evolution

natural selection

branching tree diagram

convergent evolution

If two species have very similar structures, they may have evolved from

the same parent

a common ancestor

a branching tree diagram

similar offspring

Branching tree diagrams tell you the order in which a specific set of characteristics may have evolved.

True

False

Similar looking organisms that are NOT related are an example of

natural selection

convergent evolution
