VANUATU: Oceania was the last region on Earth colonized by humans. When the first settlers from the Lapita Culture arrived in Vanuatu 3,000 years ago, they transported certain plants with them that aided their ability to survive, including the banana. Analysis of microparticles trapped in the dental plaque of individuals buried on Efate Island has indicated the presence of the nonnative species at this early date. Banana plants would not only have provided sustenance, but could also have been used for building material, textiles, cordage, and medicine.
