Final answer:
The absence of African Americans with tribal scars in America can be attributed to historical factors such as slavery, social hierarchy, and racism.
Step-by-step explanation:
The absence of African Americans with tribal scars in America can be attributed to a combination of historical factors. Firstly, during the time of slavery, African Americans were often forcibly taken from their homelands in Africa and transported to the Americas as slaves. As a result, they were disconnected from their tribal customs and traditions, including the practice of tribal scarification. Secondly, the social hierarchy and racial dynamics in America at that time made it difficult for African Americans to maintain their cultural heritage. They were subjected to oppression, discrimination, and violence, which further separated them from their indigenous African roots. Finally, the legacy of racism and systematic oppression continued to affect African Americans even after slavery was abolished, resulting in the loss of direct cultural connections.
