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
Phylogenetic tree also shows evolutionary time. This allows you to track how a species has changed over time.
a cladogram represents distance of relatedness in time and trait similarities
a phylogenic tree produces a new branch for every unique trait being observed
The diagram below represents possible genetic relationships between groups of organisms.
Which statement is a valid conclusion that can be drawn from the diagram?
