“…Regarding the lithic points, a similar geographical "jump" also occurs; beyond the Chonos archipelago, they are found in the Strait of Magellan/Otway Sea (Morello et al, 2002;Legoupil, 2003;San Román, 2005) and the Beagle Channel (Orquera et al, 1977) mostly associated with dates close to ~5,000-4000 BP. Some researchers propose that these are technological and subsistence elements used as defense against a second cultural group ("Ponsonby tradition" Legoupil and Pigeot, 2009) that would occupy the inland seas at least between 5,000-4,000 years BP and possibly into the next millennium (Morello et al, 2002;Morello et al, 2004). Technological and temporal similarities with the northern Chiloé/Reloncaví Basin (Díaz and Garreton, 1972;Ocampo and Rivas, 2004;Munita, 2007;Reyes et al, 2020;Munita et al, 2021;Rebolledo et al, 2021;Sierralta et al, 2021) presumed a northern influence that would differ from the earliest contexts of maritime adaptation recorded in the middle Holocene in Fuego-Patagonia (Morello et al, 2015;San Román et al, 2016), defined as the Englefield Culture (between ~6,500 and 5,000 years BP; Emperaire et al, 1961;Ortiz Troncoso, 1975;Legoupil, 1997;San Román, 2005, San Roman, 2010.…”
