This framework applies graph homomorphisms to understand migration patterns in cancers and viral outbreaks, suggesting new pathways for tracing spread.
Key Points
The study finds that structural constraints on migration patterns impact the relationship between phylogenetic and migration trees.
Phylogenetics often struggles to accurately reflect underlying migration structures, complicating our understanding of spread pathways.
Graph homomorphisms provide a new method for evaluating tree consistency under various conditions, offering enhanced flexibility.
By generalizing existing models, the proposed approach has the potential for wider application in tracing viral and cancer spread.
