comment If dinosaurs could have feathers, would they still be reptiles?
You say "Some dinosaurs actually had feathers". I'd go further and say that every taxon that we know of that has or had feathers is a dinosaur.

comment Is there a name for this phenomenon described in “Phylogenies and the Comparative Method”?
@AliceD The axes are arbitrary. X and Y don't matter, nor do their units. The point is to show that the apparent moderate positive correlation between X and Y in the upper figure masks underlying structure. When you separate by 2 monophyletic clades (boxes and Xs), there is clear separation and within groups there isn't any correlation.

comment What does the hominin phylogenetic tree look like?
No, it's fine as is. The tree is the tree and is (very likely) technically correct. It's just that the devil is in the details. I'm sure the bottom tree is equally poorly supported.

comment What does the hominin phylogenetic tree look like?
Great answer, but one thing to note about the upper tree is that the Bremer support values are really really low (0.2 to 0.5) particularly within Homo. So basically there is no resolution at that point. They may as well have a large polytomy at that point. This is not a fault of the authors but of all these fossils being fragmentary.
