Discerning the spatial patterns of biodiversity and understanding its ultimate (why) and proximate (how) causes is very dear to biogeography and is one of the key concepts of macroecology. Some places on earth contain more species than others. All species present in a given space and time either originated (speciation) there or dispersed and arrived from another place and settled there. Biogeographers seek to understand the past and current distributions of species by incorporating historical, evolutionary, and ecological factors. The early biogeographers or “naturalists”, in their sacred quest to serve “the creator”, traveled to various parts of the world and imparted valuable knowledge about the different patterns and processes of nature. Linnaeus (1743), on the one hand, hypothesized that the primordial Earth was filled with water except for the highest mountain peak, namely Mount Ararat, known to be the site of paradise and when the sea level fell the exposed land was colonized by plants. and animals that migrated from the high altitude areas of Mount Ararat while Willdenow (1805) hypothesized that within each geographic region of the earth, plants and animals were first placed and then survived the great flood on many mountain ranges (Lomolino, 2001) . Von Humboldt and Darwin in the South American Andes and the Wallace Islands of Southeast Asia noted the decreasing trend in patterns of species richness at altitude (McCain and Grytnes, 2010). Subsequent work by Grinnell (1917), Whittaker (1952), Terborgh (1977, 1985) on species richness at altitude was accepted and established a well-established pattern for all species for more than two decades (McCain and Grytnes, 2010) . However, current research on elevational gradients is... halfway through the article... mountain regions present a high species diversity due to allopatric and parapatric speciation favored by topographic complexity and climatic zonation (Kozak and Wiens, 2010) . In an attempt to explain2 two hypotheses have been put forward. Mountain Museum Hypothesis: Mountain regions have higher species richness at intermediate levels simply because these elevations have been occupied for the longest time, meaning a high time for speciation and species accumulation (Kozak and Wiens, 2010). In their study (Kozak and Wiens, 2010), they demonstrated that the time to speciation plays an important role in generating a humpback pattern in the case of North American salamanders. They demonstrated that the ancestors of all plethodontids existing in eastern North America were predominantly found at intermediate altitudes, and that species found at higher and lower altitudes colonized them recently.
