... Although still received with caution by part of the archaeological community, it is interesting to examine the way in which the discussion on possible Pleistocene marine dispersals has evolved, as well as the multitude of approaches (Runnels, Early Palaeolithic on the Greek islands?, 2014; Phoca-Cosmetatou, Rabett, Galanidou, Broodbank, Runnels, & Leppard, 2014;Howitt-Marshall & Runnels, 2016;Papoulia, 2017) It was the lithic finds from Loutro (Mortensen, 2008), Gavdos (Kopaka & Matzanas, 2009), and the Plakias region (Strasser et al. 2010) that provided documentation for human presence on and off the south coast of Crete, subsequently leading to the suggestion for seafaring in the Mediterranean during the Palaeolithic (Strasser, et al., 2010;Strasser, et al., 2011;Kopaka & Matzanas, 2011). Human habitation on insular settings possibly dating to the Middle Palaeolithic was later documented in more sites on Crete (Runnels, McCoy, Bauslaugh, & Murray, 2014) and other parts of the Aegean-Alonissos, Ayios Petros, Ai Stratis, Milos, Naxos, as well as in the Ionian (Ferentinos, Gkioni, Geraga, & Papatheodorou, 2012;Galanidou, 2018). The main problem behind the controversial theories of Pleistocene sea-crossings in the Aegean lies on poor knowledge of prehistoric coastline geography-although important research on this topic has been published for some regions (Sakellariou & Galanidou, 2016), and the insecure chronological context of the scarce Palaeolithic finds from most, if not all, islands. ...
