The following graph depicts the relationship between the mean flower depth of Zaluzianskya microsiphon plants and the proboscis length of its long-tonged fly Disa nivea pollinator in a specific region. • Zaluzianskya microsiphon 60- O Disa nivea E 50- 물 40- 30- 20- 10- 10 20 30 40 50 Mean fly proboscis length (mm) Based on this correlation, do you think these two species are coevolving? Why or why not? And based on the geographic mosaic theory, would you consider the region were the plants and flies live a cold or a hot spot? Explain your answer. Mean flower depth (mm)

EVOLUTION ASSESSMENT - FINCHES Galápagos Ground Finches Between 1973 and 1978, the population of ground finches (a type of small bird) on the Galápagos Islands decreased. Scientists made observations of the population throughout that time period. They recorded and graphed differences in the distribution of traits over time. The two sets of graphs below come from the data they collected.
