Final answer:
The Dmanisi skull known as the 'old timer' provides evidence of Homo erectus presence and activities during the Lower Paleolithic period.
Step-by-step explanation:
At Dmanisi, the skull known as the 'old timer' (skull D3444) provides evidence for the presence and activities of early human species, Homo erectus, in the Lower Paleolithic period.
The Dmanisi site is significant for our understanding of human evolution and migration patterns, as it represents some of the earliest instances of early hominids outside Africa. Studying skull D3444 and other findings from Dmanisi provides valuable insights into the physical characteristics, behavior, and technology of early human ancestors during the Lower Paleolithic era, which includes evidence of tool use and social behavior.
