Wallace Line to the west of the Philippines. Wallace's studies in Indonesia demonstrated the emerging theory of evolution, at about the same time as Joseph Dalton Hooker and Asa Gray published essays also supporting Darwin's hypothesis. Understanding of the biogeography of the region centers on the relationship of ancient sea levels to the continental shelves. Wallace's Line is visible geographically when the continental shelf contours are examined; it can be seen as a deep-water channel that marks the southeastern edge of the Sunda Shelf which links Borneo, Bali, Java, and Sumatra underwater to the mainland of southeastern Asia. Australia is likewise connected
Belfast–Newry line with a passenger foot crossing adjacent at Sunnymede Park. After passing over the Kingsway, Derriaghy halt is reached, and shortly thereafter, Lambeg and, the final intermediate halt on this section, Hilden. Entering Lisburn city proper, the line skirts Wallace Park before arriving at Lisburn railway station itself. A small yard exists at Lisburn station, typically used by permanent way vehicles and, until recently, the storage of redundant stock. Lisburn is also the junction for the single-track Antrim branch, which runs adjacent to the double-track Newry line through the Lisburn suburbs, creating the illusion of triple-track. These lines pass under Thiepval
