The Pleistocene epoch is a geological period that lasted from about 2.6 million to 11,700 years ago, marked by repeated glacial cycles and significant changes in climate and habitat. This epoch is crucial for understanding the evolution of primates, particularly early hominins, as they adapted to shifting environments and developed essential survival skills. The innovations in tool-making and social structures during this time laid the groundwork for the emergence of more advanced species, including Homo habilis, Homo ergaster, and Homo erectus.
