Cladograms / Phylogenic Trees

Each sub-grouping within a branch on a cladogram or phylogenic tree can be supported by a unique evolutionary novelty...

• True

• False

The main difference between a cladogram and a phylogenic tree is that...

• a cladogram does not produce a new branch for every unique trait being observed

• a phylogenic tree represents distance of relatedness in time and trait similarities

• a cladogram represents distance of relatedness in time and trait similarities

• a phylogenic tree produces a new branch for every unique trait being observed

How do we know when speciation has occurred?

• two organisms of different species can produce offspring

• two organisms of the same species no longer live in the same area

• when two organisms in the same species can no longer produce fertile offspring

• mutations occur and we see it in their DNA
