Hello everyone, On dead wood of Cytisus scoparius
Hallo forum,recently I read an interesting article about taxonomy and one of the main topics was the criticism of those widely employed phylogenetic trees. The authors' argument was, that these trees are always dichotomous by design and thus cannot reflect the reality of different and divergent evolutionary branches in the nature. As probably everyone here, I'm familiar with Korf's article about dichotomous vs. synoptic keys, so from this point of view their reasoning looked good to me. I wondered if there's been any polemic with this article and I was rather surprised, when I didn't find any reaction / citation at all. But I hope I must have overlooked some sources and perhaps someone here would have a tip on a follow-up or related article?
Also, if anyone has Vasilyeva's book Systematics in mycology (1999) in digital version, I would be much interested.
Thank you in advance.
Viktorie
