Pono nā mea ola āpau e hana hou i hoʻomau i ka laha. ʻOiai kēia, ʻaʻole kūleʻa a ʻaʻole pono paha nā kānaka āpau o kahi ʻano kope. ʻO kahi laʻana, hāʻawi ʻia nā holoholona e noho ana i nā eusocieties i kahi kuleana i loko o ka hui a hoʻokahi a i ʻole kekahi mau mea e kope. ʻO nā holoholona lone, e ʻimi a hakakā no kā lākou kuleana e hoʻohua hou a hoʻomau i kā lākou genes ponoʻī.
Hana kekahi hui nui o nā holoholona i kahi hoʻolālā hānau hou, kahi e pono ʻole ai ka loaʻa ʻana o ka wahine ʻē aʻe e hānau hou. E kamaʻilio mākou e pili ana iā lākou āpau i kēia ʻatikala PeritoAnimal. Makemake e ʻike hou aʻe e pili ana hoʻoulu holoholona? E hoʻomau i ka heluhelu!
He aha ka hanauna holoholona?
ʻO ka hana hou ʻana i nā holoholona kahi hana paʻakikī o nā loli hormonal i kumu i nā loli i ke kino a me ka lawena i kēlā me kēia mea e loaʻa kahi kumu hoʻokahi: e hana i nā keiki.
No kēia, ʻo ka hoʻololi mua e pono ai moekolohe ʻaʻano o na holoholona. Kū kēia mea i kekahi manawa i ke ola o kēlā me kēia kanaka, kaukaʻi ʻia i kā lākou laha. Hoʻomaka ia me ka hoʻokumu ʻana o nā mea moekolohe a me ka hoʻokumu ʻia ʻana o nā gametes, i kapa ʻia ʻo spermatogenesis i nā kāne a me nā oogenesis i nā wahine. Ma hope o kēia māhele, ua nānā ʻia kahi ʻāpana o nā ola o nā holoholona e ʻimi no kahi hoa e hoʻokumu i kahi paʻa e alakaʻi iā lākou e hana hou.
Eia nō naʻe, aia kekahi mau holoholona, ʻoiai ke loaʻa ʻana o kēia mau meaola, i kekahi mau manawa a ma lalo o nā kūlana kikoʻī, mai hoʻohana iā lākou. ʻIke ʻia kēia ma hoʻoulu hānau ʻole i nā holoholona.
Nā ʻano hanauna holoholona
I ke kūlohelohe aia kekahi mau ʻano o ka hana hou i nā holoholona. He ʻano kūlike ko kēlā me kēia o lākou e ʻokoʻa ai kekahi i kekahi. Ma nā ʻōlelo laulā, hiki iā mākou ke ʻōlelo i ka ʻano hanauna holoholona he:
- Hana kolohe i nā holoholona
- Hana kope ʻaihue i nā holoholona
- Hoʻohuli hoʻololi i nā holoholona
Ma hope, e kamaʻilio mākou a hāʻawi i nā laʻana o kēlā me kēia o lākou.
Hana kolohe i nā holoholona
Hoʻohālikelike ʻia ka hana kolohe ʻana i nā holoholona i ka pili ʻana o ʻelua mau kānaka. hoʻokahi wahine a hoʻokahi kāne. E hua mai ka wahine i nā hua i hana ʻia e ka oogenesis i loko o kāna mau ovaries. ʻO ke kāne hoʻi, e hana i ka sperm i loko o kāna mau testicle, kahi e maʻa mau ʻia e ka liʻiliʻi a me ka neʻe kiʻekiʻe. Loaʻa kēia mau sperm i ka hana o ka hoʻomomona ʻana i ka hua a hana i kahi zygote e hoʻololi lohi e hana i kahi kanaka piha.
Hiki i ka momona ke hana ma loko a ma waho paha o ke kino o ka wahine, i ʻike ʻia ma ke ʻano he kūloko a i ʻole kūwaho, e pili ana i nā ʻano.
ʻO ka fertilization kūloko i nā holoholona
I ka wā o ka momona, hele ka sperm ma loko o ka ʻōnaehana hānau wahine e ʻimi ai i ka hua. Hiki i ka wahine ke hoʻomohala i nā keiki i loko ona, e like me nā holoholona hānau, a i waho paha. Inā kū ka ulu ʻana o ka embryonic ma waho o ke kino wahine, ke kamaʻilio nei mākou e pili ana i nā holoholona oviparous, e hoʻomoe ana i nā hua manu.
Hoʻomomona kūwaho i nā holoholona
ʻO ka mea ʻē aʻe, nā holoholona me ka hoʻohua waho hoʻokuʻu i kā lākou gametes i ke kaiapuni (maʻa mau i ka wai), nā hua ʻelua a me ka sperm, a mālama ʻia ka momona ma waho o ke kino.
ʻO ka hiʻohiʻona nui loa o kēia ʻano hana kope ke lawe nā mea i loaʻa i kā lākou genome nā mea kūmole mai nā mākua ʻelua. No laila, hoʻonui ka hana kolohe ʻana i ka hiki ke ola o kahi ʻano i ka wā lōʻihi, mahalo i ka loli a ke ʻano e hana ai.
Hana kope ʻaihue i nā holoholona
Hoʻohālikelike ʻia ka hana hou ʻana o ka moekolohe i nā holoholona e ka loaʻa ʻole o kekahi kanaka o ka wahine ʻē aʻe. No laila, like ka pua me ka mea hānau.
Eia kekahi, ʻaʻohe pili o ka hana hou asexual i nā hunaola germ, ʻo ia hoʻi, nā hua a me ka sperm; i ka hapanui o nā hihia, aia lākou nā ʻāpana somatic hiki ke hoʻokaʻawale. ʻO nā huna Somatic nā hunaola maʻamau i ke kino.
Nā ʻano o ka hana hou ʻana o ka moekolohe i nā holoholona
A laila, e ʻike mākou he nui nā ʻano o ka hana kolohe ʻole i nā holoholona:
- gemmulation a i ʻole gemmation: ʻo ia ka hana kope asexual maʻamau o nā ʻanuʻu moana. Hoʻopili kahi ʻano kikoʻī o nā hunaola i nā mea ʻai a, i ka hopena, hoʻokaʻawale a hana i kahi ʻāpana e hāpai i kahi kanaka hou ...
- ʻōpuʻu: I nā hydras, kahi ʻano kikoʻī o ka cnidarian, hana kolohe ʻia e ka ʻōpuʻu. Ma ka ʻili o ka holoholona, hoʻomaka kekahi hui o nā hunaola e ulu, e hana ana i kahi kanaka hou i hiki ke hoʻokaʻawale a noho kokoke paha i ke kumu.
- ʻāpana māhele: kekahi o nā ʻano hana kope e hana ʻia e nā holoholona e like me ka starfish a i ʻole planarians. Hiki ke hoʻokaʻawale ʻia kou kino i nā ʻāpana he nui, i kēlā me kēia e hāpai i kahi kanaka hou.
- Parthenogenesis: i kēia ʻano hana kope asexual, pili ka cell germ, ʻo ia ka hua. ʻO kēia, ʻoiai inā ʻaʻole momona, hiki ke hoʻomohala a hana i hoʻokahi wahine e like me ka makuahine.
- ʻO Gynogenesis: He hihia kakaikahi kēia o ka hana kope asexual, kahi wale nō i kekahi amphibians a me nā iʻa bony. Hāʻawi ke kāne i kāna sperm, akā hoʻohana wale ʻia kēia i mea hoʻonāukiuki no ka ulu ʻana o ka hua manu; ʻaʻole hāʻawi ʻoiaʻiʻo i kāna kumuwaiwai.
Nā holoholona me ka hoʻouluulu asexual
ʻO kekahi o nā holoholona me ka hana hou asexual hiki iā mākou ke loaʻa ʻo kēia aʻe:
- ʻO Hydra
- Nā ʻūlū
- Starfish
- anemone kai
- ʻino kai
- kukama kai
- ʻenepe kai
- amoebas
- nā salamanders
Hoʻohuli hānau ʻē aʻe i nā holoholona
Ma waena o nā holoholona, ʻoiai ʻaʻole maʻa mau, hiki iā mākou ke ʻike i ka hoʻohua hou. I loko o kēia hoʻolālā hoʻohua, ka hoʻopili ʻia ka hānau kolohe a me ka moe kolohe, ʻaʻole naʻe pono.
ʻO kēia ʻano hana kope pinepine ʻia i ka honua kanu. I nā holoholona laha ʻole ia, akā hiki ke ʻike ʻia i kekahi mau eusocieties, e like me nā naonao a me nā pi, ʻo ia hoʻi, i nā holoholona invertebrate. ʻO ka papa hana hoʻoulu holoholona i nā holoholona e hilinaʻi ʻia i kēlā me kēia laha.
Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Hoʻohua holoholona, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
