Southeast Asia Philippines. The eastern half of Indonesia and East Timor (east of the Wallace Line) are considered to be biogeographically part of Oceania (Wallacea) due to its distinctive faunal features. New Guinea and its surrounding islands are geologically considered as a part of Australian continent, connected via the Sahul Shelf. The region was already inhabited by Homo erectus from 1,000,000 years ago during the Middle Pleistocene age. "Homo sapiens" reached the region by around 45,000 years ago, having moved eastwards from the Indian subcontinent. Rock art (parietal art) dating from 40,000 years ago (which is currently the world's oldest) has been
Dwane Wallace After the war, Wallace quickly developed an all-metal replacement of the C-34—the Cessna 190 / Cessna 195, a speedy 6-seat, single-engine, executive aircraft, powered by a large, traditional radial engine. Wallace then guided Cessna away from the pioneering un-braced "cantilever"-wing design concepts of Clyde Cessna, towards more conservative-and-traditional, "strut-braced," high wings—producing the world's most successful line of single-engine light aircraft, ranging through numerous variants from the Cessna 120/Cessna 140 to the Cessna 207—despite the industry's move towards cantilever wings. The 120/140 also was the beginning of Cessna's conversion to smaller-cabin aircraft with streamlined, flat, horizontal-cylinder engines. The 120/140's distinguishing feature,
