Some orangutan populations show distinct tool traditions that neighboring groups do not practice.
Field researchers in Borneo have documented Bornean orangutans deliberately modifying leaves for practical use. Individuals have been observed holding folded leaves as gloves to grasp spiny fruits and branches. Others position broad leaves over their heads during heavy tropical rain, functioning as makeshift umbrellas. These behaviors are not random but repeated actions showing intentional tool use. Orangutans also use sticks to extract seeds and insects from tree cavities. Such flexible problem-solving demonstrates advanced cognitive capacity among great apes. Tool behaviors can vary between regions, suggesting localized cultural traditions.

Using foliage as protective equipment challenges the stereotype that advanced tool use is uniquely human. In dense rainforest environments where spines, insects, and storms are daily hazards, these innovations provide immediate survival advantages. Cultural transmission means juveniles learn by watching their mothers, embedding these skills across generations. However, when populations become isolated by logging roads, cultural knowledge may not spread between groups. The fragmentation of habitat therefore fragments behavior as well.
Tool use in orangutans provides insight into the evolutionary roots of human technology. As one of our closest living relatives, their innovations illuminate cognitive pathways that preceded modern engineering. Yet despite their intelligence, they face threats from agricultural expansion and illegal trade. The disappearance of tool-using populations would erase not just individuals but entire behavioral repertoires evolved over millennia. Conservation thus preserves both biological diversity and cultural intelligence in the wild.
