Life-sized recreation of a Woolly Mammoth.
A Dallas-based startup named Colossal wants to bring the Woolly Mammoth back to life. It’s not as crazy as it sounds, and Colossal has raised $15 million to fund the project.
If everything goes to plan, we could see the first creature in 2027 and who knows what else? Maybe herds of Mammoth thundering across the tundra by 2040—if there’s any tundra left.
CNET reports that the plan is more scientifically realistic than a basic description makes it seem:
The plan isn’t to re-create true woolly mammoths exactly but rather to bring their cold-adapted genetic traits like small ears and more body fat to their elephant cousins, creating a hybrid that can wander the tundra where mammoths haven’t been seen for 10,000 years. Colossal’s co-founders are Chief Executive Ben Lamm, who started five companies before this, and George Church, a Harvard Medical School professor with deep CRISPR expertise.
CRISPR needs some explanation here. It has nothing to do with crunchy food and it’s not those drawers in the bottom of most refrigerators.
CRISPR is an acronym for “clustered regularly-interspaced short palindromic repeats.” It’s still a fairly new form of technology. New Scientist explains:
The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell. After that, the next step in CRISPR gene editing is usually to alter that piece of DNA. However, CRISPR has also been adapted to do other things too, such as turning genes on or off without altering their sequence.
Essentially, the brains behind Colossal’s efforts will use what’s already there—elephants—to make cold-adapted woolly cousins that can populate the arctic regions where the original mammoths roamed. Actually cloning a mammoth is off the table, reports CNN, because “the DNA that scientists have managed to extract from woolly mammoth remains frozen in permafrost is far too fragmented and degraded.”
The reasoning behind this effort has everything to do with climate change. According to the same CNN article about Colossal’s fundraising, those in favor of this effort believe that “bringing back the mammoth…could help restore the fragile Arctic tundra ecosystem, combat the climate crisis, and preserve the endangered Asian elephant, to whom the woolly mammoth is most closely related.”
To say the project is fraught with ethical challenges would be putting it mildly. They include:
It’ll really still be an elephant, not a true Mammoth. As one researcher said to CNN, this will be “a hairy elephant with some fat deposits.”
The same researcher questioned using elephants as surrogates, saying elephants and mammoths are “as different as humans and chimpanzees.”
If this really is a form of “de-extinction,” a group of scientists argued back in 2017 that such an effort could cause “sacrifices in conservation of [existing] species” and that point “should be a crucial consideration in deciding whether to invest” in doing something like making new age mammoth.
That’s a short list of what Colossal has to address to make this dream a reality. Entrepreneur Ben Lamm …read more
