Woolly mammoth - Siegfried - 06-02-2014
This is interesting...

But is it morally right? or even a good idea?

Nice Find Siegfried,
I don't think it is right, I also believe that despite of their claim it will not be possible to bring them back.

Woolly mammoths could roam the earth again someday thanks to research reported Monday, where cell nuclei from one of the long-extinct animals showed biological activity when transplanted into mouse cells.
Bone marrow and muscle tissue were extracted from the remains of a mammoth named Yuka that had been frozen in Siberian permafrost for 28,000 years in the study, published online in the journal Scientific Reports.
Genomic DNA was compared against that of elephants, and the researchers confirmed that Yuka's DNA overlapped with the DNA and proteins specific to mammoths.
The team injected cell nuclei from the muscle tissue into mouse egg cells and observed the forming of structures that appear just before cell division starts. The researchers also found possible signs of repair to damaged mammoth DNA.
This marks a "significant step toward bringing mammoths back from the dead," said researcher Kei Miyamoto, one of the study's authors.
"We want to move our study forward to the stage of cell division," said Miyamoto, who acknowledged that "we still have a long way to go" before the Ice Age species can return.
The team from Kindai University, in greater Osaka, is collaborating with a Russian institution on the work using a cloning technology called somatic cell nuclear transfer.

Pits built by humans about 15,000 years ago that were filled with bones of at least 14 mammoths have been found in the neighbourhood of Tultepec, north of Mexico City: https://www.cbc.ca/news/technology/mammoth-traps-1.5331381, https://edition.cnn.com/travel/article/mammoth-hunting-mexico-scli-intl-scn/index.html, https://www.theguardian.com/world/2019/nov/07/mammoth-trap-mexico-prehistoric-hunting-pits

'Resurrected' mammoth DNA helps explain why the species went extinct
Reviving the woolly mammoth is still a tall order. However, technology might be far enough along to help explain why the elephant precursor went extinct in the first place. Scientists have 'resurrected' genes from a population of mammoths that survived on a Siberian island until around 4,000 years ago to see what might have contributed to this relic herd dying out. After resurrecting a mammoth's genes through cells in culture, they compared it against both other mammoths and Asian elephants to look for problematic mutations based on known genetic behavior.
As it turns out, at least one of the island's mammoths had a string of genetic defects. There were issues with male fertility, neurological development, insulin signalling and even the ability to smell flowers. This suggests the mammoths might have been hurt by their small population size (300 to 500) and isolation from the Siberian mainland, reducing their long-term chances of survival.
This doesn't provide a full explanation for why woolly mammoths finally died out. Most of them (along with other species) were wiped out by a changing climate that eliminated the tundra they needed to survive. It paints a clearer picture, though, and suggests technology could help solve other prehistoric mysteries.
