It is stated in your text that Blumenbach introduced hierarchies in human groups with notions of superiority (the idea being, "this race is better than that race").How are these notions still embedded in common, everyday usage of racial identities, either in the United States or abroad?​

The notions of racial superiority introduced by Blumenbach are still embedded in common, everyday usage of racial identities in various ways. In the United States, for example, racial stereotypes and prejudices continue to shape how different racial groups are perceived and treated. This can be seen in the way certain racial groups are disproportionately targeted by law enforcement, or in the way media representations often reinforce negative stereotypes about certain races.

Abroad, similar notions of racial superiority can be seen in the way certain racial groups are marginalized or discriminated against in various societies. This can manifest in policies that limit the rights and opportunities of certain racial groups, or in the way certain racial groups are portrayed in the media and popular culture.

Overall, the hierarchical notions of racial superiority introduced by Blumenbach continue to influence how different racial groups are perceived and treated in both the United States and abroad, shaping everyday interactions and societal structures. It is important to recognize and challenge these ingrained biases in order to work towards a more equitable and just society.
