Final answer:
Neanderthals were robust and adept hominins who lived between 200,000 to 40,000 years ago. They produced advanced stone tools, buried their dead, and cared for each other, suggesting a complex social structure. The correct answer is option a., b., c. and f.
Step-by-step explanation:
The Neanderthals, members of the genus Homo who evolved from Homo erectus, were a distinct type of hominins that lived in Europe and western Asia from about 200,000 to 40,000 years ago. Known for being tough and strong, Neanderthals were physically larger and stronger than their counterparts, Homo Sapiens Sapiens. They were adept at making stone tools; their technology is referred to as the Mousterian tool industry, characterized by flake tools which they struck from cores.
Neanderthals also buried their dead on at least some occasions, as evidenced by archaeological sites like the Shanidar Cave in Iraq. While there is no definitive evidence of cannibalism, like modern humans, they occasionally suffered from injuries, likely due to their hunting lifestyle. Importantly, Neanderthals demonstrated a care for one another, which is evidenced by skeletons with healed injuries, suggesting that they looked after the sick and injured within their groups.
