Identifying traits are specific characteristics or features that help distinguish one person, object, or species from another. These traits can be physical, such as color, size, or shape, or behavioral, like habits and preferences. For example, the identifying traits of a golden retriever include its friendly demeanor and golden fur. In biology, identifying traits are crucial for classification and understanding biodiversity. Scientists use these traits to categorize organisms into groups, such as mammals or birds. By studying these characteristics, researchers can learn more about the relationships between different species and their environments.
