Final answer:
Archaic Homo sapiens differed from anatomically modern humans in several ways, including a thicker skull, prominent brow ridges, and a lack of a prominent chin.
Step-by-step explanation:
Archaic Homo sapiens differed from anatomically modern humans in several ways. They had a thicker skull, prominent brow ridges, and a lack of a prominent chin. While their brain size overlapped with modern humans, averaging 1,200 to 1,400 cubic centimeters, it is important to note that brain size alone does not determine intelligence. Some researchers believe that archaic Homo may have been the first species to use language, based on the size of their brains.
