Phylogenetic Analysis

Reconstruct, view, interact with, and edit phylogenetic trees; bootstrap methods for confidence assessment; synonymous and nonsynonymous analysis

Build phylogenetic trees from pairwise distances of sequences and determine the evolutionary relationships between organisms. Estimate synonymous and nonsynonymous substitution rates using maximum likelihood. Visualize and edit phylogenetic tree data in the Phylogenetic Tree app.

Featured Examples

Building a Phylogenetic Tree for the Hominidae Species

Construct phylogenetic trees from mtDNA sequences for the Hominidae taxa (also known as pongidae). This family embraces the gorillas, chimpanzees, orangutans and humans.

Bootstrapping Phylogenetic Trees

Generate bootstrap replicates of DNA sequences. The data generated by bootstrapping is used to estimate the confidence of the branches in a phylogenetic tree.
