Create professional cladograms based on shared traits between taxa. Add organisms and their characteristics to visualize evolutionary relationships for education, research, and presentations.
Your cladogram will appear here after you build it.

A cladogram is a diagram used in biology to show evolutionary relationships between organisms based on shared derived characteristics. Unlike phylogenetic trees, cladograms focus on relatedness rather than evolutionary time or genetic distance.
Key features of cladograms include:
Cladograms are essential tools in cladistics, a biological classification system that groups organisms based on their most recent common ancestry and shared derived characteristics.
For quick learning, try the pre-built examples for vertebrates, plants, or insects to see how cladograms represent evolutionary relationships within these groups.
Used in biology classrooms to teach taxonomy, evolution, and biodiversity. Helps students visualize evolutionary history and classification principles.
Essential in evolutionary biology, comparative genomics, and phylogenetics to determine relationships among species and clarify taxonomic classifications.
Helps prioritize species for conservation efforts by identifying unique evolutionary lineages and phylogenetic diversity within ecosystems.
Cladograms show relationships based on shared derived characteristics, while phylogenetic trees additionally represent evolutionary time and genetic distance. Cladograms focus on branching order rather than branch length.
Our tool uses a similarity algorithm that analyzes shared traits between taxa. It calculates similarity scores and creates a hierarchical structure by grouping taxa with the most shared characteristics.
CladeGram Pro is excellent for educational purposes, preliminary research, and data visualization. For advanced phylogenetic analysis with genetic data, specialized software like MEGA, MrBayes, or RAxML is recommended.
While there's no fixed limit, the tool performs best with 5-15 taxa. Too many taxa may make the visualization cluttered, particularly in radial layout. For complex analyses, consider breaking down into multiple cladograms.
| Clade | A group consisting of an organism and all its descendants |
| Monophyletic | A group that includes a common ancestor and all its descendants |
| Paraphyletic | A group that includes a common ancestor but not all its descendants |
| Polyphyletic | A group whose members derive from more than one common ancestor |
| Outgroup | A taxon used for comparison that is not part of the group being studied |
| Synapomorphy | A derived trait shared by two or more taxa inherited from a common ancestor |
| Sister Taxa | Groups that share a more recent common ancestor with each other than with other groups |
