SCI203 Phase 2 Lab Report SPECIATION Sharon Patton June 1‚ 2015 Colorado Technical University Purpose The purpose of this lab is to explain what would happen if a species were split into two groups by an earthquake‚ creating a physical barrier between the two groups. Showing how the formation of a new species can evolve. Introduction Speciation is when a species is created from the splitting of a species. In other words if a group of a certain species is separated say by an earthquake

MnO4¯ + 8 H+ + 5e¯ → Mn+² + 4 H2O (1) In the above reduction half-reaction‚ manganese has undergone a decrease in oxidation number from +7 to +2. In the following oxidation half-reaction‚ each iron atom has undergone an increase in oxidation number from +2 to +3. Fe+²→ Fe+³ + e¯ (2) Oxidation must occur along with reduction. These reactions are called redox (reduction/oxidation ) reactions. The number of electrons lost and gained
