Why is "List of extinct indigenous peoples of Brazil" trending?

Wikipedia Overview

At the time of the invasion of Brazil by the Europeans, a total of 2,000 Indigenous nations, divided into several thousand tribes, existed in Brazil. The total number of Native tribes which inhabited present day Brazil at the time of first contact is disputed and difficult to ascertain. The names of large number of tribes who were exterminated as a result of intertribal warfare are not recorded anywhere and so is the case of several smaller tribes who were wiped out by the colonizers. Curt Nimuendajú gives a list of 1,400 nations in his monumental work Mapa etno-histórico do Brasil e regiões adjacentes, but he ignored many smaller (extinct) tribes in Eastern Brazil, and was at the time of writing unaware of some other tribes which were uncontacted at that time. Currently only 200 nations are alive, with no survivors being reported for the remaining nations. However, this doesn't mean their bloodlines are extinct; only their cultures. Brazilian Pardo and Mestizo population have mostly unknown indigenous backgrounds, some or several of them likely stemming from extinct cultures. The Bandeirantes hunted and enslaved indigenous peoples in the then unexplored interior of Brazil from the 16th to the early 19th century. The indigenous peoples were eventually acculturated and integrated into European civilization.
