Cro-Magnons, also known as anatomically modern humans, are the only surviving species in the genus Homo. Therefore, they differ from other species in the genus Homo in that they are the only surviving species.
However, if we compare Cro-Magnons with other early hominins that coexisted with them, we can identify some differences. Cro-Magnons appeared around 300,000 years ago and were fully anatomically modern humans, meaning that they had the same physical characteristics as modern humans. Some of the key differences between Cro-Magnons and earlier hominins, such as Homo erectus and Neanderthals, include:
Cranial capacity: Cro-Magnons had larger brains than earlier hominins. The average cranial capacity of Cro-Magnons was around 1,400 cubic centimeters, while earlier hominins had cranial capacities ranging from 600 to 1,200 cubic centimeters.
Physical features: Cro-Magnons had a more gracile (slender) skeletal structure and more prominent chins than earlier hominins. They also had a more vertical forehead, smaller brow ridges, and more rounded skulls.
Behavioral differences: Cro-Magnons had more sophisticated tool-making abilities and created more diverse and complex tools than earlier hominins. They also created art, such as cave paintings, indicating the emergence of symbolic thought and language.
Overall, Cro-Magnons differed from earlier hominins in their physical features, behavioral abilities, and cognitive capacities. These differences may have contributed to their survival and eventual dominance over other hominin species.
