 Since bananas do not produce phytoliths in the same quantity and frequency as grass and other plants, researchers have concluded that the abundance of banana phytoliths found in a managed grassed landscape between 6950 and 6550 years ago suggests deliberate planting.The bananas grown at Kuk Swamp were Eumusa bananas, which developed as the most significant and largest group of banana domesticates.This makes Kuk Swamp one of the earliest sites in the world for the development of agriculture.
