Phylogenetic signal

[4] Phylogenetic signal is a measure, closely related with an evolutionary process and development of taxa.

It is thought that high rate of evolution leads to low phylogenetic signal and vice versa (hence, high phylogenetic signal is usually a consequence of either low rate of evolution either stabilizing type of selection).

[4] With a help of phylogenetic signal we can quantify to what degree closely related biological taxa share similar traits.

[6] On the other hand, some authors advise against such interpretations (the ones based on estimates of phylogenetic signal) of evolutionary rate and process.

Within other models (e.g. functional constraint, fluctuating selection, phylogenetic niche conservatism, evolutionary heterogeneity etc.)

The phylogenetic tree above shows significant phylogenetic signal in the mimicry structure of the community . This display confirms closely related species share color patterns more often than expected at random.
