Final answer:
Archaic Homo sapiens are distinct from Homo erectus and modern humans due to their physical and cultural features. They have a brain size similar to modern humans but have a thick skull, prominent supraorbital ridges, and lack a prominent chin. They are also viewed as transitional between Homo erectus and Homo sapiens and may have been the first species to use language.
Step-by-step explanation:
Archaic Homo sapiens are distinct from Homo erectus and modern humans due to their physical and cultural features. Physically, archaic Homo sapiens have a brain size similar to modern humans, but they have a thick skull, prominent supraorbital ridges, and lack a prominent chin.
