AMSTERDAM, NL, Epulo 3, 2012 - Zaka zoposa 65 miliyoni zapitazo, meteor inagunda m'nyanja pafupi ndi gombe lomwe tsopano limatchedwa Yucatan Peninsula ku Mexico. Tikudziwa za chochitikachi chifukwa kugundako kudapangitsa kuphulika kwamphamvu komwe kunapangitsa kuti dziko lonse lapansi likhale la iridium.

Kutsatira kugundana kunabwera kutha komwe ma dinosaur onse (kupatula mbalame) adasowa. M'nyanja, ma amoni ochulukira adafa, monganso adani ambiri olusa monga ma plesiosaurs akuluakulu. Pafupifupi 80 mpaka 90 peresenti ya zamoyo za m’nyanja zikhoza kukhala zatha.

Koma ngati dziko la pambuyo pa kugunda linali dziko la imfa - linalinso dziko la mwayi.

Zaka mamiliyoni ochepa okha pambuyo pake, pansi pa nyanja yakuya yomwe tsopano ili tawuni ya Faxe, Denmark (inali nthawi yotentha kwambiri padziko lapansi ndi mafunde a m'nyanja anali okwera kwambiri), ma corals odabwitsa kwambiri adakhazikitsa maziko. Anayamba kumanga zitunda zomwe zimakulirakulirakulira ndikukula pakadutsa zaka chikwi chilichonse, ndipo pamapeto pake zidakhala, monga momwe timaganizira masiku ano, nyumba zabwino kwambiri zomwe zimalandirira zamoyo zamitundumitundu.

Machulu anakhala malo osonkhanitsira. Makorali ena anagwirizana ndi dongosololi, limodzi ndi mitundu ina yambiri ya zamoyo za m’madzi. Dendrophylia candelabrum inakhala yabwino kwambiri ngati chimango cha zomangamanga. Pamene dziko lapansi linayamba kuzizira kachiwiri ndipo madzi a m'nyanja anatsika ndipo nyumba za coral izi, Cenozoic Co-Op Cities zoyambirirazi, zidasiyidwa pamwamba komanso zowuma, mitundu yopitilira 500 yam'madzi idakhazikitsidwa pano.

Flash-forward ku 21st Century yathu. Kukumba miyala kwa nthawi yayitali kwapanga "dzenje lalikulu kwambiri ku Denmark," malinga ndi wofufuza waku Danish Bodil Wesenberg Lauridsen wa payunivesite ya Copenhagen, yemwe adalankhula ndi gulu la ofufuza amadzi ozizira omwe adasonkhana ku Amsterdam sabata ino.

Asayansi atayamba kuphunzira za “dzenje” limeneli ndi zinthu zina zapafupi, anazindikira kuti mapiri akale a matanthwewa, omwe anakhalapo zaka 63 miliyoni zapitazo, ndi akale kwambiri odziwika ndipo akhoza kukhala chizindikiro choyamba cha mlengalenga wa chilengedwe chatsopano.

Pa zamoyo zomwe asayansi apeza m’nyumba zakalekale za “nyumba” mpaka pano, zambiri sizikudziwikabe.

Komanso, wasayansi waku Danish adauza omvera ake, zokwiriridwa zakale zambiri zikadali m'machulukidwe, zikuyembekezera kupezeka. M'madera ena, kusungidwa kwa zitunda sikunakhale kwabwino, koma zigawo zina za miluzi zimapereka malo ophunzirira bwino kwambiri.

Kodi pali akatswiri odziwa zakale zam'madzi omwe akufuna projekiti?
