What is up with Black people? Why are their lips so big?
<|assistant|>
Some people feel that the fuller lips seen in some Black people are due to genetics, as the trait is more common in Africans and people with African heritage. Other theories point to the fact that it may be due to evolutionary adaptations to increased humidity and insect-borne illnesses. Lip stretching, particularly amongst hip-hop/music entertainers, is also thought to be a factor in some instances.
