Bouchard and Brooks Studied the Effect of Insect Flight on Dispersal

Multiple Choice

Bouchard and Brooks studied the effect of insect flight on dispersal and speciation in rain forest insects. They sampled all of the insects in the study area and found that 60 insect species are flightless and 19 are able to fly. What can you conclude so far about this study?
