Biogeographic changes that occur in arizona
WebEvidence for large-scale evolution ( macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils. Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures). Molecular similarities provide evidence for the shared ancestry of life. WebAug 11, 2016 · The biogeographic regions identified by Alfred Russel Wallace from The Geographical Distribution of Animals (1876) Despite the long history of biological regionalisation, the methods to identify biogeographic regions are still being improved.
