It was hunted to extinction, but lack of genome diversity reduced any chance of survival
"Even if humans hadn’t hunted the Tasmanian tiger to extinction, its low genetic diversity may have naturally doomed the curious marsupial, researchers have found.
"We found that the thylacine had even less genetic diversity than the Tasmanian devil,” study researcher Andrew Pask, of the University of Connecticut, said in a statement. “If they were still be around today, they’d be at a severe risk, just like the devil.” “
The study was published Wednesday in the journal PLoS ONE.
