Common ancestry relates to evolution because

• evolution only happens when there are common ancestors.
• Common ancestors make evolution happen more quickly.
• evolution can never take place with common ancestors.
• the more two organisms have in common, the more recent is their common ancestor during their evolution.

An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Which statement is best supported by the information in this dendrogram?

• Lesser pandas are more genetically similar to giant pandas than they are to raccoons.

• Brown bears are more genetically similar to giant pandas than they are to sun bears.

• Lesser pandas are more genetically similar to raccoons than they are to giant pandas.

• The bear species are all more genetically similar to dogs than they are to giant pandas.

What is the purpose of a cladogram?

• To map the ancestral relationships and shared traits of different organisms.

• To trace the inherited traits of a single species over time.

• To check the likelihood of an offspring having a particular trait.

• To monitor mutations that arise among different populations.
