Chaiyo-hupenyu Jurassic Park: Kutsakatika kweMhuka dzekare 335p5m
Zvinoita sekunge tiri kurarama mubhaisikopo guru rakaiswa kuma3000s. Pfungwa ye Colossal Bioscience ndeyekudzosa mhuka dzakatsakatika kuhupenyu kuburikidza nemaitiro ekugadzirisa magene, ayo anoenda nezita re Crispr uye inoshanda semhando yechigero chemajini. Mukuita, masayendisiti akakwanisa kuita DNA genome editing vachishandisa hwaro hunowanikwa mumafossils emhumhi aigara munguva pakati. 11,5 zviuru uye 72 zviuru zvemakore, inonziwo Dire Wolf.
Mubvunzurudzo na Time Magazine, masayendisiti akataura kuti kuburikidza nekugadzirwa kwemajini aya, endothelial progenitor masero (EPCs) akaunganidzwa kubva muropa rehumwe grey wolf. Vakabva vagadzirisa, zvichibva pane zvakawanikwa mumafossils, 20 majini anokosha kubva mumasero aya kuti aenderane neDNA yemapere akaoma, pasina kuisa zvinhu zvekare zvekare.
Zvino, maDNA akagadziridzwa aya akaiswa mumazai asina kuvharwa, achigadzira mazai akatakurwa nembwa dzehadzi dzine hutano, hombe dzakasanganiswa. Vana vaviri vekutanga vakazvarwa muna Gumiguru 01, 2024 uye parizvino vane mwedzi mitanhatu yekuzvarwa, vaine mazita e Romulus uye Remus, yakatumidzwa zita renhau yechiGiriki yehama mbiri dzakarerwa neshe-mhumhi. Ona mifananidzo yavo pazasi:
Yechitatu yakasikwa zvakare dire wolf inonzi khaleesi, tichireva Mutambo Wechigaro. Akazvarwa muna Ndira 31, 2025. Ona mufananidzo wake pazasi:
Via X, kambani yakaita chinyorwa chinoratidza kukosha kwemaitiro uye kuratidzawo vhidhiyo. Ona zvakadhindwa uye kududzira:
KUSVIRA. Uri kunzwa kuchema kwekutanga kwemhumhi yakaoma mumakore anopfuura 10.000. Sangana naRomulus naRemus, mhuka dzekutanga dzakatsakatika, dzakazvarwa muna Gumiguru 1, 2024.
Dire wolf yakatsakatika kwemakore anopfuura 10.000. Mhumhi mbiri idzi dzakadzoswa kubva mukutsakatika pachishandiswa genetic edits yakatorwa kubva kune yakazara dire wolf genome, zvine hungwaru yakavakwazve naColossal kubva kuDNA yekare yakawanikwa mumafossils ekare 11.500 uye 72.000 makore.
Nguva ino haingoratidzi chiitiko chakakosha kwatiri sekambani, asiwo kusvetukira mberi kwesainzi, kuchengetedza uye vanhu. Kubva pakutanga, chinangwa chedu chave chakajeka: "Kushandura nhoroondo uye kuve kambani yekutanga kubudirira kushandisa tekinoroji yeCRISPR kutsakatisa mhuka dzakamborasika." Mukuita izvi, tinoenderera mberi nekufambisira mberi basa redu rakakura: kubvuma basa revanhu rekudzorera Nyika kune hutano.
Asi iyi haisi nguva yedu chete - inguva yesainzi, yepasi redu, uye yevanhu. Zvese zvatinoda uye zvatinoda nazvo. Zvino, vhara maziso ako uye uteerere kuchema ikoko zvakare. Funga kuti izvi zvinorevei kwatiri tose.

Kunyange zvazvo yakabudirira, mubvunzo mukuru munharaunda yesainzi ndeyekuti nzira ye "de-extinction" ye-dire wolf yakaitwa sei. Izvi zvinodaro nekuti, kusvika parizvino, ongororo yakadzama yekuti chirongwa che "de-extinction" chakaitwa sei hachisati chaburitswa mumapepanhau akadai se. muzvarirwo, kutsanangura uye kuunza bvunzo dzakaitwa panguva yekudzidza. Naizvozvo, genetics masayendisiti haagone kusimbisa kana "de-extinction" yakaitika chaizvo.
Parizvino, vana vanogara munzvimbo yakasarudzika inoyera 809 zviuru m², isina nzvimbo yakaburitswa, asi yakajairwa kumagariro avo echisikigo kuti vakure vaine hutano hwakakwana.
Jeremy Austin, mutungamiriri weAustralian Center for Ancient DNA, akataura kuti, mukuita, kambani yeColossal yakangogadzira grey wolf yakagadziridzwa kuti ifanane nepfungwa yake yemhumhi yakaipa. Webhusaiti Sayenzi Yekuzivisa Inorangarirawo mutsara unozivikanwa nenyanzvi dzenyeredzi nesainzi Carl Sagan: "zvichemo zvinoshamisa zvinoda humbowo hunoshamisa". Zvisinei neizvi, maitiro akaudzwa muvhidhiyo yemaminetsi gumi neimwe yakatumirwa pane yekutanga YouTube chiteshi:

Mhumhi yakaoma (Aenocyon dirus) chaive chikara chikuru cheIce Age. Yainyanya kugarwa kuNorth America, ichichinjika kune dzakasiyana siyana dzakaita semapani, masango nenzvimbo dzemahombekombe.
Zvisaririra zvinowanikwa munzvimbo dzakadai La Brea Ranch (California) inoratidza kuti yaive mhuka yakasimba, ine shaya dzine simba uye hunhu hwekugarisana hwakafanana nehwemapere emazuva ano, kuvhima hombe megafauna herbivores mumapoka.
Chimiro chayo chairema uye chine mhasuru kupfuura yemazuva ano mapere, izvo zvakaita kuti ishande pakuvhima munzvimbo dzakavhurika uye kutarisana nemhuka huru. Mazino avo neshaya zvakagadziridzwa kwete zvekuuraya chete asiwo zvekutyoka mapfupa, izvo zvakawedzera kudya kwavo. Fossil humbowo hunoratidza kuti dire wolf yaive muvhimi akabatana, inogona kunge yakave yakakosha mukana panguva yePleistocene.
Kuparara kwemhumhi yakaipa kwakaitika pakutanga kweHolocene, zvichida nekuda kwekukurumidza kuchinja kwemamiriro ekunze, kupera kwe megafauna iyo yakashanda sezvokudya, uye kuwedzera kuvapo kwevanhu.

Muna Kurume wegore rino, kambani imwe chete iyi yakazivisa kusikwa kwembeva dzakagadziridzwa machira ane makushe akafanana neaya ewool mammoths, rudzi rwakatsakatika zviuru zvina zvemakore apfuura. Pfungwa iri pano haisi yekuratidza kuti mammoths achadzoserwa kuhupenyu usiku humwe, asi pane kuratidza kuti, kuburikidza nekugadziriswa kwemajini, zvinokwanisika kutora mukana wehunhu hwemhuka yakaparara makore apfuura.
Mbeva inokura murabhoritari ine mvere dzakafanana nedzewool mammoth dzaikwanisa kuburitsa carbon dioxide, greenhouse gasi. Mukutsvaga, masayendisiti akaongorora genomes akatorwa kubva kune zvakasara zvemammoth akawanda, pamwe chete nehama mhenyu uye dzakatsakatika, kuona shanduko yemajini yakashandura mapuroteni mukushanduka kwemhuka idzi. Tarisa:
Ongororo dzekutanga dzakaguma nekusikwa kwemaembryo mazana maviri nemakumi mashanu, ayo asingasviki hafu akasvika padanho rekukura, achigadzira zvimiro zvinogoneka zvine maseru anosvika mazana maviri kusvika mazana matatu. Mazamu aya akabva aiswa muchibereko chevakadzi vanenge gumi nevaviri vakatsivana.
Kuita kwacho kwakaguma nekuzvarwa kwevana makumi matatu nemasere embeva. Yese yakabudirira kuratidza maitiro emammoth, akadai segoridhe, makushe emvere uye accelerated lipid metabolism - hunhu hune chekuita nekuchinjika kune kutonhora kwakanyanya.
Nekururamisa kwe "kumutsa" mhuka dzakatsakatika kuti dzidzorere kuenzana kwezvakatipoteredza kwePasi, kambani yanga ichitsvaga mari yekutsigira tsvagiridzo yayo. THE Colossal Biosciences ine mutengo wemusika weUS$ 10 bhiriyoni, ingangoita R$ 59 bhiriyoni mukushandurwa kwakananga.
KuColossal, kutsakatika hakusi kungoita chipenyu chiri kana kuti chakafanana nerudzi rwakatsakatika. Ndezve kubatanidza zvipenyu zvakasiyana-siyana zvekare nekuvandudzwa kwezvino mukuedza kugadzira ramangwana rakagadzikana.
