Final answer:
Most of the Taíno and Arawak peoples were decimated due to European colonization, and today only sparse populations with Amerindian heritage may remain across the Caribbean.
Step-by-step explanation:
The Taíno and Arawak peoples were the indigenious groups of the Caribbean, notably on islands like Hispaniola, Puerto Rico, and Cuba. Through a combination of warfare, enslavement, and disease brought by European colonizers, their numbers were severely depleted. Today, the majority of people with Amerindian heritage, if any remain, reside sparsely across the Caribbean. However, it is crucial to recognize that due to the devastating impact of these historical events, the Taíno and Arawak cultures as they existed prior to European contact do not exist in the same way today.
