Domestication is often treated like a chapter of ancient history, something humans completed thousands of years ago with wolves, cattle, and pigs. But the process has never actually stopped, and right now, across the globe, several wild species are already on the path toward becoming the next domesticated animals. Domestication is not the same as taming. A tamed animal is anindividual raised to tolerate humans, but domesticationis a genetic process that reshapes an entire population over generations.
The classic proofis the Soviet fox experiment, which began in the 1950s. By selectively breeding only the tamest foxes, scientists saw dramatic physical changes within just a few generations, including floppy ears, spotted coats, and dog-like behavior. This shows that domestication can happen much faster than once believed, provided the right conditions are met. .
For any species to become domesticated, it must meet several key criteria. It must be able to breed in captivity easily, which rules out animals like giant pandas and cheetahs. It needs a flexible diet, eliminating picky eaters like koalas. It requires a relatively calm temperament, or at least enough variation in temperament for selective breeding to work.
And crucially, it needs a social structure that humans can slot into, ideally a hierarchical herd dynamic. Zebras famously fail this test, as nearly every individual is aggressivelyunpredictable, making them statistically more dangerous to zookeepers than lions. . Among the most likely candidates for full domestication today is the fox.
Beyond the famous Russian experiment, urban fox populations aroundtheworld are already evolving naturally. City foxes have become noticeably bolder, more curious, and better at reading human cues than their rural counterparts, selection happening without any deliberate human effort. With just a few thousand years and some intentional breeding, experts consider them the most plausible next step toward becoming a fully domesticated companion, an animal that essentially wants to become a dog but simply hasn’t arrived yet. Crowsavemay not seem likeobvious candidates, but they possess startling intelligence that makes thema serious contender.
They recognize individual human faces, hold grudges, leave gifts for people who feed them, and even teach their offspring which humans to trust. Urban crows already exploit human infrastructure, timing their activities around garbage collection days and using traffic to crack nuts at pedestrian crossings, positioning themselves precisely where tires will crack the shells without crushing them. Their social structures differ from herd animals, but they form long-term partnerships, raising the question of whether selective breeding could produce crows deeply bonded to humans. Given their proven adaptability, a domesticated crow seems both remarkable and slightly unsettling, fittingly consistent with their nature.
The capybara, the world’s largest rodent, has already partially walked the path toward domestication. These highly social, semi-aquatic animals live in structured groups, communicate constantly, and are already kept as pets in many countries. They graze on grass, making their diet extremely manageable, and they coexist peacefully with countless other species, often serving as living furniture for birds, monkeys, and ducks. Their main hurdles are a need for regular access to water and their still-wild instincts, but all the core components for domestication are present.
A dedicated breeding program focusing on tameness could plausibly produce a recognizable domesticated capybara within about a hundred generations, which is comparatively brief on an evolutionary timescale. The octopusis perhaps the most uncomfortable candidate, but domestication has never been solely about companionship. The vast majority of domesticated animals throughout history have been food. Octopuses arealready being farmed, with research institutions, particularly in Spain, working to close their life cycle in captivity across multiple generations.
Crucially, octopuses display individual personalities, some shy, some aggressive, some curious, and they recognizeren individual humans, reportedly squirting water at ones they dislike. This existing temperament variation provides raw material for selective breeding. Their challenges are immense, including short lifespans, cannibalistic tendencies, legendary escape skills, but their flexible diet and increasing captive breeding success mean a farmed, selectively bred octopus is not impossible, and impossibility has never stopped a domestication story before. Deer also present a serious contender, particularly because humans have already come remarkably close before.
Reindeer, part of the same family, have been herded, managed, and selectively bred by Arctic peoples for thousands of years, though they remain not fully domesticated. White-tailed deer in American backyards arealready adapting to human environments, losing their fear and learning to use human infrastructure as a food source. Red deer and elk are already farmed commercially in many countries, with breeding programs and infrastructure alreadyin place. Deer are social herd animals with clear hierarchies, flexible diets, and breed readily in captivity, but their seasonal breeding cycles and dangerous antlers complicate year-round management.
Still, for agricultural purposes, they stand as a serious candidate for domestication within the next few centuries. Elephantsrea more deceptive case. Humans have used them for millennia in war, labor, and ceremony, but almost every working elephantin history was captured wild and tamed, often brutally, which is taming, not domestication. Truly domesticated elephants, genetically distinct from wild populations due to generations of captive breeding, essentially do not exist yet.
The potentialis immense, given their exceptional intelligence, complex emotional lives, and capacity for deep bonds with humans, but their biology presents enormous obstacles. They take fifteen years to reach sexual maturity, have the longest gestation period of any land animal at 22 months, and require vast amounts of space and food. A successful breeding program would take centuries just to produce enough generations for genetic change, though some researchers arguetthat process may already be subtly underway with captive elephant populations in Myanmar and Thailand. The larger question beneath these candidates is why humans keep domesticating animals at all.
Beyond food, labor, and companionship, domestication represents one of the most profound relationships between species, a true evolutionary partnership in which both sides are transformed. Wolves became dogs, but humans also changed, becoming better hunters and more skilled at reading social cues, with some researchers suggesting that owning dogs helped humans develop theory of mind, the ability to imagine what another being is thinking. Aurochs became cattle, but the humans who domesticated them built the agricultural foundation that made civilization, cities, writing, and mathematics possible. Therefore, asking which animal comes next is also asking who humans will become as a result.
There is, however, one final candidate that almost nobody discusses, yet may be themost intriguing of all, the wild wolf, though not all wolves, and not most, but specific isolated populations living alongside human settlements for generations. In places where wolves learned to coexist with humans rather than flee or fight, natural selection is already favoring individuals that are less reactive, more curious, and more willing to feed near settlements. This mirrors exactly what likely happened during the original domestication process thousands of yearsago, when bolder, calmer wolves lingered at the edges of human camps, gaining better survival chances generation after generation until one day, a human looked at one and thought, this one can come inside. If thisis true, domestication may not be a one-time ancient event, but a recurring gravitational pull between certain species and human civilizations.
The answer to which animal will be domesticated next may simply be all of them, every one capable, every one ready, because somewhere right now, an animal stands at the edge of a human settlement, looking inside, and not running away.
