@Alligatorob -
I had no idea; never heard it before. And yeah, according to the website,
Outforia:
"The monkey colonies of Florida most likely started in very similar ways to other invasive species. Lab subjects, zoo animals, and escaped pets (registered and unregistered) are the main contributors to invasive species in Florida.
"Florida Atlantic University has been able to genetically track a group of wild vervet monkeys near the Fort Lauderdale-Hollywood International Airport to the Dania Chimpanzee Farm in 1948. How they escaped from the research facility is unsure, but the group has lived in a small mangrove forest for over 70 years."
