What is one characteristic of hominids?

Hominids are distinguished by several key characteristics, one of which is the possession of large and complex brains. This trait is significant as it is closely linked to increased cognitive abilities, such as problem-solving, abstract thinking, and social interaction. The development of a larger brain has allowed hominids to create complex social structures, use sophisticated tools, and communicate in more nuanced ways.

In contrast, while some hominids may have herbivorous diets, they are not exclusively plant eaters, which rules out the first option. Living in isolation is also not a typical characteristic, as hominids are generally known for their social behaviors and interactions with others in their species. Moreover, although vocal communication is present in many hominids, not all hominid species exhibit vocal communication to the same extent or complexity. Thus, having large complex brains stands out as a defining feature that significantly impacts behavior and survival.
