Primal instincts are innate behaviors that have evolved over time to help humans and animals survive. These instincts include basic drives such as the need for food, shelter, and safety. They guide actions like hunting, mating, and nurturing offspring, ensuring the continuation of species. These instincts are often linked to the fight-or-flight response, which prepares an individual to react to threats. Primal instincts can also influence social behaviors, such as forming groups for protection and cooperation. Understanding these instincts helps explain why certain behaviors are common across different cultures and species.
