Scientists Have Revived Cell Parts From A 28,000-Year-Old Extinct Woolly Mammoth

Although we have seen mammoths in books and movies, we have never seen them in real life since they are extinct. 

This story is about a mammoth named Yuka, who lived 28,000 years ago. Yuka’s remains were found in frozen permafrost in the wastelands of Northern Siberia.

The woolly mammoth which is one of the last mammoth species to have lived in the Pleistocene period until its destruction in the Holocene epoch. It was one of the last mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene.

It was in around 2010 that Yuka’s remains were found in an icy tomb. Through implanting the mammoth’s cell nuclei into mice egg cells, scientists from Japan have succeeded in awakening traces of biological activity in this mammoth. 

According to the researches done by genetic engineer Kei Miyamoto from Kindai University, even though time has passed by, cell activity can still occur, and parts can be created again.

They extracted muscle tissue and bone marrow from the frozen remains, then inserted nucleus like structures in a comparatively better condition into living mouse germ cells (oocytes).

Using 273.5 milligrams of mammoth tissue, the researchers managed to collect 88 nuclei structures. The few that were injected into egg cells showed signs of cellular activity that leads to cell division. When examining the reconstructed oocytes, Yako’s nuclei presented histone incorporation, spindle assembly, and partial nuclear formation.

But they couldn’t find any signs of the full activation of nuclei for cleavage. The researchers concluded that cell nuclei could sustain for over 28,000 years, at least even partially.

Miyamoto believes that this is a giant step towards bringing mammoths back to life. But this might take a long time. 

Their next step is to move on to cell division. Less-damaged nuclei will then enable DNA replication and transcription. Technology also plays a vital role in proceeding further. Maybe someday, in the future, we will see mammoths roaming on the Earth as they used to a long time ago.

Although pterosaurs are close relatives, they are not actual dinosaurs. Even more distantly linked to dinosaurs are the marine reptiles, which include the plesiosaurs and ichthyosaurs. Mammoths and mastodons are mammals and didn’t appear until millions of years after the Cretaceous period.

Evidence suggests that humans hunted mammoths, although rarely. It appears that they would have been dangerous animals to attack.

An extinct 2000-year-old seed was found in a clay jar that brought a Biblical tree Back to life. The tree was a staple crop in the Kingdom of Judea. The Judean palm trees were served as one of the kingdom’s symbols of good fortune. It was used as an aphrodisiac and regarded as a symbol of fertility. How awesome is that!?
