* The Polynesian rat (Rattus exulans): This was the most common animal brought by Polynesians. They were a source of food and were also used in some rituals.
* The dog (Canis familiaris): Dogs were brought for hunting and companionship.
* The pig (Sus scrofa): Pigs were a valuable source of food and were also used for religious ceremonies.
It's important to note that the Polynesians didn't bring any domesticated birds to Hawaii. This is likely because they focused on bringing plants that would be useful for their new environment.
The animals they brought had a significant impact on the Hawaiian ecosystem. The Polynesian rat, in particular, caused significant damage to native plants and birds.
Beyond these, there's some debate on whether chickens (Gallus gallus domesticus) were brought by Polynesians or arrived later through European contact.
This limited number of animals brought by Polynesians shows their remarkable ability to adapt to a new environment with limited resources. They focused on establishing a sustainable and thriving agricultural society, prioritizing plant species that would thrive in the Hawaiian climate.
