In response to
Chris Noël’s comment on Melba’s Ketchum’s FB page that I was “slamming” her sasquatch
conclusions on the Internet (to which I
totally confess) , Melba Ketchum posted the following on her FB page:
“1. His degree is not in a discipline that
allows him to be qualified to review the paper. 2. He didn't use bioinformatics
software which has to be done in order to evaluate the data.
3. You can't use only statistics to evaluate the sequences nor by tearing it down into little sequences unless you have software/expertise to do so.
4. He early on discounted the mtDNA findings using the wrong reference sequence. 5. He then changed his mind and said the mtDNA human sequences were correct 6. He reviewed the paper and said our nuclear DNA findings were correct and told me I could post his positive review (I have it in writing). However, I didn't post it because he is not qualified to review the paper and he even stated so in his correspondence. Now, he has changed his mind again and says the nuDNA is incorrect but he's not acknowledging that he's not qualified to review the manuscript. I have generally just ignored him for all of these reasons.”

I post my response here, since she defriended me on FB
quite some time ago:
The first 6
comments correspond to her numbered comments above.
1. Melba’s degree is in veterinary medicine, NOT genetics
or anthropology, or even biochemistry.
By her criterion she is not qualified to write the paper she did, nor
are ANY of her coauthors. Many people
change their professional orientations/interests. Melba has no degree in forensic science, yet
testifies in court on her DNA findings, in capital cases. My Nobel Prize winning PhD thesis advisor
said he never decided between biology, chemistry, or physics. He got the Nobel Prize in chemistry for his
interdisciplinary work. Any respectable
chemist understands DNA enough to do what I did. It’s a chemical compound, or more accurately
a family of related compounds, differing by mutations of the bases.
2. I used the same
bioinformatics software, BLAST™ from NCBI, that she did. It doesn’t take special software to tear a
sequence down into little 60 base pair segments as HER colleagues did. The analysis can be done on Microsoft® Excel.
3. My paper did
not involve tearing down a nice long sequence into little bits, loosing information
as you do so. That was her colleagues’ approach, which experts
at the NCBI said “makes no sense.” I did
this as a side exercise to compare results to hers. I am confident that her team never tried to
align S26 against a bear or S140 against a dog and compare those to the human
alignments. I did, and the alignments,
by both her method and mine (which searches the whole sequence), favor bear and
dog, respectively, over human or any other animal. I have used numerous databases throughout my
career and hold two US patents for inventing databases (US 6,732,054 and US 7,532,785) as
explained in the Preface to my first paper.
4. Her Supplementary Data 2 was poorly constructed with no headings, footnotes, or text explanation. It took me awhile to realize that there are two types of data in it: HVR-1 only and full sequences. This should have been explained in her paper. There are even two sequences off to the lower right that are not identified in table or text, labeled, or aligned with the rest in columns. Some mutations have no suffix (A, G, T, C). She took some raw output and never even bothered to critically examine it or make it intelligible to a reader. “Supplementary” does not mean unexplained or unformatted.
As an example of how confusing her Supplementary Data 2 is, read the following from an experienced genealogist, A. John Marsh. Melba had, of course, posted on FB his conclusions on the T2b samples as evidence of support. He was totally confused by her very sloppy reporting in Supplementary Data 2 and had to retract his posts. I guess I can be excused for changing my mind too.

· Hi Haskell,
·
See my earlier reply to you
where I noted that I had
made a mistake, in that some sequences were using rCRS as the reference,
and some were using RSRS. Family Tree DNA did the mtDNA sequencing, but
they apparently did it a year or more ago when they used the rCRS reference,
but now they use the RSRS reference.
·
When I get back from a trip
on Friday, I will have a fresh look at T2b.

Regards,
·
John
“I would rather you did not
quote me on anything to do with T2b Bigfoots until I can reevaluate
things. I have made a posting on the genealogy-dna list confessing my
error.”
NOTE: I never heard back
from John, nor have I seen any more of his posts on Melba’s FB. Since this exchange I have shown that Samples
2(T2b), and 39b(T2) are outside the range of human mutations, Sample 12 (T2b)
is marginal at 2.3% chance of occurring, and only Samples 1 (T2b) and 36 (T2b)
are from a human population. These and
related results are explained in my second paper.
*****************************************************************************
5. I pointed out mtDNA
anomalies to her early on in my first review.
I have published on the Internet a full analysis of these sequences in
my second paper. Many are anomalous to
the point that they do not match any of the 27,156 complete human mtDNA
sequences in the NCBI Nucleotide database.
Nor do these fit into the mtDNA PhyloTree of accepted human haplogroups. Eight of 18 samples with complete sequences
have less than 1% chance of belonging to the human population, contrary to a
position she has steadfastly maintained for all of her mtDNA samples. This is further explained in my second paper.
6. She (Robin,
her publicist) DID ask for and received permission to post my comments, which
she did on Melba’s FB page. She
misspelled my name and ADDED “Way to go Melba Ketchum” without my permission. See my previous blog.
7. I shared my results at every turn with Melba,
hoping for some constructive feedback, but I got none. In her last note to me she referred to it as
“nastiness” without explanation. I have
since ceased direct communication. Before
this she called me and we talked for about an hour on general subjects until
she finally asked me not to publish my first paper that is now on the
Internet. Her only reason was that she
had access to much more data (four terabytes) and it all pointed to the
existence of sasquatch. Apparently most
of it did not appear in her paper. I
did receive some of her colleagues’ results and conclusions on her sequences through
her. She asked me not to share these, and I haven’t. They wish to remain anonymous (One might
wonder why.). She unfriended me on FB,
so I cannot respond to her there.
Science does not do “anonymous.”
These coworkers should have been mentioned in her paper as should their
database search results.
8. I clearly
indicated my background in the preface to my paper. People can judge for themselves whether it is
adequate to compare a string of only four possible letters: A,T,G,C (with some
rare minor variations). This is all I
ever did. I accepted and used her
published results (the sequences) without comment about how they were produced.
9. I have shared
my first paper with two renowned geneticists/anthropologists familiar with her
work, and both have made positive comments.
Also, both of the anonymous reviewers made positive comments about my
methodology when I attempted to publish my paper in an online journal (their
comments are in the Preface to my first paper). The reason it wasn’t published was because
the editor took the position of one reviewer that it was essentially based on
her unacceptable results and conclusions:
“There is no scientific evidence that any other
hominids currently live. The only reference is to a paper in a journal that has
only one edition. If there was any evidence then a publication such as Nature
is the more likely journal in which this would be published.”
10. Changing
one’s mind is scientifically in order as long as reasons are explained openly
and honestly, as in my paper. Clinging
to conclusions that have been shown to be unsupported by one’s own results while
not critically answering the challenge is unscientific. Real scientists debate issues openly. They don’t “just ignore” them. Reasonable people can disagree, but
scientists base their disagreement on their own work AND critical analysis of
opposing views. The latter has as yet
not been heard from Ketchum.
11. On one
website alone, nearly 100 people have downloaded my first paper. A few have asked questions or made positive
comments. NO ONE has commented
negatively or pointed to any error. The
topic of the Ketchum paper had previously attracted thousands of comments there,
positive and negative. Since I posted my paper it’s been close to dead
silence. I welcome critical comments and
have said so. Melba doesn’t.
Haskell - Thank you for creating this blog and sharing your work, I'm sure I will be a regular visitor.
ReplyDeleteBruce, thanks for the feedback. Please send me more, whether positive or negative. I'm not the last word. I'm especially interested in knowing whether anyone can follow my three tutorials on using BLAST(TM).
