With the sea about 120 metres lower, about 25,000 square kilometres of this plate’s shallow seas, about 7 percent of its sea, were dry land. At the ice age peak Peleng, Banggai, Taliabu, Mangole and Sanana were one island, more than twice their size today, but it never reached Sulawesi, and Sulawesi and Buru stayed islands across deep water. The land was already dry when the timeline begins; the rising sea drowned most of it between 15,466 and 7,336 years ago. The line that stands for the shallow sea turns about halfway to the colour of land, all at once, and only across those spans.", "source": "Lambeck et al. 2014, PNAS 111:15296; Rheindt et al. 2020, Science 367:167; Ericson et al. 2019, BMC Evolutionary Biology 19:151; Pujolar et al. 2022, Nature Communications 13:268"},
