Scientists can use evidence to estimate how often a particular segment of DNA in a particular organism will undergo mutation. They can then locate the analogous segment in a related organism, tabulate the differences between the segments, and use this "molecular clock" to do which
of the following?
evaluate whether the mutations seen in the organisms' DNA will be maintained in the population
make an educated guess as to how long ago two species diverged from a common ancestor
predict the future forms that the organisms might take as they undergo mutations
compare the adaptive fitness of each species in different habitats
