The last know two members of a wolf family identified as a male and female of a
Isle Royal, Michigan were examined and tracked by The National Park Service. Christine Mlot quoted a document reporting that the two wolves are in fact "They are father and daughter as well as half siblings, born 2 years apart to the same mother" (Mlot 2016)
The wolves are so deeply inbred that researchers do not believe that population can thrive from the two wolves. researchers said that wolves in general try to avoid inbreeding. However with such a small population in a remote location, its as though other options were thrown out the window.
solutions for this problem were being thrown around for example bringing in new wolves into the gene pool however that was shortly overturned. now solutions are still in process but nothing is set.
opinion.: its a shame how a family of wolves can be erased this easy. i do agree with the solution to bring in new wolves to expand the gene pool, but also taking eggs from the femal and sperm from the male, then mutating the genes and implanting it back into the female hoping for new progeny.
