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 six regions grouped into Megagaea, Notogaea, and Neogaea. A line between the Aru and Tanimbar Islands, (15[1])named (15[1])for Richard Lydekker, marks the eastern boundary of a region named for this geographer. The most famous feature named for this person has alternate northern extensions proposed by (*) Ernst Mayr and Thomas Huxley (10[1])and passes through the Makassar and Lombok 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■
