Akatswiri ofukula zinthu zakale ndi ophunzira ochokera ku Hakai Institute ku yunivesite ya Victoria ku British Columbia, komanso a First Nations akumaloko, apeza mabwinja a tawuni yomwe isanachitike mapiramidi aku Egypt ku Giza.
Malo omwe ali pachilumba cha Triquet, makilomita pafupifupi 300 kuchokera ku Victoria kumadzulo kwa British Columbia, apanga zinthu zakale zomwe zidapangidwa zaka 14,000 zapitazo, zaka pafupifupi 9,000 kuposa mapiramidi, malinga ndi Alisha Gauvreau, wophunzira pa yunivesite ya Victoria. .
Malowa, omwe tsopano akuganiziridwa kuti ndiwo akale kwambiri ku North America, anali ndi zida, mbedza za nsomba, mikondo, ndi moto wophikira wokhala ndi makala ambiri omwe anthu akalewa ayenera kuwotcha. Zida zamakala zinali zofunika kwambiri chifukwa zinali zosavuta kupanga tsiku la carbon.
Kodi n'chiyani chinawabweretsa kumalo enieni amenewa? Ophunzira a payunivesiteyo anamva nkhani yakale yosimba za anthu a mtundu wa Heiltsuk, omwe anali a m’derali. Nkhaniyi ikuti panali kagawo kakang'ono ka nthaka komwe sikamaundana, ngakhale mu Ice Age yapitayi. Zimenezi zinakopa chidwi cha ophunzirawo, ndipo anayamba kufufuza malowo.
Mneneri wa gulu lachilengedwe la Heiltsuk First Nation, a William Housty, akuti "n'zodabwitsa kwambiri" kuti nkhani zomwe zimaperekedwa kuchokera ku mibadwomibadwo zinapangitsa kuti asayansi atulukire.
"Kupeza kumeneku ndikofunika kwambiri chifukwa kumatsimikiziranso mbiri yakale yomwe anthu athu akhala akunena kwa zaka zikwi zambiri," akutero. Nkhanizi zidafotokoza za Triquet Island ngati malo opatulika osakhazikika chifukwa madzi am'derali adakhazikika kwa zaka 15,000.
Fukoli lakhala likusemphana maganizo kwambiri pankhani ya ufulu wa malo ndipo Housty akuwona kuti adzakhala olimba m'tsogolomu osati nkhani zapakamwa komanso umboni wa sayansi ndi geological wowathandiza.
Kupezaku kungapangitsenso ofufuza kuti asinthe zikhulupiriro zawo pankhani ya njira zosamuka za anthu oyambirira ku North America. Anthu ambiri amakhulupirira kuti anthu akawoloka mlatho wakale wa malo omwe kale ankagwirizanitsa Asia ndi Alaska, ankasamukira kum’mwera wapansi.
Koma zatsopano zomwe zapezedwa zikusonyeza kuti anthu ankagwiritsa ntchito mabwato kudutsa m’mphepete mwa nyanja, ndipo kusamuka kumtunda kunabwera pambuyo pake. Malinga ndi Gauvreau, "Zomwe zikuchita ndikusintha lingaliro lathu la momwe North America idakhalira anthu oyamba."
M'mbuyomu, zizindikiro zakale kwambiri za anthu a Heiltsuk ku British Columbia zinapezeka mu 7190 BC, pafupifupi zaka 9,000 zapitazo-zaka zonse za 5,000 kuchokera pamene zinthuzo zinapezeka pa Triquet Island. Panali anthu pafupifupi 50 a Heiltsuk kuzilumba zozungulira Bella Bella m'zaka za zana la 18.
Iwo ankakhala ndi moyo pa chuma cha m’nyanja ndipo anayamba kuchita malonda ndi zilumba zoyandikana nawo. Pamene Hudson's Bay Company ndi Fort McLoughlin zinakhazikitsidwa ndi Azungu, anthu a Heiltsuk anakana kuthamangitsidwa ndipo anapitirizabe kuchita nawo malonda. Fukoli tsopano lili ndi gawo lomwe a Hudson's Bay Company amauza pomwe okhazikika ake adafika.
