The Siboga expedition of non-sociologist Max Weber proposed a boundary bisecting a region named for this person. This person built on Philip Sclater’s work to posit that the world was split into three broad regions of Megagaea, Notogaea, and Neogaea in The Geographical Distribution of Animals. A line between the Aru and Tanimbar Islands, (15[1])named for Richard Lydekker, marks the eastern boundary of a region named for this geographer. (15[1])The most famous feature named for this person has alternate northern extensions proposed by (*) Ernst Mayr and Thomas Huxley and passes through the Makassar and Lombok (10[1])Straits. The border between land home to Asian fauna and a transitional region towards Australasian fauna, named for this biologist, is his namesake “Line.” For 10 points, name this “father of biogeography” whose discoveries spurred the publication of On the Origin of Species. ■END■
