Expert Solution
Step 1: Thus the answer for above is as follows:-

The Herto man cranium, discovered in the Herto Bouri area of Ethiopia, is a significant archaeological find dating back approximately 160,000 years. This specimen is one of the earliest known fossils representing anatomically modern Homo sapiens. Here are some more details about the Herto man cranium: 

  1. Discovery: The Herto man consists of two adults and one child, and the adult crania were discovered in 1997 by a team led by Ethiopian paleoanthropologist Dr. Berhane Asfaw.

  2. Age and Significance: Believed to be around 160,000 years old, the Herto man is significant because it represents one of the oldest known examples of Homo sapiens fossils. 

  3. Modern Human Traits: Despite displaying some archaic features like a robust brow ridge, the Herto crania show several key characteristics of modern humans, including a large cranial capacity and a flat and broad forehead, reflecting a transition toward the anatomically modern human form. 
  4. Cultural Implications: The discovery of the Herto man suggests that these early humans had complex behaviors and possibly engaged in rituals, as evidenced by cut marks on the bones, implying the possibility of mortuary practices. 

The archaic trait that herto man display is :

• One of the archaic traits evident in this specimen is the robust brow ridge, a feature more commonly associated with earlier human ancestors, such as Homo heidelbergensis or Homo erectus. This prominent brow ridge was useful for protection, providing structural support for the face. 

Robust Brow Ridge: Similar to earlier hominins, the Herto man displays a prominent brow ridge, a feature associated with archaic human ancestors. This ridge served as protection and structural support for the face. 

Flat and Broad Forehead: The cranium exhibits a relatively flat and broad forehead, which is more in line with modern human characteristics, contributing to increased brain capacity.
