You'll recall that Dr. Melba Ketchum talks a lot about a lemur ancestral line leading to sasquatch. She got this idea from a phylotree that was generated from her sequence data for a sample (she doesn't say which sample), shown as Supplementary Figure 4 in her paper (Link on right). From Samples 26 and 140 she also generated her own phylotree for the primates as her Figure 16. (Link on right) The anthropologists (and quite a number of us laymen) were appalled. Figure 16 is not a tree - it has no trunk. It's a star. But forgiving for the moment the graphics, its very far from the established primate phylogeny, but I'll let the experts go to town on that. My question is: Where's the lemur which Melba still refers to as recently as last Sunday on the "Coast to Coast" radio show with George Knapp?
Answer: THERE IS NO LEMUR. The closest animal on her Supplementary Figure 4 and Figure 16 is Otolemur garnettii, but it's not a lemur, rather a galago or bush baby. See the NCBI taxonomy page on the right, How could this happen? I suspect that she didn't check this one. The other primates were described by their common names in the text of her paper, but this one wasn't - it is simply missing.
As if this isn't enough of a taxonomic scandal, it gets worse on Supplementary Figures 5 and 6. (Link on right). Figure 5 shows a phylotree with only a chicken (Gallus gallus), the mouse (Mus musculus), and 29 species of fish.(See my table below). Are these the closest relatives of sasquatch, a purported human-primate hybrid? I think not.
Supplementary Figure 6 shows a phylotree with only mouse relatives. Preposterous! Again, we don't know which of the samples 26, 31, or 140 this represents, but does it really matter?
I call to account those coauthors or consultants who produced these phylotrees. Did anybody even look up the common names of these species?
Melba always has a simple, usually totally uninformed, explanation for these things. She says the anomalous results are because her sasquatch samples are from an unknown species which confuses the NCBI software. Come on, those folks are way smarter than that. A primate-human hybrid will not show as closest relatives a chicken, a mouse, or any fish. It should be something like Supplementary Figure 4, which I guess is probably from the human Sample 31. Remember, "They're people just like us," says Melba.
These are "rookie mistakes," and should be recognized by all as such. Melba shouldn't be surprised by my comments; I sent them to her early last year. Oh, but hey, I'm not qualified to review her paper. She said so on FB.
