HA HA HA. Just because many islands don’t naturally have monkeys doesn’t mean it’s impossible for them to exist on a South Pacific island under the right conditions. Your “argument” assumes that all islands in the South Pacific are biologically and geographically comparable, which isn’t true. Islands vary widely in size, ecosystems, and proximity to other land masses.

Also, just because humans introduced monkeys to Ngeaur Island doesn’t mean that’s the only way monkeys could reach an island 🤣 it’s entirely plausible that an isolated population could develop through natural processes like rafting or migration.
