In just the last several months, de-extinction—bringing back extinct species by recreating them or organisms that resemble them—has moved closer from science fiction to science fact. —an American for-profit de-extinction startup headed by geneticists George Church and Beth Shapiro—announced two major achievements almost back-to-back.

In the first, scientists spliced part of the wooly mammoth's genome into mice to create "," incredibly cute pom-pom-like rodents sporting coats that express the genes of long-extinct wooly mammoths.

Just a few weeks later, Colossal announced an even bigger achievement, , a contemporary of the wooly mammoth who, like their co-travelers, last roamed Earth roughly 10,000 years ago.

Mammoth popularity

Wooly mammoths are at the forefront of these controversial de-extinction efforts. Despite a deep bench of more recently extinct species— and a whole host of others—readily available to take center stage in de-extinction efforts, wooly mammoths figure prominently in de-extinction stories, both scientific and popular.

Wooly mammoths featured prominently in the imagery of , a "genetic rescue" conglomerate of scientists and futurists headed by tech-guru Steward Brand; in 2021, Colossal "established ownership" . Colossal's own logo visualizes CRISP-R, the gene-splicing technology that facilitates de-extinction, and the signature spiraled tusks of Mammuthus primigenius.

In popular culture, wooly mammoths have been a source of fascination for the last several centuries. that live mammoths would be found beyond the frontier of American colonialism in the late-1700s, while were major events in the early 1800s. American painter Charles Willson Peale captured the , and later capitalized on that mastodon's skeleton in his Philadelphia museum.

More recently, featured in the , first launched in 2002.

Climate icons

At the same time, wooly mammoths have also become an emblem of the contemporary climate crisis. During the recent wave of in order to draw attention to the climate crisis, environmental activists painted the (fortunately artificial) tusks of the Royal B.C. Museum's .

In a 2023 publicity stunt, the Australian cultured-meat startup, Vow, unveiled a mammoth meatball produced out of the wooly mammoth's genome with sheep DNA as filler. Not for sale, was scorched before an audience at the Dutch science museum, Nemo.

The stunt was intended to call attention, again, to the plight of Earth's climate, the unsustainability of industrialized food systems and the potential for lab-grown meat to .

Model animals

For a creature that no human being has ever seen live and in the flesh, wooly mammoths certainly get a lot of media exposure. How did this long-extinct species become the emblem of contemporary extinction and de-extinction?

People have been interacting with the remains of wooly mammoths for hundreds of years. Dig a hole deep enough almost anywhere in the northern hemisphere, and you are apt to come across the bones or maybe the tusks of extinct mammoths or mastodons.

In early modern Europe, mammoth fossils were famously interpreted as the before being recognized as belonging to elephant-like creatures around 1700. Only around 1800 were mammoths recognized as a distinct and extinct species of proboscidea.

Elsewhere in Arctic regions, especially Siberia, . As rivers and their tributaries surged during annual thaws, whole carcasses of mammoths (and wooly rhinos) were sometimes exposed.

Local peoples who came across these remains, apparently recently dead but belonging to creatures they never saw walking Earth's surface, surmised that they were great burrowing rodent-like animals that tunneled through the ground and perished if they accidentally came into contact with atmosphere.

Around the Arctic, including in Alaska, permafrost prevented the fossilization of mammoth tusks as well as bodies, and this , carved locally and exchanged into historically regional, and now global, markets.

Continued relevance

Despite their association with the distant past, wooly mammoths have long resonated with modern human cultures as their fossilized or preserved body parts entered economic practices and knowledge systems alike. But as the extinction of once numerous species like the , the and African elephant began to loom over the late 19th century, wooly mammoths took on new meanings in the context of modern extinction and emergent understandings of human evolution.

Revolutions in geology, archaeology, paleontology and related disciplines were changing long-held assumptions about the origin of humankind.

Narratives of the rise of "" arose in natural history institutions such as the American Museum of Natural History and the Field Museum in Chicago. These origin stories were explicitly connected to the presumed extinction of wooly mammoths and their evolutionary relatives, the mastodons.

These led to some of the most powerful expressions of mammoths in visual form, like the frescoes and paintings produced by renowned paleoartist Charles R. Knight.

At the same time, cave paintings in France, Spain and elsewhere came to light in the early 20th century. For example, the , clearly depicting wooly mammoths were interpreted as further evidence of this deep and powerful historical connection.

It is this connection—the association of the rise of modern humankind with the decline and extinction of the wooly mammoth—that feeds today's continued fascination. Notions of human complicity in extinction stories have long been embedded in modern scientific understandings of wooly mammoths. It is no accident that wooly mammoths are so central to de-extinction projects and climate activism alike.
