<human>:  What is the origin of biracial identity?
<bot>: The origin of biracial identity is largely rooted in the history of colonialism, slavery and segregation practices around the world. In countries where populations of different racial backgrounds intermingled, a new mixed-race identity emerged, which often denotes the combination of two distinct identities. This mixed-race identity is sometimes referred to as multiracial, biracial, bi-ethnic, blended or blended-race.
