How many types of early man are believed to have lived in the Bronze Age?

During the Bronze Age, which began around 3300 BCE, several types of early humans were present, primarily Homo sapiens. This period saw the development of advanced societies, but earlier hominins like Neanderthals and Homo erectus had largely disappeared by then. The main focus is on Homo sapiens as they were the dominant species, utilizing bronze tools and engaging in complex social structures.
