Natural specimens are samples of materials or organisms that occur in nature. They can include plants, animals, minerals, and fossils, and are often collected for study or display. These specimens help scientists understand biodiversity, ecosystems, and the history of life on Earth. In scientific research, natural specimens are crucial for various fields, such as biology, geology, and paleontology. They provide valuable insights into the characteristics and behaviors of different species, as well as the processes that shape our planet. Collecting and preserving these specimens allows for ongoing study and education about the natural world.
