levolution / Home

Welcome to levolution!

"levolution" is a computer program to infer the phylogenetic position and strength of evolutionary jumps along a phylogeny on any given morphological trait and any tree size. To do so, levolution will evaluate if the trait in question evolves according to Brownian motion (the null hypothesis) or under a jump process and then infer the position and strength of such jumps, together with other model parameters (e.g. root state, jump rate, variance under each model, etc).

This Wiki explains the basic usage of levolution. More details on the algorithm is found in our publication:

We kindly ask you to cite this paper if you use levolution for your analysis.
