Liluwelo regression o ka hana ana o kekahi mau mea kanu a me nā holoholona

Paleontology ua hoike ia na mea he nui o ka mea i hala? Ueo i ka nalowale loa.

Holomua a me setbacks ma ka aoao maoli - o ka manaʻo o ke ku pono ana. Ma ka hihia mua o ke ana a me ka hāʻawi 'ana i laha' ma ka Honua. Liluwelo regression mea he evolutionary neʻeʻana, wehewehe aku ma ka ka ho'ēmiʻana o ke kaianoho koholā, hoemiia ka helu ana o na kanaka ma muli o ke maladjustment. Kēia kaʻina ua pu ma ka emi i loko o ka nui o kekahi pae o? Ueo aie i ka puʻe ma luna o ia mau mea 'ē aʻe, e like me ka nalowale ana o? Ueo.

Liluwelo regression meaʻano nui manawa i ka lilo ana o ka hiki ana o meaola e ke hakuloli i ka hoʻololi 'ia.

Kēia neʻe He ano o parasitic meaola, manu, a me nā mea nō e noho ana i loko o na ana a me lola honua.

Liluwelo regression hiki ke manaoia he laʻana o parasites - flatworms. I ka mea nana e hoole kūpono 'ana kaʻina hana i Nohie ke ano nā loko, digestive nenoaiu, ko mākou hopohopo nenoaiu. I ka Ia manawa ua nui na ano manaʻo (slinging, omo na kiaha, etc.) pono e malama i ka poʻe koa i loko o ka gut. No ka laʻana, ka mea wahine crustaceans, e alakai i ka parasiticʻaoʻao o ke ola, loa hoʻi a pau na hoailona o arthropods, wale i ka hana o ka hua kau aua mai la. Parasitic i loko o ke kanaka kino, ua hiki ke paka bovine tapeworm ma kahi heʻumikumamākahi ieeeea? Hua paha, a hōʻoiaʻiʻo i ka hoomalu ana o ke kaua kino. No laila, i kēia mau mea noʻonoʻo i ka loa prolific ilo.

Liluwelo regression a me ka oukou mea kanu. E like me ka noho ana meaola, kā lākou aʻe kūpono 'ana ua pili loa aku i ka parasitism. No ka laʻana, malaila broomrape mea kanu. He parasitic ma ke kumu'ōnaehana o ka pua nānālā, clover, hemp. Broomrape ua pōwehiwehi kumu, a me kona mea kaupaona-e like lau mai i apo ia chlorophyll. Ka mea, i hoʻolauna i loko o ke kumu o kekahi mea kanu me ke kōkua o ke omo na kiaha, a omo mai i ka māhuaola ke kino kaua.

Animal ka hoopakele ana i stillness ma ke ola, kino ana o loa i ka larval ke kahua. Chord o ko lākou ho'ēmi i kā. Mau meaola, ma ka nui, pili Pogonophora - 'elele o kekahi mauʻano o ka brahiata. Mau kanaka mai,ʻaʻole anei e like me na holoholona. Ka mea noho ma luna o ka seabed, a nō ola. Pogonophora i ka naau, a me ka lolo, nae,'ōpū, a ua hoemi i kona waha. Nā tentacles i naehana nā loko. Loko, ka mea i lōʻihi hina, i hoʻolako pono i na moku ke koko. Ka mea, i nā loaa microorganisms. ka mea, (microorganisms) i ka wā nui Pogonophora pulls i ka heluia na lauoho o loko. Ma lalo o ka aoao o kūikawā nā'ūhū, e hōʻuluʻulu manaʻo microorganisms a ke kemu i loko o ka na ka ulu o ke. Ke alo aku o ka embryonic intestinal proves ke ola ana o keia kino i loko o nā kūpuna pogonophores. Akā, ma muli o ia i ka mea ana i ke kaʻina hana o ka digestion i wahi mawaho o ke kino, i hoemiia gastrointestinal nā loko.

Regression o na holoholona e noho ana lola honua paha iloko o na ana, ke i ke kumu hoohalike o Proteus hiki ke noʻonoʻo. 'O kēia' elele o ka papa o amphibians, e like me ka newt. He holoholona noho ana ma loko o nā lua. Ma ke poo ma na aoao elua ka mea, he mawaho halo o mua. Proteus ke hanu, a me ka wai, a ma luna o ka'āina. Ma ka hihia mua e hoʻohana i ka halo o mua, a me ka lua - malamalama. No ka Proteus ola ma ka hohonu ana, oia ka mea, he serpentine shape. Kona kino ka aniani moakaka, colorless,ʻaʻohe pigment. Ma nā mākua, i ka poeikohoia o na nā loko o ka hihio uhi ma ka ili, ka larvae i rudimentary mau maka. Ua i ma luna o ke kino a me nā hui o Proteus underdeveloped lala.

E like me ka aaiaoe muli o evolutionary loli alakai i ka simplification o kaʻaha hui 'ilikai, ke mutation hana.

Ma ka hooulu ana o ka ke aloha honua kahiāuli ekolu mau mea. Aromorphosis characterizes ka mea ulu i loko o ka nui o ka hui ana o meaola. Idioadaptation mea i ka hoʻololiʻana i ka papa me kekahi loli kumu kahua o loko o ka liluwelo 'ole. Ka nohona ma degeneration mea he simplification o ka nui o ka hui o ke ola kanaka.
