Why do some animals have opposable thumbs?

Opposable thumbs enable animals to grasp and manipulate objects, providing a significant evolutionary advantage. Primates, such as humans and chimpanzees, use their thumbs for tasks like climbing, tool-making, and handling food. This adaptation increases their ability to interact with their environment and improves survival rates. Other animals, like pandas, have a pseudo-thumb that helps them grasp bamboo for eating. The presence of opposable thumbs highlights the role of physical adaptations in shaping behaviours and ecological success.
