Final answer:
Biological determinism, the belief that inequities exist due to innate biological characteristics, is no longer accepted as a theory. Research has shown that any differences between groups are more about nurture than nature, and cannot be used to justify oppression.
Step-by-step explanation:
The idea that inequities exist due to innate biological characteristics, known as biological determinism, is no longer accepted as a theory. It suggests that there are no inherent differences between groups that justify oppression. This belief was based on pseudoscience and has been debunked by research. For example, the notion that race determines intelligence has been refuted by evidence showing that intelligence gaps can be narrowed through access to education.
