'Woolly mammoth' will be back from extinction within two years, say Harvard scientists

"Woolly mammoths" could be brought back from extinction within two years, the scientists behind a groundbreaking resurrection project have said.
World-renowned geneticist Prof George Church and his team at Harvard University have been working for the past two years on recreating the DNA blueprint of the mammoth.
They have used DNA from mammoths that were preserved in Arctic permafrost to look for the genes that separated them from elephants, such as those with code for a shaggy coat, big ears and antifreeze blood.

He added: “Our aim is to produce a hybrid elephant/mammoth embryo. Actually it would be more like an elephant with a number of mammoth traits. We’re not there yet, but it could happen in a couple of years.” 
The woolly mammoth roamed across Europe, Asia, Africa and North America during the last Ice Age and vanished  4,500 years ago, probably due to a combination of climate change and hunting by humans.
Their closest living relative is the Asian, not the African, elephant.
“De-extincting” the mammoth has become a realistic prospect because of revolutionary gene editing techniques that allow the precise selection and insertion of DNA from specimens frozen over millennia in Siberian ice.
Prof Church helped develop the most widely used technique, known as CRISPR/Cas9, that has transformed genetic engineering since it was first demonstrated in 2012.
Derived from a defence system bacteria use to fend off viruses, it allows the “cut and paste” manipulation of strands of DNA with a precision not seen before.
Dr Edze Westra, senior lecturer and Crispr expert at the University of Exeter, said: "What George Church is doing in trying to revive particular species I think represents a massive opportunity. 
"One can also use this technology for engineering the DNA of rapidly declining species or those that are becoming too inbred to increase their chance of survival.

Prof Church, a guest speaker at the meeting, said the mammoth project had two goals - securing an alternative future for the endangered Asian elephant and helping to combat global warming. 
Woolly mammoths could help prevent tundra permafrost from melting and releasing huge amounts of greenhouse gas into the atmosphere.
“They keep the tundra from thawing by punching through snow and allowing cold air to come in,” said Prof Church. “In the summer they knock down trees and help the grass grow.”

Budalaština! Već se u tekstu vidi da se ne radi o vunastom mamutu, već hibridnoj vrsti. Nego, čime će se hraniti? Ono što mnogi ne znaju je da u ledenom dobu tlo nije bilo pod sniegom, već je bilo pokriveno travom i mahovinom, time su se hranili. Jedan od razlogah izumiranja je što je s dolaskom toploga doba počel padati snieg koji je pokril tlo pa mamuti nisu mogli doći do hrane.

Pa oni smatraju da globalnim zagrijavanjem ima sve manje snijega a kako je projeket cca 10 godina oni su sigurno da klima u sibiru će biti sasvim odgovarajuća za hibrid mamute

Koliko vidim, ideja je da mamuti sprieče otapanje vazdaleda. Ako tlo bude zaleđeno, što će jesti? Pitanje je načeno, jasno mi je da ti ne znaš.

Pa sibir nije baš pustinja to je izuzetno gusta močvarna nepregledna šuma breze i četinara

tamo je glavni problem zima i komarci, komarci kažu da su još gori to je nevjeropjatno

Ako tko zna o komarcima, to su Osječani. :)

Jasno je da su mamuti jednostavno izlovljeni od strane ljudi.  Troma i laka a obilata lovina koja može hraniti 

pleme cilu zimu. U Africi nisu izlovljeni jer se meso nije moglo čuvati duže vrimena a ima i drugih izvora 

bjelancevina, rogate marve i divljači. 

     Azijski slon je izgubio kljove baš zato jer su lovili one sa većim kljovama pa su genetski 

 ostali samo oni sa malim kljovicama. 

   Bedastoće o tome kako bi NEO Mamuti spasili klimu jer bi gazili snijeg i sl budalaštine.....to neću 

komentirati dalje

Ako je izumiranje uzrokovalo pleme, okrivimo Levija.

levi i pleme peru ruke, kod nas se nigdje ne spominju mamuti, bizoni da, cak i neki tigrovi  al u medjurecju takove zivotinje nisu hodile, nit nesto blizu slonu

veliki je rizik kloniranje mamuta,to je mrcina stara 10 000 godina i ko zna kakvi su tad zemljom plutali virusi,i sad to vracati nazad,mogli bi gadno najebati,mi smo neotporni na viruse od prije 10 000 godina,to bi nas pokosilo ko spanjolska groznica ako ne i gore.

Ne spominjete ih zbog grižnje savjesti.
