Phylogeny - Help me see what you see

Has anyone tried to measure the quality of phylogeny within creationist “kinds” vs external to “kinds?”

The YEC separate ancestry hypothesis has been tested and compared with common ancestry.

Testing separate ancestry vs common ancestry using a concatenated dataset of 54 different genes across 178 taxa refutes the creationist “seperate ancestry” hypothesis in favor of common ancestry

Statistical evidence for common ancestry: New tests of universal ancestry

If you want a more manual, visual and easy to explain explanation of how this works you can see a phylogeneticist do manual analysis of mitochondrial genes ND4/ND5 -

Some molecular evidence for human evolution

I wrote this several years ago, but I think it’s a useful introduction to molecular data, even though the method is not one anybody actually uses in phylogenetics. Here is a set of DNA sequences. They come from two mitochondrial genes, ND4 and ND5. If you put them together, they total 694 nucleotides. But most of those nucleotides either are identical among all the species here, or they differ in only one species. Those are uninformative about relationships, so I have removed them, leaving 76 nucleotides that make some claim. I’ll let you look at them for a while.
