Microevolution is a change in the frequency of alleles in populations over time. Macroevolution involves large-scale changes such as the formation of new species. Evidence of macroevolutionary change is compelling. Sources of evidence include the following: biogeography, paleontology, comparative anatomy, developmental biology, and molecular biology. All of these lines of evidence contribute to our understanding of phylogenetic relationships.
Some opponents of evolutionary theory contend that evolutionary theory is not valid science because it concerns events of the past that cannot be observed or re-created in the laboratory. How would you respond to this criticism?
