'Often evolution works through big changes in single genes,' explains Joel, 'but our findings show that resistance to myxomatosis likely evolved through lots of small effects spread across the genome.'
Crucially, these all occurred in the same genes relating to immunity.
Hopefully, for our pet rabbits in Australia, the genes will continue to evolve until there is complete immunity to the dreaded, incurable rabbit Myxomatosis virus. Symptoms of Myxomatosis are: reddening of both eyes, a pinkness and swelling of nose, ears and anus. The rabbit's ears will be hot. Gradually lesions appear. Finally the eyes will swell shut, the swelling in the rabbit's mouth will stop eating and drinking.
If a rabbit is found with Myxomatosis, it should be taken to a vet for humane euthanasia as there is no treatment and no cure.
