Final answer:
The hominid species referred to in the question is Homo heidelbergensis, an archaic human ancestor to modern humans and Neanderthals, which had a robust cranium with two distinct brow ridges and other features more similar to modern humans.
Step-by-step explanation:
The individual described lived between about 600,000 years ago (kya) to about 130,000 years ago, with remains found across Africa, Europe, and Asia and having a particular set of physical skull characteristics. This description matches that of Homo heidelbergensis, an archaic human species that is known to be an ancestor to both modern humans and Neanderthals and lived during the time specified.
Homo heidelbergensis had a long, low skull, large brow ridges, and facial morphology that more closely resembled modern humans compared to their predecessors. They are known from various fossil records such as the Bodo cranium found in Ethiopia, with features like a large cranial capacity of approximately 1,250 cubic centimeters, which is within the range of variation for modern humans. Key attributes distinguishing Homo heidelbergensis from other hominids include robust cranial bones and the presence of two distinct brow ridges, aligning with the features detailed in the question.
