Erratum to: Revisiting phylogenetic signal; strong or negligible impacts of polytomies and branch length information?

The original article was published in BMC Evolutionary Biology 2017 17:53

Erratum

The original version of this manuscript [1] contained a mistake regarding the definition of Brownian motion model of evolution. This mistake does not affect the results of the manuscript, but it should be clarified.

Page 4. Second paragraph reads:

“Briefly, a BM model on a phylogeny describes purely neutral (random) evolution of a trait with variance proportional to the square root of branch lengths”.

and it should read as follows:

“Briefly, a BM model on a phylogeny describes purely neutral (random) evolution of a trait with variance directly proportional to the branch lengths”.

Also, there are two typos in the text:

“steaminess” should be “steminess” (third paragraph in page 5)

“Graphen” should be “Grafen” (fifth paragraph in page 8 and Conclusions)

Acknowledgements

We thank Dr. Simon Blomberg for pointing out the mistake.
