Final answer:
The human remains found at Gran Dolina are attributed to Homo antecessor, not Homo erectus, marking the statement as false. The discovery of Homo naledi was significant as it presented a new species with unique features and behaviors, potentially indicating intentional burial practices.
Step-by-step explanation:
The statement that The Gran Dolina human remains are definitely Homo Erectus is false. The human remains found at Gran Dolina, part of the Atapuerca site in Spain, are actually attributed to a different species known as Homo antecessor, which is believed to be a potential common ancestor to both Homo sapiens (modern humans) and Neanderthals. These remains represent individuals that are on a distinct evolutionary line from Homo erectus, which is another earlier human ancestor. Although Homo erectus was in the same family as modern humans, and is a significant figure in the human evolution narrative, the specific remains at Gran Dolina do not belong to this species.
The discovery of Homo naledi was exciting because it added a new member to our genus Homo. This species exhibited a mixture of primitive features, such as small brains and curved fingers, with humanlike characteristics such as feet and teeth suited to bipedalism. Moreover, the potential for intentional burial practices suggested by the deposit of bones in a remote cave chamber has implications for our understanding of the social behaviors of early human ancestors.
