Humans take immense pride in their achievements, from the marvels of particle accelerators to the creativity of poetry and the cultural phenomenon of Pokémon. These accomplishments are possible due to a trait we hold in high regard: intelligence. However, defining intelligence is not straightforward. While we often compare it to traits like height or strength, its true nature is complex and multifaceted.
At its core, intelligence is a mechanism for solving problems, particularly those related to survival, such as finding food, securing shelter, and evading predators. It encompasses a range of abilities, including knowledge acquisition, learning, creativity, strategic thinking, and critical analysis. These capabilities manifest in diverse behaviors, from instinctual reactions to advanced learning and awareness. However, scientists continue to debate where intelligence begins and what should be classified as intelligent behavior.
Intelligence can be viewed as a flexible set of skills or a toolbox. The most fundamental tools include the ability to gather, store, and utilize information. Sensory input—vision, sound, smell, touch, and taste—helps organisms navigate and respond to their environment. Additionally, monitoring internal states like hunger and fatigue is crucial for survival.
Memory, the second tool, allows living beings to save and recall information, preventing them from starting anew with each encounter. Memories can encompass events, places, associations, and behaviors, such as hunting or foraging techniques. Learning, the process of forming repeatable and adaptable sequences of thoughts or actions, is essential for mastering these behaviors.
Even seemingly simple organisms can exhibit intelligent behaviors. For instance, the acellular slime mold, a single large cell, demonstrates problem-solving abilities akin to those of animals with simple brains. When placed in a maze with food, it marks its path with slime trails, avoiding dead-ends and efficiently reaching its goal. While this behavior is hardwired, it provides the slime mold with a survival advantage.
Bees showcase more adaptive intelligence. In experiments, bumblebees were trained to move a colored ball into a goal for a sugar reward. Over time, they became more efficient, choosing the closest ball to the goal, regardless of color. This adaptability highlights their problem-solving skills.
More complex animals possess a broader range of problem-solving abilities, which we can term the “Library of Knowledge.” Raccoons, for example, are adept at obtaining human food through a combination of theoretical and practical skills. In studies, they quickly learned to open boxes with various locks, remembering these skills even a year later.
Creativity, another impressive tool, involves generating new and valuable solutions by connecting seemingly unrelated elements. In one study, raccoons were shown how to raise water levels in a tank to reach a marshmallow by dropping pebbles. One raccoon ingeniously tipped the tub over, demonstrating creative problem-solving.
Planning, an advanced dimension of problem-solving, involves organizing activities to achieve a desired goal. Squirrels, for instance, instinctively hoard food but use advanced thinking to make strategic decisions. They assess each nut’s value and effort required for storage, even creating fake caches to deceive potential thieves.
Different animals possess unique skills suited to their lifestyles. Squirrels, as territorial omnivores, benefit from memory and deception, while sheep, as social grazers, excel in recognizing individuals. Humans, however, have developed an exceptionally diverse intelligence toolkit, augmented by culture.
Human intelligence is unique due to our ability to collaborate and share knowledge across generations. This cultural aspect enables us to tackle challenges beyond individual capabilities, such as building space rockets or particle accelerators. However, it also presents new problems, including climate change and antibiotic resistance, which require long-term solutions.
Our intelligence toolbox is vast, and by leveraging it, we can address these complex issues. In education, tools like infographic posters aid learning, and new educational resources continue to expand our understanding of the world.

Use a large sheet of paper or a digital tool to create a mind map that explores the different facets of intelligence discussed in the article. Include branches for problem-solving, memory, learning, creativity, and strategic thinking. Add examples from nature and human culture to illustrate each concept.
Design a simple experiment to test problem-solving skills in humans or animals. Consider using puzzles or mazes. Document your hypothesis, method, and expected outcomes. If possible, conduct the experiment and analyze the results, comparing them to examples from the article.
Choose an animal mentioned in the article, such as raccoons or bees, and research their problem-solving abilities. Prepare a presentation that includes videos or images to demonstrate their intelligence. Discuss how these abilities compare to human intelligence.
Participate in a class debate on whether intelligence is more influenced by genetic factors (nature) or environmental factors (nurture). Use examples from the article and additional research to support your arguments. Consider the role of culture in human intelligence.
Design an infographic that visually represents the “intelligence toolbox” described in the article. Include sections for sensory input, memory, learning, creativity, and strategic thinking. Use graphics and concise text to make the information engaging and easy to understand.
