Difference between a cladogram and a phylogenetic tree
Cladogram | Phylogenetic Tree |
---|
A diagram that shows the relationships between organisms based on the presence or absence of certain features. | A diagram that shows the evolutionary relationships between organisms based on the analysis of genetic and morphological data. |
Only shows the branching pattern of relationships between organisms. | Shows the branching pattern of relationships between organisms and also provides information on the time of divergence and the amount of evolutionary change. |
Does not have branch lengths or time scales. | Includes branch lengths and time scales. |
Can be constructed using only qualitative data. | Requires quantitative data and complex algorithms for construction. |
Used mainly in evolutionary biology for the purpose of grouping organisms based on shared derived characteristics. | Used to study evolutionary history and relationships between organisms at any level of classification. |
