So, this tree is based on both DNA and characteristics binning?
“So, this tree is based on both DNA and characteristics binning?”
That’s a good question and I would assume only the former.
Not based on DNA. Only an EXTREMELY tiny percentage of the total species have been sequenced, and for those that have been sequenced, and for those that have been sequenced, looking at just their DNA, it’s not possible to draw so-called tree-of-life relationships. If anything, the DNA genomic information contradicts the whole idea of the so-called tree of life.
