Intelligence is a mechanism for problem-solving, encompassing gathering information, learning, creativity, and critical thinking. It involves a flexible set of skills like information gathering, memory, creativity, and planning, allowing creatures to adapt and survive in various environments.

Humans take pride in various achievements, from particle accelerators to poetry and Pokémon, all made possible by the highly valued trait of intelligence. Defining intelligence proves challenging, as it encompasses problem-solving mechanisms crucial for survival, involving gathering information, memory retention, and learning.

Animals exhibit remarkable problem-solving abilities, memorization skills, and creativity, as demonstrated by raccoons opening complex locks and a raccoon finding a unique solution to obtain a treat. Planning, creativity, and tool usage are key aspects of animal intelligence, as seen in squirrels storing food strategically and primates using tools for hunting.
