Match the following scenarios to the type of speciation taking placeA population of 100 squirrels lives in a lush green valley. A sudden earthquake changes the flow of the local river, causing it to diverge through the center of the valley. About 45 squirrels are trapped on the east river bank, while the other 55 squirrels are trapped on the west river bank. The river is impassable. After thousands of years, the two sub-populations of squirrels accumulate differences that make them reproductively isolated.

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. what can be inferred from these observations? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
