Phylogenetic tree (phylogram) A phylogenetic tree is an evolutionary tree that shows the evolutionary relationships between different groups of animals. Cladograms give a hypothetical picture of the actual evolutionary history of the organisms.

What's the difference between cladogram and Phylogram?
However, some biologists do use these words in more specific ways. To some biologists, use of the term "cladogram" emphasizes that the diagram represents a hypothesis about the actual evolutionary history of a group, while "phylogenies" represent true evolutionary history.
How does a cladogram differ from a Phylogram quizlet?
Terms in this set (9) Cladograms show the sequence of divergence whilst phylogenetic trees show the evolutionary history of an organism and the timeline of evolution.
How does a cladogram vary from a phylogenetic tree?
Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics. Phylogenetic trees compare organisms over evolutionary time and the amount of change that has occurred over time to figure out the relationships.
What is the difference between cladogram and molecular clock?
Molecular clock is a method used in molecular evolution that uses fossil constraints and their rates of molecular change to deduce the time of geologic history when the two species diverged. ... The length of the lines separating species on cladograms are used to represent the estimated time since divergence.
