Archaeologists have found evidence that as humans entered what we now refer to as the Upper Paleolithic Era, they started using a whole new toolset. The evidence suggests that major behavioral shifts also occurred. For example, humans started making arresting cave paintings and carving statuettes. Scholars refer to these changes as the Upper Paleolithic Revolution. Readers will learn how archaeologists use evidence to piece together what life was like during the Upper Paleolithic Era. Theories about the origins and development of language are also discussed, as are new discoveries about archaic human admixture with modern humans.
