Genetic Revelations on small wild cats in Brazil went as expected...

                        Apologies for not circling the individual with a red circle and yellow arrow

According to National Geographic --

"Eizirik and colleagues obtained DNA samples from a total of 216 different Leopardus cats across their ranges. Analysis of the DNA sequences found in the mitochondria, the cell’s power plant, revealed ancient interbreeding between the Pampas cat and the northeastern tigrina.
Since an individual only inherits mitochondrial DNA from its mother, researchers could peer into the ancient history of these two felines, and found that they mated together frequently before the two cats split into separate species.
Although the Geoffroy’s cat and the southern tigrina divided into separate species over a million years ago, they began to mate together in the more recent past in the areas of southern Brazil and Bolivia where their habitats overlap. While the two cats interbreed regularly at this contact zone, the mating doesn’t extend to farther areas and the two species remain distinct."
