How would you translate the following into a "If..Then.." statement?

"The only Australian placentals that could be native to Australia would be animals whose ancestors could not have reached Australia from elsewhere."

I'm thinking that it would be

IF the Australian placental is native to Australia THEN its ancestors could not have reached Australia from elsewhere

Thanks

that's exactly right

Yes - "only", "only if", and "only when" are necessary condition indicators, but "the only" is a sufficient condition indicator.

The English language is just annoying like that sometimes.
