I haven’t seen explanations for the result. I’ve seen statements that the data exhibits a medium amount of homoplaises, and assertions that SCD can account for this. Without an explanation how, and not having expertise in the area, all I can do is offer my thinking why the ID conclusion seems the most plausible in my mind. Not trying to disrespect anyone here.
But, still the main takeaway is everyone agrees with Dr. Ewert’s result that pure trees are bad models for the data, and some sort of dependency injection is better, correct?
