Human characteristics, or traits, refer to the distinguishing qualities or features that define individuals. These traits can be physical, such as height, eye color, and hair type, or they can be psychological, including personality aspects like kindness, honesty, and resilience. Traits are influenced by genetics, environment, and personal experiences. Additionally, human traits can be categorized into two main types: inherited and acquired. Inherited traits are passed down from parents to offspring through genes, while acquired traits develop through life experiences and learning. Understanding these characteristics helps in studying human behavior and interactions within society.
