Woolly Mammoth: 2027, the year of resurrection

It seemed like a boutade, but Colossal has raised the necessary funds and is preparing for the genetic resurrection of the Woolly Mammoth within 4 years.

READ THIS IN:

After the first, bombastic announcement of September 2021, the scientists of the Colossal laboratory (under the orders of that Dr George Church which we know well) also dissolves reservations on the timing. The woolly mammoth, extinct for millennia, is ready to walk the planet again in just four years after a "genetic resurrection".

The turning point came from a new 60 million dollar loan raised a few months ago. 2027 is just around the corner, say the researchers of the Dallas startup: and after the woolly mammoth, the next candidate for resurrection is the Tasmanian tiger, which became extinct in 1936.

Just one question: why?

Colossal's declared goal is not to bring the mammoth back to life for the joy of zoos and theme parks (although… Oh well, we'll see), but to reintroduce it to its ancient habitat, the Arctic, to protect the ecosystem .

At this point, the question shifts from "why" to "how". And in this regard, Church's first statements, which we reported at the time of the announcement, are authentic. The "genetically resurrected" woolly mammoth will essentially be a cold-resistant elephant (even at -40°C), but will still behave like its putative ancestors.

How CRISPR can feed the planet

"It will walk like a woolly mammoth and look like one, but more importantly, it will be able to inhabit the same ecosystem previously abandoned by the mammoth's extinction," the company explains. on its website.

How the genetic resurrection of the woolly mammoth works

One detail that says it all: the woolly mammoth shares 99,6% of its DNA with the Asian elephant. Colossal intends to genetically modify its cells by hybridizing them with the DNA of a perfectly preserved woolly mammoth.

The genetic editing technique used will be the now famous one and award-winning CRISPR. Colossal will develop a hybrid elephant-mammoth embryo and transfer it into an African elephant, which is larger than the Asian elephant and will be a better surrogate for the mammoth. At that point, scientists say, once the cute arctic pachyderm is resurrected, it will be ready to help the environment.

I insist: how?

Mammoth ancestors used to graze, kicking up the ice and snow pack and essentially stimulating the growth of plants and trees. Without its presence, many plants have lost the ability to thrive in a freezing climate and to absorb excess CO2.

Because of this Colossal goes so far as to describe the woolly mammoth as a "vital defender of the earth".

Let's see if the game will be worth the candle: we'll find out soon, there are only four years to go.
