Final answer:
In traditional Maori culture, symbols such as spear heads, waves, and human faces on moko often symbolize ancestry, while the representation of birds does not typically refer to ancestors.
Step-by-step explanation:
The symbols found on a Maori man's chest, known as moko, often have deep cultural significance and can represent various aspects such as ancestry, social status, and personal history. In traditional Maori culture, the symbols such as spear heads, waves, and human faces are commonly used to symbolize ancestry or connections to the tribal history. However, the symbol of birds does not typically refer to ancestors; instead, it might represent other aspects such as spirituality or characteristics attributed to the bird. It's important to recognize that Maori tattooing—or Ta Moko—uses abstract forms inspired by nature, but they are intended to convey personal stories and tribal affiliations rather than depicting clear images.
