I can support with evidence that common ancestry and biological evolution are supported by multiple types of evidence.

This diagram is a best guess at how these organisms may be related.
The base of the tree represents and the top represents
What occurs at each branch point?
The branches are defined by the differences in the traits of the descendants.
What trait evolved in the lineage after the first branch point?
What trait evolved in the lineage after the second branch point?
What trait evolved in the lineage after the third branch point?
What trait evolved in the lineage after the last branch point?
Which two organisms share the closest common ancestor?
Rotating the order of the organisms at the top of the tree changes the relationships between them.
What evidence supports the order of the organisms?
Evolutionary trees are 100% correct and are not redrawn.
