Ngā Tauira Pātai e Matapaki ana i te Ariā Whanaketanga i Muri i a Darwin
Ko te whanaketanga he ariā taketake i roto i te koiora e whakamārama ana i te āhua o te hurihanga o ngā rauropi i roto i te wā mā te kōwhiringa taiao me ētahi atu tikanga. Whai muri i te whakaurunga mai o te ariā o te whanaketanga mā te kōwhiringa taiao e Charles Darwin i te rautau 19, he maha ngā kaipūtaiao i haere tonu ki te rangahau hei whakawhānui me te whakahou i te ariā. Ko te ariā whanaketanga muri-Darwinian e kapi ana i ngā whakaaro hou e whakamārama ana i ngā āhuatanga kāore i taea e te ariā taketake a Darwin. Ka tūhuratia e tēnei tuhinga ētahi tauira raruraru me ngā kōrero e pā ana ki te ariā whanaketanga muri-Darwinian, e whakarato ana i te māramatanga hohonu ake mō ēnei ariā.
Te Mārama ki te Ariā Whanaketanga i Muri i te Wā o Darwin
I mua i te ruku hohonu ki ngā pātai tauira, me matapaki tātou he aha te ariā whanaketanga muri i te wā o Darwin. Ko te whanaketanga muri i te wā o Darwin e kapi ana i ngā ariā i whakawhanakehia i muri i a Darwin, pērā i te ira taupori, te ariā whakahiato hou, te rere o te ira, te whakarerekētanga ira, me te tūranga o te epigenetics i roto i te whanaketanga. Ko te whakahiato hou, ko te Hanganga Whakawhanake Hou rānei, he whakaurunga o te koiora taketake me ngā mātāpono o ngā ira Darwin me Mendelian i puta mai i te tīmatanga o te rautau 20.
Anei ētahi o ngā ariā matua o te whanaketanga i muri i te wā o Darwin:
1. Te Ira Tangata o te Taupori: Ko te ako i te tohatoha me ngā huringa o ngā auau ira i roto i ngā taupori e kiia ana ko te tūāpapa o te koiora whanaketanga o ēnei rā.
2. Ngā Ira Whakarerekētanga Ira: Ko ngā ira whakarerekētanga he huringa i roto i ngā raupapa DNA ka taea te whakaputa i ngā rerekētanga ira. Ko tēnei rerekētanga te rauemi matua mō te kōwhiringa taiao.
3. Rere Ira: Te whakawhiti i ngā ira, i ngā ārel rānei, mai i tētahi taupori ki tētahi atu mā te hekenga takitahi, mā te marara rānei o ngā gamete.
4. Te Hurihuri Ira: Ngā huringa matapōkere o ngā auau ira mai i tētahi whakatipuranga ki tētahi whakatipuranga, ka hua ake ai he huringa whanaketanga.
5. Epigenetics: Te ako i ngā panonitanga o te whakaaturanga ira kāore e uru ki ngā panonitanga o te raupapa DNA tonu, ā, ka taea te tuku iho.
Ngā Pātai Tauira me te Kōrero
Anei ētahi tauira o ngā pātai e pā ana ki te ariā whanaketanga i muri i te wā o Darwin me ā rātou matapakinga:
Pātai 1: Ngā Ira Whakarerekētanga me ngā Rerekētanga Ira
Pātai: Whakamāramahia te pānga o ngā whakarerekētanga ira ki te rerekētanga ira i roto i te taupori, me pēhea hoki tēnei e whai wāhi ai ki te whanaketanga. Homai he tauira tuturu.
Kōrero:
He pūtake nui ngā whakarerekētanga ira i roto i ngā taupori. Ka puta noa mai ēnei i te kore whakaaro, i te hua rānei o ngā āhuatanga o waho pērā i te irahiko, i ngā matū rānei. Ahakoa he koretake, he kino rānei te nuinga o ngā whakarerekētanga ira, ka taea e ētahi te whakarato i tētahi painga whiriwhiri ki ngā tāngata takitahi i raro i ētahi āhuatanga taiao.
Hei tauira, ko ngā whakarerekētanga ira e ārai ana i ngā huakita ki ngā paturopi he tauira o te whai wāhi a ngā whakarerekētanga ira ki te whanaketanga. Ina pāngia ngā huakita e ngā paturopi, ko ngā mea anake he ātete ngā whakarerekētanga ira ka ora me te whakaputa uri. I roto i te wā, ka noho te taupori huakita hei mea nui mā ngā tāngata e mau ana i ēnei whakarerekētanga ira, he tukanga e mōhiotia ana ko te kōwhiringa taiao.
Pātai 2: Te Hurihanga Ira
Pātai: He aha te nekehanga ira, ā, he aha te rerekētanga o tēnei tukanga mai i te kōwhiringa taiao? Homai he tauira o te pānga o te nekehanga ira ki ngā auau ira i roto i tētahi taupori iti.
Kōrero:
Ko te nekehanga ira ko te huringa matapōkere o ngā auau ira mai i tētahi whakatipuranga ki tētahi whakatipuranga, he mea nui ake i roto i ngā taupori iti. Kāore i rite ki te kōwhiringa taiao, he mea whakatau, ā, e aro ana ki te 'oranga o te mea tino pai,' ko te nekehanga ira he tukanga tūpono ka taea te whakanui ake i te maha o ngā ira, te ngaro rawa atu rānei i roto i tētahi taupori mā te tūpono noa iho.
Hei tauira, ko te pānga aukati ira, arā, ka tino heke te rahi o te taupori nā te mea he tino kino te taiao. I te whakaoranga o te taupori, ko te toenga o te kanorau ira ka ahu mai pea i te tauira matapōkere o ngā ira e kitea ana i te wā o te aukati, kaua i te mea nā tetahi painga urutau motuhake.
Pātai 3: Epigenetics me te Whanaketanga
Pātai: Matapakihia te tūranga o te epigenetics i roto i te whanaketanga, me te homai i ngā tauira o te pānga o ngā whakarerekētanga epigenetics ki tētahi taupori.
Kōrero:
Ko te epigenetics e pā ana ki ngā huringa o te whakaaturanga ira kāore e uru ki ngā huringa o te raupapa DNA engari he mea tuku iho. Kei roto i te kupu he maha ngā tikanga, tae atu ki te methylation DNA me ngā whakarerekētanga histone, ka taea te whakahohe, te whakakore rānei i ngā ira me te kore e whakarerekē i te raupapa DNA tonu.
Ko tētahi tauira o te epigenetics i roto i te whanaketanga ko te urupare a te rauropi ki te kai, ki te ahotea taiao rānei, ka taea te awe i te whakaaturanga ira whakawhiti-whakatupuranga. Hei tauira, i roto i ētahi tipu, ka taea e te ahotea mai i te huarere tino kino te whakaoho i ngā whakarerekētanga epigenetics e whakanui ana i te manawanui ki ngā āhuatanga kino i roto i ngā whakatipuranga o muri mai. E whakaatu ana tēnei me pēhea te pānga o ngā huringa taiao i roto i te whakaaturanga ira ki te whanaketanga mō te wā roa.
Whakamutunga
Kua tino whanake haere tō tātou māramatanga ki te ariā whanaketanga mai i te wā o Tāwini. Mā te whakahiatotanga hou, te ira taupori, me te epigenetics, ka whiwhi tātou i tētahi pikitia whānui ake mō te mahi a te whanaketanga i ngā taumata ngota, taupori, me te taiao. Mā te whakautu me te ako i ngā tauira, ka taea e tātou te kite i te hononga o ēnei whakaaro ki te hanga i te koiora whanaketanga hou, te whakamārama i te kanorau o te ora i runga i te Ao, me te whakarato i ngā māramatanga ki ngā tikanga urutau me te huringa momo i roto i te wā.
Mā te ako i te whanaketanga i muri i te wā o Darwin ka homai he taputapu ki a tātou hei matapae i te urupare a ngā rauropi ki ngā huringa taiao a meake nei, he mea nui tēnei mō te aro atu ki ngā wero o te ao pēnei i te huringa āhuarangi me te tiaki i te kanorau koiora.
