Prehistoric studies focus on the period of human history before written records, which spans millions of years. This field examines artifacts, fossils, and other evidence to understand early human life, cultures, and environments. Researchers often study tools, cave paintings, and remains of ancient animals to piece together how prehistoric people lived and interacted with their surroundings. Key methods in prehistoric studies include archaeology and paleontology. Archaeologists excavate sites to uncover artifacts, while paleontologists study fossils to learn about extinct species. Important discoveries, such as the Stonehenge monument and Neanderthal remains, provide valuable insights into the lives of our ancient ancestors.
