Define the following terms: species, speciation, allopatric speciation, and sympatric speciation. Explain how allopatric and sympatric speciation might work, and give a hypothetical example of each.
Name the two types of speciation represented by this diagram. For each type, describe how reproductive barriers may develop between the new species. (FIGURE CAN'T COPY)
Match each situation to the type of speciation that is likely to occur. 1. Small groups become spread out over many different islands with different habitats 2. A behavioral change prevents interaction between individuals from two groups 3. a valley becomes divided by a river, separating two groups Choices: Adaptive radiation, sympatric, allopatric
