Final answer:
Humans and NHAs have different maxilla shapes, with humans having a relatively flat maxilla and NHAs having a protruding maxilla. Maxilla shape is related to anatomical differences and is not influenced by age, social media usage, or shoe size.
Step-by-step explanation:
The maxilla in humans and non-human apes (NHAs) have different shapes. Humans have a relatively flat maxilla, while NHAs such as chimpanzees have a protruding maxilla. The maxilla in humans forms the upper jaw and contains the upper teeth, while in NHAs it serves a different function.
Small jaws and teeth are characteristic of both humans and NHAs. Third molars, also known as wisdom teeth, are larger than other molars and are found in australopithecines and some early Homo species. Additionally, both humans and NHAs have skull shapes resembling H. erectus or H. habilis, including a sagittal keel, which is a small raised ridge on top of the skull.
While maxilla shape is related to anatomical differences between humans and NHAs, it is not influenced by age, social media usage, or shoe size.
