During his second survey expedition, the naturalist noted it as \u201ca large wolf-like fox\u201d. It was the only native land mammal on the entire archipelago.<\/p>\n<p>But today, in a discovery that is said to have huge implications for conservationists, research has unveiled that the animal was actually the final population of a South American fox that once lived alongside humans.\u00a0<\/p>\n<p>A new study, conducted by conservation charity <a href=\"https:\/\/www.zsl.org\/news-and-events\/news\/falkland-islands-were-final-stronghold-domesticated-fox-species\" rel=\"nofollow noopener\" target=\"_blank\">ZSL, the Zoological Society of London<\/a>, reveals that the supposed wolf was not a separate species, but in fact was the final surviving remnant population of the South American fox \u2013 an animal that lived on the remote Atlantic islands for another 250 years after its disappearance from mainland South America.\u00a0<\/p>\n<p>Archaeological evidence suggests the foxes were once kept as pets by hunter-gatherers in South America, long before domesticated dogs were brought to the region.\u00a0<\/p>\n<p>Darwin noted how the Falkland Islands wolf was easily approached and hunted by settlers, and by 1876 it had been completely wiped out due to persecution and demand for its fur.\u00a0<\/p>\n<p><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/animal-facts\/mammals\/can-dogs-and-foxes-interbreed\" rel=\"nofollow noopener\" target=\"_blank\">Can dogs and foxes interbreed?<\/a><br \/><a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/animal-facts\/mammals\/what-is-the-biggest-wolf\" rel=\"nofollow noopener\" target=\"_blank\">What is the biggest wolf in the world?

D. avus was believed to have gone extinct at least 400 years ago. But the new paper, published in the Biological Journal of the Linnean Society, reassesses the data to reveal otherwise.\u00a0\u00a0<\/p>\n<p>The finding gives a new perspective on human-caused extinctions, and helps conservationists predict the impact of human activities on wildlife across the globe.\u00a0<\/p>\n<p><img loading=\"lazy\" width=\"1719\" height=\"1123\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2025\/09\/Drawing-of-Falklands-Island-Wolf-at-the-time-called-Canis-Antarticus-The-Antartic-Wolf-by-J.G-Keulem.webp\" alt=\"Drawing of Falklands Island Wolf\" class=\"wp-image-141444\"\/>A drawing of the Falklands Islands wolf, at the time named Canis Antarticus, The Antartic Wolf, by J G Keulemans. Credit: ZSL Library<\/p>\n<p>Professor Samuel Turvey, lead author and researcher at ZSL\u2019s Institute of Zoology, explained: \u201cWhen settlers from Europe first landed on the shores of the Falklands, they were met by a strangely tame, tawny-coloured wolf-like creature \u2013 about the size of a small labrador. The naivety that ultimately led to its extinction has traditionally been blamed on the wolf\u2019s isolation.\u00a0\u00a0<\/p>\n<p>\u201cJust like the famous dodo, it was thought that millennia of evolution sheltered from the fear of any natural predators, which resulted in a creature that was completely unafraid of people. But the reality was more complicated \u2013 and more tragic. The friendliness that made this canine an easy target for hunters was not due to a lack of contact with humans, but because they once lived alongside us.\u00a0<\/p>\n<p>\u201cThis isn\u2019t just a heartbreaking twist to an already tragic story. The finding fundamentally shifts our understanding of what drove this species to go extinct \u2013 and has wider implications for our knowledge of human-caused extinctions today.\u201d\u00a0\u00a0<\/p>\n<p>Archaeologists have uncovered D. avus skeletons buried in prehistoric human graves in South America, and analysis of one suggests the fox shared meals with ancient hunter-gatherers \u2013 strong evidence they were once kept as pets. Other recent discoveries also point to human presence on the Falkland Islands well before Europeans arrived in the 1600s, suggesting that early settlers from South America may have brought these foxes with them.<\/p>\n<p>Turvey went on to explain: \u201cSixteen thousand years is like the blink of an eye on an evolutionary timescale. It\u2019s comparable to when many British mammals separated from populations of the same species on mainland Europe. New analysis even indicates that D. avus and the Falkland Islands wolf could successfully breed \u2013 all of which adds up to suggest the wolves Darwin met were the last survivors of a fox thought to have vanished centuries earlier.\u00a0<\/p>\n<p>\u201cThis means only one member of the fox, wolf and dog family has been driven to extinction by humans since the end of the Ice Age, advancing our understanding of how many unique species we have already lost.\u201d\u00a0<\/p>\n<p>The team behind the paper suggest D. avus should be renamed to the scientific name for the Falkland Islands wolf &#8211; Dusicyon australis.\u00a0<\/p>\n<p>Realising that D. avus and the Falkland Islands wolf are actually the same species doesn\u2019t just change the story of their extinction \u2013 it also offers valuable insights for today\u2019s conservation efforts, helping scientists better understand how human activity impacts wildlife over time.<\/p>\n<p>The finding that the Falkland Islands wolf was introduced to the islands also raises the question of how its arrival impacted the historical ecosystems of the islands \u2013 and how that has impacted the region\u2019s biodiversity centuries later.\u00a0<\/p>\n<p>Samuel said: \u201cWe can\u2019t bring the Falkland Islands wolf back, but its story helps us save the wildlife still with us today. By refining our baseline for assessing the vulnerability of species to extinction, this finding allows us to become even better at predicting how threatened species respond to human pressures, and how to plan conservation action as effectively as possible.\u201d<\/p>\n<p>Main image: Drawing of the Falkland Islands wolf by George Waterhouse in Mammal Volume of The Zoology of the Voyage of the H.M.S Beagle.
