What is the main difference between phylogenetic trees and cladograms?

• Phylogenetic trees show evolutionary time and distance, while cladograms show relationships

• Cladograms show evolutionary time and distance, while phylogenetic trees show relationships

• Phylogenetic trees focus on physical traits, while cladograms focus on genetic traits

• Cladograms focus on geographical distribution, while phylogenetic trees focus on behavior

What does the root (base) of a cladogram represent?

• Descendants

• Ancestor

• Speciation event

• Recent lineage

What does branching in a cladogram indicate?

• The extinction of a species

• The evolution of a new species

• The merging of two species

• The end of a lineage
