Age determination is the process of estimating the age of an individual or object. In humans, this can involve examining physical characteristics, dental records, or medical history. For animals, scientists often use methods like analyzing growth rings in bones or teeth. In archaeology, age determination helps date artifacts and fossils. Techniques such as radiocarbon dating and dendrochronology are commonly used to establish the age of organic materials. Accurate age determination is crucial for understanding development, evolution, and historical timelines across various fields, including biology, paleontology, and anthropology.
