Icelandic DNA Jigsaw-Puzzle Puts Together New Image of Neanderthals
” The properties and risks of diseases that can be linked to Neanderthal DNA are: slightly lower risk of prostate cancer, lower levels of hemoglobin, lower body length (one millimeter) and slightly faster blood plasma clotting.”

Thank you, Lesley, for bringing this to my attention. Indeed, the studies I am looking at are showing lower hemoglobin levels for Rh negatives.

Association between blood groups and blood hemoglobin levels in rural population of Kanchipuram district of Tamil Nadu
” Rh-negative blood groups had low hemoglobin values when compared with Rh+ve blood groups”

Another study has shown similar results:

… and there are many more.

We still have yet to see Rh factor data in western Neanderthal specimens.

As more and more studies highlighting Rh factor come to life due to the COVID-19 situation, we may soon see the data we’ve been looking for for years.

Stay tuned…

    fwiw – some comments/posts (w/ lots of quotes) i made on this study (from others who’d read it) back in September – i wasn’t focused on hemoglobin at that time though: https://www.rhesusnegative.net/staynegative/rh-negative-blood-factor-origins/#comment-11437

    my posts just above & below this one are also related to it. lots of info on many things is w/in this long thread: rh-negative-blood-factor-origins.

    this original study is here: Published: 22 April 2020 – The nature of Neanderthal introgression revealed by 27,566 Icelandic genomes https://www.nature.com/articles/s41586-020-2225-9 … but one must pay to access it.

    Staying tuned (and reading !).

    I am keen to see clearer delineation between ABO and Rh. The patterns for each combination (A+, B+, AB+, O+, A-,B-, AB- and O-) seem very different. In other words, the Rh factor seems to work differently for each major ABO group. Breakdowns by the multiple forms of Rh would be nice too.

    Haemogobulin seems critical too and may be connected to the recent progress on the role of the Rh proteins.

    My name is Kunnuk Takpanie from Iqaluit, Nunavut
    my blood type is RH negative A-
    No wonder the nurse said you have low hemoglobin. Thanks for sharing this. I have skin problem wonder what i am allergic too from having this blood type. Eczema on my legs, so itchy, was breast feed long time and no wonder i cannot take milk but I take it all the time. Just my guess because i take it on my coffee and my cereal, Thanks so much.

    Regardless of our blood types, we all need to stabilize our particular mix. The lab diagnostics are so amazing that it is usually possible to do that.

    On another them , this item came in to my genetics forum this morning.
    ” This is a preprint and so has not yet gone through peer review. The authors come up with the intriguing suggestion that East Asians were exposed to ancient coronavirus epidemics from ~25,000 to ~5,000 years ago, resulting in coordinated adaptive changes across at least 42 genes, and which might provide increased resistance to SARS-Cov-2.

    https://biorxiv.org/content/10.1101/2020.11.16.385401v1.full.pdf ”

    Mu first initial reaction is that East Asia has a heavy distribution of blood group B and that is not a coincidence.

    Technical analysis will take more time and effort!
