2. Alfred Russel Wallace, the father of zoogeography, was very influential to the field of biogeography. Born in 1823, he spent his life studying the connections between geographic variation between species and the physical features of Earth. Wallace noted the significance between geography and the creation of new species. For example, a species is separated into two groups on opposite side of a mountain range that forms. Over time, both populations evolve so much to their specific habitat that the
Neo-Lamarckism Future followers of Lamarck tried to modify Lamarckism in order to make it acceptable, based on the idea of adaptation and an intimate direct and causal relationship between structure, function and environment. Prominent Neo-Lamarckians like Mc Dougall, Giard (1846-1908), Cope (1840-1897), and T.H. Morgan believed that only those characters, which are incorporated into the germplasm, are inherited to the next generation and result in origin of new species. Under Neo-Lamarckism following
