Although it seems that some animals are completely extinct, there are still some animals that are still alive, just living in invisible places. This is more than you think. Some animals have been deliberately wiped out or extinct by humans, but they are still alive, sometimes even as part of a large healthy population, completely unaware of their so-called extinction. This is what biologists call the Lazarus taxa. They are thought to have died and then “brought back to life” by new discoveries.
Today we are going to talk about Chacoan Peccaries
There is a long history of Western scientists exploring new regions and not believing local accounts of wildlife. Sometimes it’s for a good reason. The Congo river dinosaur Mokele-mbembe is not real. But sometimes, that causes researchers to miss huge discoveries. The okapi, Komodo dragon, and mountain gorilla are all very real fauna whose existence was attested to by locals and yet went undiscovered by modern scientists for decades.
The Chacoan peccary is another example. Fossil evidence of its existence was found in 1930 in Argentina, and without living examples, scientists assumed it an extinct species. Native Argentinians, however, insisted they had seen the pigs many times over the years, so they must still be alive. Their claims were ignored until 1971, when scientists found living specimens- an entire family unit, in fact. Sadly, since its discovery, the widespread deforestation of South America has threatened to turn its extinction from fiction to fact.
