Poona malo aakulu komanso abwinja a ku Antarctica, asayansi nthawi zambiri amakopeka ndi kukongola kwake, nyengo yoipa, ndi zochitika zodabwitsa. Komabe, kafukufuku wambiri wasayansi avumbulutsa zinthu zochititsa chidwi kwambiri zomwe zingasinthe kaonedwe kathu ka kontinentiyi.
Antarctica imadziŵika chifukwa cha mikhalidwe yake yoipitsitsa, pamwamba ndi pansi pa kuya kwake kozizira. Ngakhale kuti zachilengedwe za m'derali zasintha kuti zikhale ndi moyo m'mikhalidwe yovutayi, zikuwoneka kuti pakhoza kukhala zambiri zomwe zimabisala pansi pa madzi oundana - zolengedwa zazikulu komanso zoopsa.
Ofufuza akhala akuwunika kwa nthawi yayitali lingaliro la polar gigantism kapena abyssal (deep-sea) gigantism, zomwe zikusonyeza kuti nyama zomwe zili m'madera ozizira a m'nyanja zimakhala zazikulu kuposa anzawo kumadera ena a dziko lapansi. Chodabwitsachi chawonedwa m'mitundu yosiyanasiyana ya m'madzi, monga sikwidi, jellyfish, ndi ma isopod a m'nyanja yakuya. Zamoyozi, zomwe zimakhala zochititsa chidwi kale kukula kwake, zimachuluka kwambiri m'nyanja ya Antarctic.
Koma kodi ku Antarctica kuli zamoyo zazikuluzikulu za m'nyanja n'kupitirira kungoyerekeza? Kodi pangakhale zilombo zenizeni zobisalira pansi? Posachedwapa mawu osadziwika, monga Julia ndi Bloop, awonjezera mpweya wa mystique ku lingaliro.
Phokoso la Julia, lolembedwa mu 1999, lidachokera ku Antarctic Peninsula ndi akatswiri odabwitsidwa, omwe sanathe kudziwa komwe adachokera. Kudodometsedwa kofananako kudazungulira phokoso losamvetsetseka la Bloop, lojambulidwa mu 1997 kugombe lakumwera chakumadzulo kwa South America. Akatswiri ena a zachiwembu amanena kuti kumveka kosadziwika bwino kumeneku kungakhale kogwirizana ndi kukhalapo kwa zimphona zazikulu zomwe zimakhala m’nyanja ya Antarctic.
Ngakhale kuti lingaliro la zolengedwa zoopsazi lingawonekere ngati nthano yasayansi, silosamveka. Kukula ndi kusafikirika kwa nyanja ya Antarctic kwapangitsa kuti asayansi asamavutike kufufuza mozama zakuya kwake. Ndizomveka kuti zamoyo zina, zomwe zimatha kupeŵa kuzindikiridwa, zasintha m'madzi akutaliwa.
Komanso, lingaliro la polar gigantism limadzutsa kuthekera kwina kochititsa chidwi. Ngati zamoyo zazikuluzikuluzi ziliko kale, kodi kufalikira kwa mlengalenga kungathe kukulitsa kukula ndi mphamvu zawo? Izi zikubweretsa funso loti tangoyang'ana kumene ku Antarctica komwe kumakhala doko.
Komabe, okayikira amatsutsa kuti polar gigantism phenomenon imakhudza kwambiri zamoyo zopanda msana ndipo sizingatheke kufalikira ku zolengedwa zazikulu zam'madzi. Iwo amati kuzizira koopsa komanso zakudya zochepa zomwe zili ku Antarctica sizingagwirizane ndi zofunikira zamphamvu za nyama zazikulu.
Ngakhale anthu amakayikira, kupezeka kwa zolengedwa zoopsa kwambiri ku Antarctica kuli ndi chidwi chokopa chidwi. Ndikofunikira kuyandikira zongopekazi mosamalitsa zasayansi, chifukwa malingaliro amatha kuthamangitsidwa nthawi zambiri ndi zochitika zosadziwika. Kufufuza mozama, kufufuza, ndi kupita patsogolo kwaukadaulo ndikofunikira kuti tidziwe zowonadi zonena zotere.
Tikamapitiriza kuvumbula zinsinsi za ku Antarctica, chiyembekezo cha zolengedwa zazikulu kwambiri zobisala pansi pa madzi ozizira kwambiri chimakhala chosangalatsa kwambiri. Lingaliro la gigantism la polar limatsutsa kumvetsetsa kwathu kwa chilengedwe ndipo limatikakamiza kulimbana ndi lingaliro lakuti pangakhale zambiri zoti tidziŵe mkati mwa dziko lathu lapansi. Ndi nthawi yokhayo, kafukufuku, ndi ofufuza olimba mtima omwe angawulule chowonadi kumbuyo kwa zilombo zodabwitsa za ku Antarctica.
