I ke kūlohelohe hiki iā mākou ke nānā i kekahi nā hoʻolālā hoʻohua, aʻo kekahi o lākou he oviparity. E ʻike ʻoe he nui nā holoholona e ukali i ka hoʻolālā like, i ʻike mua ʻia i ka mōʻaukala evolutionology ma mua o nā livebearers.
inā makemake ʻoe e ʻike he aha nā holoholona oviparous, he aha kēia hoʻolālā hoʻohua a me kekahi mau laʻana o nā holoholona oviparous, e hoʻomau i ka heluhelu ʻana i kēia ʻatikala na PeritoAnimal. E hoʻonā ʻoe i kāu mau kānalua āpau a aʻo i nā mea kupaianaha!
he aha nā holoholona oviparous
ʻO ʻoe holoholona holoʻokoʻa oviparous ʻo ia kēlā e waiho i nā hua i pā, ʻoiai lākou i waho o ke kino o ka makuahine. Hiki i ka hoʻoulu ke kūwaho a i ʻole i loko, akā hatching mau i kahi o waho, ʻaʻole i ka ʻōpū o ka makuahine.
ʻO ʻoe iʻa, amphibians, nā mea kolo a me nā manu, e like me kekahi mau māmala i kekahi manawa, he oviparous lākou. Hoʻokomo pinepine lākou i kā lākou mau hua i nā pūnana i pale maikaʻi ʻia, kahi e ulu ai ka embryo i loko o ka hua manu a laila hiki ke kō. kekahi holoholona he ovoviviparous, ʻo ia hoʻi, hoʻokomo lākou i nā hua i loko o ke kino ma kahi o kahi pūnana a hānau hānau ʻia nā keiki keiki mai ke kino o ka makuahine. ʻIke ʻia kēia i kekahi ʻano manō a me nā moʻo.
KA hānau holoholona oviparous he hoʻolālā evolution. hiki ke hana hoʻokahi a i ʻole nā hua. ʻO kēlā me kēia hua manu he gamete i hana ʻia e nā mea kūmole mai ka wahine (hua manu) a me nā mea kūmole mai ke kāne (sperm). Pono ka sperm e ʻike i ko lākou ala i ka hua manu, i loko o kahi kūloko (ke kino o ka wahine), ke kūloko ka fertilization, a i ʻole ma kahi kūwaho (e laʻa me ka wai wai), ke kūwaho ka mea kanu.
I ka manawa e hui ai ka hua a me ka sperm, ʻōlelo mākou ua hoʻomomona ʻia ka hua a lilo ia i embryo e hoʻomohala i loko o ka hua manu. Hana nā holoholona he nui i nā hua he nui, akā nāwaliwali loa, a ʻo ka pōmaikaʻi o kēia hoʻolālā ʻo ia, ma ka hana ʻana i nā keiki he nui, aia kahi manawa kūpono e ʻoi aku i kahi o lākou ke ola i nā mea ʻaihue. Hoʻokumu nā holoholona ʻē aʻe i mau hua liʻiliʻi, akā nui a ikaika hoʻi a hoʻonui kēia i ka hiki i ka hopena o ke kanaka hou i ka hopena a hatch, e hoʻoulu ana i kahi kanaka ikaika hou, kahi e loaʻa ai nā mea hou aku e pakele i nā mea ʻaihue ke hānau.
ʻOiai he oviparous kekahi kāna drawbacks. ʻAʻole like me nā holoholona viviparous a me ovoviviparous, lawe i kā lākou keiki i loko o ko lākou kino, nā holoholona oviparous pono e pale a hūnā paha i kā lākou mau hua i kona wā hoʻomohala ma nā hanana i kapa ʻia nā pūnana. Noho pinepine nā manu ma luna o kā lākou mau hua e hoʻomehana iā lākou. I ka hihia o nā holoholona i pale ʻole i kā lākou pūnana, loaʻa mau ka mea hiki ke loaʻa iā lākou a ʻai iā lākou, no laila he mea nui e koho pololei i ka pūnaewele pūnana a hūnā pono i nā hua.
ʻO nā holoholona ʻo Oviparous a me Viviparous - Nā ʻokoʻa
KA ʻokoʻa nui ma waena o nā holoholona oviparous a me nā holoholona viviparous ʻaʻole ulu nā holoholona oviparous i loko o ka makuahine, ʻoiai nā holoholona viviparous e hoʻololi i nā ʻano hoʻololi āpau i loko o ko lākou makuahine. No laila, hoʻomoe nā holoholona oviparous i nā hua e hoʻomohala a hatch i nā ʻōpio. ʻOiai hānau ʻia nā holoholona viviparous ma ke ʻano he ʻōpio ola a ʻaʻole waiho hua.
ʻO nā manu, nā mea kolo, nā amphibians, ka nui o nā iʻa, nā pepelu, molluscs, arachnids a me nā monotremes (nā māmela me nā ʻano reptilian) he mau holoholona oviparous. ʻO ka hapa nui o nā māmela he mau mea ola. No ka hōʻalo i ke kanalua, hōʻike mākou i papa inoa hiʻohiʻona hoʻokaʻawale i ka oviparous mai nā holoholona viviparous:
ʻO Oviparous:
- Hoʻopuka nā holoholona Oviparous i nā hua i oʻo a pao hoʻi ma hope o ke kipaku ʻia ʻana mai ke kino makuahine;
- Hiki ke hoʻomoe i nā hua manu a i ʻole unfertilized paha;
- Hiki i ka hoʻouluulu i loko a i waho paha;
- Hana ʻia ka ulu ʻana o Embryo ma waho o ka wahine;
- Loaʻa i ka embryo nā meaola mai ka hua manu;
- ʻO lalo ka likelika o ke ola.
ʻO Viviparous:
- Hānau nā holoholona Viviparous i nā ʻōpio ola piha i hoʻomohala ʻia;
- ʻAʻole lākou e hoʻomoe i nā hua manu;
- ʻO ka momona o ka hua manu i loko mau;
- Hana ʻia ka ulu ʻana o Embryo ma waena o ka makuahine;
- ʻOi aku ka nui o ka hiki ke ola.
Nā laʻana o nā holoholona oviparous
Nui a hewahewa nā ʻano holoholona e waiho hua ana, ma lalo kekahi o lākou:
- manu: kau wale kekahi mau manu hoʻokahi a ʻelua paha hua manu momona, ʻoiai nā mea e waiho i nā mea he nui. ʻO ka maʻamau, ʻo nā manu e hoʻomoe i hoʻokahi a ʻelua paha mau hua manu, e like me nā manu kōkō. ʻaʻole lākou e ola lōʻihi i ke kūlohelohe. Hoʻolālā nui kēia mau manu i ka mālama ʻana i kā lākou ʻōpio e kōkua iā lākou e ola. Ma ka lima ʻē aʻe, nā manu kēlā kau nui i nā hua, e like me nā koloka maʻamau, ʻoi aku ka nui o ko lākou ola, a ʻaʻole pono lākou e hoʻolilo i ka manawa me kā lākou keiki.
- Amphibians a me nā mea kolo: nā rana, nā newts a me nā salamanders he amphibians āpau, noho lākou i loko a ma waho o ka wai, akā pono lākou e noho mākū, a e hoʻomoe hoʻi i kā lākou mau hua, ʻoiai ʻaʻohe pūpū o kēia mau hua manu a i ka lewa, maloʻo koke lākou. ʻO nā kolo, e like me nā moʻo, nā crocodile, nā moʻo, nā kuhukukū a me nā moʻo, hiki ke noho ma ka ʻāina a i ʻole ka wai, a hoʻomoe lākou i nā hua i waho a i ʻole i loko o ia mea, kaukaʻi ʻia i nā ʻano. ʻOiai ʻaʻole maʻa lākou i ka mālama ʻana i kā lākou pūnana, waiho lākou i nā hua he nui i hoʻonui ka nui o ke ola.
- Iʻa: nā iʻa āpau kau lākou i kā lākou mau hua i ka wai. Kipaku aku nā iʻa wahine i kā lākou mau hua i waenakonu, waiho iā lākou i nā mea kanu wai a hoʻolei paha iā lākou i loko o kahi lua i ʻeli ʻia. Hoʻokuʻu ka iʻa kāne i ka sperm ma luna o nā hua. Mālama kekahi mau iʻa, e like me cichlids, i kā lākou mau hua i loko o ko lākou waha ma hope o ka momona e pale aku iā lākou mai nā mea ʻino.
- nā ʻalopaka: ka hapa nui o nā arachnids, myriapods, hexapods a me nā crustaceans e hana i ka hui arthropod he oviparous. Nā punawelewele, centipedes, pāpaʻi a me nā pulelehua kekahi o nā miliona o nā arthropods e waiho hua ana, a kau lākou i mau haneli o lākou. ʻO kekahi e waiho i nā hua i hoʻoulu ʻia ma o ka hoʻoulu ʻana i loko, a ʻo kekahi e hoʻomoe i nā hua hua ʻole e pono ai ka sperm.
Nā laʻana o Oviparous Mammals
Kākaʻikahi loa ka waiho ʻana o nā hua moa i nā māmela. ʻO kahi hui liʻiliʻi i kapa ʻia ʻo monotremate. Hoʻopili kēia pūʻulu i ka platypus a me echidnas. Hiki iā mākou ke loaʻa iā lākou ma Australia wale nō a ma kekahi mau wahi o ʻApelika. Ke waiho nei kēia mau mea i mau hua, akā ʻaʻole like me ke koena o nā holoholona oviparous, hānai nā monotremes i kā lākou keiki me ka waiū a he lauoho kekahi.
