Ska\u013c\u0161 pazi\u0146ojums par renesanses \u0123\u0113niju<\/p>\n
Starptautiska p\u0113tnieku komanda pazi\u0146ojusi par potenci\u0101li noz\u012bm\u012bgu atkl\u0101jumu, kas var\u0113tu main\u012bt izpratni par renesanses di\u017egaru Leonardo da Vin\u010di. P\u0113tnieki apgalvo, ka vi\u0146iem izdevies ieg\u016bt DNS p\u0113das no renesanses laikmeta z\u012bm\u0113juma un v\u0113sturisk\u0101m \u0123imenes dokumentiem, kas var\u0113tu b\u016bt saist\u012btas ar pa\u0161u m\u0101kslinieku. \u0160is atkl\u0101jums, lai gan v\u0113l ir provizorisks un nav izg\u0101jis pilnu zin\u0101tnisk\u0101s recenz\u0113\u0161anas procesu, paver jaunas iesp\u0113jas m\u0101kslas darbu autentifik\u0101cijas jom\u0101.<\/p>\n
Metode un \u0123en\u0113tiskais savienojums<\/p>\n
P\u0113t\u012bjums, kas ir da\u013ca no pla\u0161\u0101kas Leonardo da Vin\u010di DNS projekta (LDVP), ir izmantojis minim\u0101li invaz\u012bvas metodes, lai ieg\u016btu biolo\u0123isko materi\u0101lu no kult\u016bras artefaktiem. Zin\u0101tnieki izmantoja sterilas tamponu koci\u0146us, l\u012bdz\u012bgus tiem, kas tiek izmantoti COVID-19 testos, lai sav\u0101ktu DNS paraugus no str\u012bd\u012bga sarkan\u0101 kr\u012bta z\u012bm\u0113juma ar nosaukumu “Sv\u0113tais b\u0113rns”, kas tiek pied\u0113v\u0113ts da Vin\u010di, k\u0101 ar\u012b no 15. gadsimta v\u0113stul\u0113m, ko rakst\u012bjis k\u0101ds no Leonardo \u0123imenes v\u012brie\u0161u k\u0101rtas radiem. Anal\u012bze koncentr\u0113j\u0101s uz Y hromosomu, kas tiek nodota no t\u0113va d\u0113lam. P\u0113tnieki atkl\u0101ja, ka abos paraugos \u2013 gan z\u012bm\u0113jum\u0101, gan v\u0113stul\u0113s \u2013 atrast\u0101 DNS pieder pie vienas haplogrupas, proti, E1b1b. \u0160\u012b \u0123en\u0113tisk\u0101 l\u012bnija ir izplat\u012bta Tosk\u0101n\u0101, Leonardo dzimtaj\u0101 re\u0123ion\u0101. Tas liecina par kop\u012bgu sen\u010du izcelsmi.<\/p>\n
Skeptiskais skat\u012bjums un izaicin\u0101jumi<\/p>\n
Neskatoties uz aizraujo\u0161ajiem rezult\u0101tiem, zin\u0101tnieki uzsver, ka \u0161ie atradumi v\u0113l nav gal\u012bgs pier\u0101d\u012bjums tam, ka ieg\u016bt\u0101 DNS pieder Leonardo da Vin\u010di. “Viennoz\u012bm\u012bgas identit\u0101tes noteik\u0161ana ir \u0101rk\u0101rt\u012bgi sare\u017e\u0123\u012bta,” nor\u0101da Florences Universit\u0101tes antropologs un sena DNS speci\u0101lists Deivids Karamelis, kur\u0161 piedal\u0101s projekt\u0101. Vi\u0146\u0161 skaidro, ka z\u012bm\u0113jums, t\u0101pat k\u0101 citi artefakti, laika gait\u0101 var\u0113ja non\u0101kt saskar\u0113 ar daudziem cilv\u0113kiem, kuriem var\u0113tu b\u016bt bijusi t\u0101da pati \u0123en\u0113tisk\u0101 l\u012bnija. Leonardo nav zin\u0101mu tie\u0161o p\u0113cn\u0101c\u0113ju, un vi\u0146a apbedz\u012bjuma vieta Francij\u0101 tika ne reizes trauc\u0113ta 19. gadsimta s\u0101kum\u0101, t\u0101d\u0113\u013c nav dro\u0161u palieku tie\u0161ai DNS sal\u012bdzin\u0101\u0161anai. Lai p\u0101rvar\u0113tu \u0161os izaicin\u0101jumus, zin\u0101tnieki analiz\u0113 DNS no dz\u012bviem Leonardo t\u0113va p\u0113cn\u0101c\u0113jiem un izp\u0113ta kaulus, kas atrasti \u0123imenes kapen\u0113s Tosk\u0101n\u0101.<\/p>\n
