Answer:
1.One type of evidence for evolution (evidence that organisms are related, descended from a few common ancestors, and change to adapt to their environments) is that organisms are similar to each other, but not exactly the same. Similar organisms have differences that help them adapt to their environments.
2.In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.
