Essay

Refer to the figure.

-You are studying a remote island before and after a volcanic eruption. Data at Time 1 were collected one month before the eruption, and data at Time 2 were collected one month after the eruption. All of the species on the island are endemic. The island is 100 km across. Each animal icon represents 20 individuals. Species A and B (the two snail species) generally move a distance of only 2 m a day. Species C (the bird) often covers 20 km a day in search of food. After the eruption, the lava flow hardens, and the island is divided by a 20-km strip of bare rock with few if any resources these animals need to survive. Based on your knowledge of gene flow, genetic drift, and speciation, what do you predict will happen to these species over time? Do you predict that the current species will remain the same species or do you think they might split? How would you determine whether a species had split into two new species?
