2. Objective: You will be able to differentiate between the types of evidence that support evolution. Read p. 21-23 Define homologous structures?

13. Figure 24.5 Two main modes of speciation (a) Allopatric speciation. A population forms a new species while geographically isolated from its parent population. (b) Sympatric speciation. A small population becomes a new species without geographic separation.
