Hello,
I have created a mega-phylogeny tree for angiosperms using Mr.Bayes software after concatenation of rbcl, matK, Trnh-psba and ITS genes. My final tree consist with several exceptionally long branches. What is the reason for such long branches ? is that incorrect to have such a long branched in a phylogenetic tree?. (I rechecked the possible alignments errors but for me there is nothing wrong with the alignments).
Thank you all.
We should ask if phylogenetic trees are correct at all, since they are based on evolutionary assumptions, which many scientists (me for one) do not accept. So I'm sorry I can't help :)
It depends what do you mean by long branches. You should attach an image and point them out. Sometimes Bayesian methods are known overestimate branch lengths. Article When Trees Grow Too Long: Investigating the Causes of Highly...
