I want to know the answer to the following question:
What indigenous population is now virtually extinct?
All the background I'm provided with is that "In 2005, Argentina's indigenous population (known as pueblos originarios) numbered about 600,329 (1.6% of total population); this figure includes 457,363 people who self-identified as belonging to an indigenous ethnic group and 142,966 who identified themselves as first-generation descendants of an indigenous people.". Is that enough to answer the question?
Answer: no
