With the sea about 120 metres lower, about 34,000 square kilometres of this plate’s shallow seas were dry land. Buton, Muna, Wawonii and Kabaena were joined to Sulawesi, Ambon and Boano to Seram, and the two Kai islands became one, more than three times their size today. But deep water still parted every island from Asia and from New Guinea. The land was already dry when the timeline begins; the rising sea drowned most of it between 14,386 and 6,826 years ago. The lines that stand for the sea turn part of the way to the colour of land, all at once, and only across those spans.", "source": "Lambeck et al. 2014, PNAS 111:15296; Bird et al. 2019, Scientific Reports 9:8220; Ó Marcaigh et al. 2021, Zoologischer Anzeiger 293:314"},
