaʻole lapuwale. Kona kūlana i ka malama ana i ke kanaka'ōnaehana paleʻea'ōnaehana Ua nui nui iho la ia. I paiiaʻi na hoopaa mai ai i ka mea mua flora o ka AeXIeAaOIePEAaI, me he incubator o E. coli. People me ka appendectomy ma hope o infectious maʻi mea nui oi paʻakikī e hoʻi i ka maʻamau intestinal microflora. Ia mea ke kumu ka i paiiaʻi ua pinepine haawiia i like ke ano o ka aina no ka? Aneii o maikaʻi kēia microorganisms. Aia nā mea i 'ōlelo i ka wehe' ana o ka i paiiaʻi maoli i ka pilikia o ka hikoko o malignant ano.

Kumu o na holoholona

Ma nā mea ola ua hoi i ho'ākāka 'na luna aupuni o ka poe i lilo lākou hana i loko o nā kānāwai o ka mōʻaukala? Acaeoey o meaola, a e ma ke alanui i ka ia'na. Kēia, no ka laʻana, aia i loko o ka mānoanoa o ka iwi o ka abdominal nāʻiʻo i loko o pythons a me nā'ō koholā, a nō nā kumu o ka diawahine ia lala. Vestigial nā loko i na holoholona e noho ana ma ka pouli, maka nō. Au flightless manu Ua rudimentary'ēheu iwi. Ua nui kino i pau ka liu o kā lākou palapalaʻano, a me ka mea kanu. No laila, ma ka rhizomes o ka lilia o na awawa, palaoa mauu,'amaʻu i loaʻa unahi, a i na kumu o ka lau. Ka mokuna inflorescences Asteraceae ma lalo o ke kiʻiona aniani hiki ke hoopuni ike abortive stamens. Ma staminate pua kaʻukama koenaʻai, ua loaʻa i loko o ka waena konu o ka tubercle - like me ka mua. Mau mea a pau paa hoike o ka mōʻaukala? Acaeoey o ke aloha ao nei.

atavism

ʻepekema, ua kaʻawale kekahi hoikeana i loko o kekahi kūikawā hiʻona i ka poe nona i kā lākou mamao poʻe mākua, akā, noho e makou i ke kokoke laʻelaʻe 'ia. Na hoike ana i kapa atavism. Ka loa typical examples ona - he caudal appendage, fistula puʻu, he haʻi poo, i ke alo o nā hui o mammary glands, a me na mea e ae. Mau hoailona Ua ua nalowale i loko o ka papa o ka evolution, loaʻa like me ka ke nānā a koe.

It E e hoʻomaopopo i ke kumu o ka atavism a me ka - mea ole'ālike manaÿo. Kumu i keia manawa, i loko o nā kanaka o ka? Ueony, ka mea, kaʻana kekahi hiʻona. e loaʻa wale nō i loko o kekahi mau lala Atavism a me ka mai e lawe i kekahi kuleana pili i. I mai la lakou, incidentally, uaʻaʻole ia e hookahuli ai me developmental abnormalities, i he okoa maoli, e like me ka manamana o kona iwiʻaoʻao, mauae kapa, i ka kŰia o eono-io a me na mea e ae.

A pau i loaʻa i nā kumu a me ka atavism - he hoailona, e like me ka kekahi kahua o? acaeoey o ka evolutionary laau. A akaka maopopo o keia mea i na kino e i lilo nö ia no ka meaola hiki ke mālama 'ia no ka wā lōʻihi o ka manawa, ua emi progressively hina no ka nui a me ka hou aku ma muli o ke mutations.

I kēia kālaimeaola a me ka manawa o ka pulakaumaka o ke ao o ka genome o ke ola kanaka, a me kānaka. Ikepili ma ke kumu o rudimentary nā loko, e kōkua i ka hoʻoponopono 'ana i kekahi o ka ua e nīnau e pili ana i ka nā'ōewe i huli ma paha ua wahi i loko o ke ana a me ka ho'ēmiʻana o rudimentary nā loko.

"Vestigial nā loko" ma ka 'enehana

Ke manaʻo vestige figuratively me ke ola kŰia nalowale, a hoʻohana 'ia i loko o ke akamai. Like enehana E hana 'ia, aia no he maopopo analogy me liluwelo evolution. Aia Ua hoi pinepine i kapaʻia nā kumu o nā maomeka, machines, a me ka maalea, e hiki i ka liu o ko lakou ano ma ka keia kahua o ka? Acaeoey o kekahi 'oihana, akā, mau, e malama no ka hoʻokaulike me ka hae mua. Ano he kumu hoʻohālike kumu ma ka 'enehana kamepiula i mōkema, he floppy pā hōkū holo. Ma kaʻa 'enekinia, "vestigial hui," o ka mea hō'ā kaʻa laka, ma ka mokulele e like kumu hoʻohālike o ka' akomi kuhikuhi finder.
