[6] Study of Chono bones reveal they were prone to suffer joint problems, infectious diseases and in some cases traumatic injuries.

[7] Scholar Alberto Trivera considers that there is no continuity between the human culture seen in the archaeological site of Monte Verde and any historical group.

[8] According to archaeologist Ricardo E. Latcham the Chono people along other sea-faring nomads may be remnants from more widespread indigenous groups that were pushed south by "successive invasions" from more northern tribes.

[10] This has led to the assumption that the Chono were the people who left behind most of the abundant shell middens (Spanish: conchales) of Chiloé Archipelago, yet this claim is unverified.

[11] A theory postulated by chronicler José Pérez García holds the Cuncos settled in Chiloé Island in pre-Hispanic times as a consequence of a push from more northern Huilliches who in turn were being displaced by the Mapuche.

[17][18] These incursions turned into outright slave raids following the 1608 decree of King Philip III of Spain that legalized slavery of "indigenous rebels".

[18] The Chono people were not the only ones to suffer from the slave raids organized by the Spanish from Chiloé; so did also the Huilliche of Valdivia, Osorno, and indigenous groups from Nahuel Huapi Lake across the Andes.

[18] Some Chono slaves may have been exported north to the Spanish settlements of Central Chile[19] which was becoming a melting pot for uprooted indigenous peoples.

[22] As a result of a corsair and pirate menace the Spanish authorities were ordered to depopulate the archipelagos of Chono and Guaiteca to deprive their enemies of any eventual support from the native populations.

[11] This then led to the transfer of population to Chiloé Archipelago in the north while some Chono moved south of Taitao Peninsula, effectively depopulating the territory.

[25] In the 1740s Martín Olleta was able to understand the importance of the wreckage of HMS Wager and profited from it by handing over the survivors to the Spanish authorities while keeping valuable metal objects obtained from the wreck.

[3] Writer Benjamín Subercaseaux visited Taitao Peninsula in 1946 reporting having seen footsteps and fresh human feces he thought indicated that nomadic Chono, as known from the historical record, still existed.

[28] Historian Rodolfo Urbina Burgos follows up on this thought and argues the Chono as a whole went extinct as a distinctive group because of a chronic shortage of women.
