Feb 12, 2008 · Charles Darwin sketched his first evolutionary tree in 1837, and trees have remained a central metaphor in evolutionary biology up to the present. Today, phylogenetics—the science of constructing and evaluating hypotheses about historical patterns of descent in the form of evolutionary trees—has become pervasive within and increasingly outside evolutionary biology.
Suppose in a Bayesian phylogenetic analysis of 3 clades (A, B, C) you recover, each with probability 0.5, the following topologies: (A,(B,C)) and ((A,B),C). These topologies are incompatible, and it doesn’t make sense to demand a single phylogenetic tree that represents all sampled clades within a single tree.
Phylogeny definition, the development or evolution of a particular group of organisms. See more.
Phylogeny.fr is a free, simple to use web service dedicated to reconstructing and analysing phylogenetic relationships between molecular sequences. It runs and connects various bioinformatics programs to reconstruct a robust phylogenetic tree from a set of sequences.
