Evolution never occurs in a straight line. there are always branches and nodes that can be seen along the way. based on the image, which two statements are true?

Seeing as though you did not provide an image, I'm going to assume you are referring a phylogenetic tree. Two very distinct things are prevalent; one being species evolve from a common ancestor. Emboldening relationships shared between species. Furthermore, such diagrams show shared genetic characteristics.
