Just wondering if anyone can shed some light on the scientific reasons behind why land tortoises do not exist in Australia?
Because God didn't put any there !
And not enough grass in the dry season !

Could Australia have broken away before tortoises evolved? Just a guess
i believe they did inhabit the land mass of Australia before separation but when geographic isolation of Australia took place and marsupials in Australia evolved the tortoises vanished same as the marsupials vanished from other continents as the other mammals evolved.... i believe the tortoises don't exist now in Australia same way as Australian marsupials aren't found anywhere in the other parts of the world... i believe it happened due to geographic isolation... that's what i studied in my school
