from your link:Cautious hope...some sort of co-existence possible.
https://www.abc.net.au/news/2023-09...s-hope-deadly-facial-tumour-disease/102800670
"... the wildlife biologist has watched the population decline to less than 40 per cent of what it was, because of the contagious cancer.
He's also watched, stunned, as both tumour and animal have "somehow" evolved at incredible speed to co-exist.
"In the past we have observed genetic adaptations in the devil, which have allowed them to persist despite the deadly cancer", he said.
"Now we have evidence that, through natural selection, the tumour is fine tuning its optimal virulence, a trade-off between transmission rate and disease-induced mortality".
"This means that DFTD is very unlikely to drive the devil to extinction, but it also means the disease will not disappear, it's an evolutionary deal between the two to coexist with each other.""

I don't know who put that 'somehow' there or why. Its completely un-necessary, and I'm glad someone has thought to highlight it.
This simple natural selection playing out. A catastrophic decline followed by an arms race that 'seeks' maximisation of the host's health (measured by successful creation of offspring) while maintaining a foothold. The endgame will be the elimination of the virus.
