Hominin research focuses on the study of human ancestors, including extinct species that are closely related to humans. This includes hominins such as Homo habilis, Homo erectus, Neanderthals, and others. Researchers in this field use a variety of methods, including fossil analysis, genetic studies, and archaeological evidence, to better understand the evolutionary history and behavior of these early human ancestors. By studying hominins, researchers gain insights into the origins of human traits, behaviors, and adaptations over millions of years.
