Survival instincts are innate behaviors that help organisms respond to threats and challenges in their environment. These instincts are crucial for the survival of species, enabling them to react quickly to danger, find food, and reproduce. Common examples include the fight-or-flight response, which prepares the body to either confront or escape from a threat. In humans, survival instincts can manifest as heightened awareness in dangerous situations or a strong desire to protect loved ones. These instincts are influenced by both genetics and experiences, shaping how individuals respond to stress and adversity throughout their lives.
