The original version of this manuscript  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)
We thank Dr. Simon Blomberg for pointing out the mistake.
