...the A and B mutations are more like each other than either is like group O.

The difference between having the gene for type A blood or type B blood is a variation of a mere seven letters out of the total of 1,062 that make up the entire gene. We even know exactly where they differ: letters number 523, 700, 793 and 800. If you are type A blood, you have C,G,C,G in these locations, whereas if you are type B blood you have G,A,A,C there instead. These are called 'point mutations' because they are a simple one-letter misspelling in a gene, unless as in the case of blood type it is a consistent variation, in which case it is called a polymorphism.

The type O gene mutation is even more interesting. It is a 'frame shift mutation'; if you are type O you may be surprised to discover that rather than having a difference of letters, like A and B, type O is missing one letter, number 258, entirely.


1.  Utterly fascinating and informative post, Dr. D.

2.  258!  My kingdom for 258!

Some of the more Biblically well versed might  scan Genesis again with all this in mind. I'm out on a limb here but I recall some mention of distinctly seperate hunters, tillers of the earth and herders of animals all being in position for the offspring of Adam and Eve to be fruitful and multiply with. As an -O- I admit I enjoyed, until reading this new take on blood type, the misconception of being with the original crowd but somehow this makes more sense.

Car 258 where are you?

fascinating, Lola, but I could not figure out how to pursue a line of inquiry.....or to understand it. What we need is "resting's" deductive reasoning powers to digest this for us!!!!

Wasnt PT's old screen name Car54?  

Also, on Wikipedia..............according to what I saw the other day on TV, Wikipedia should be taken w/ a big grain of salt as they said anyone can go in and change anything. If that is true............

I can see where there's molecular sense to the argument that all the types co-existed, or that A was first, but at first glance it doesn't make anthropological sense.

My understanding was that we were hunter-gatherers for millennia before we even thought of domesticating and herding any beasts, or clearing some ground and planting hoarded seeds to deliberately make a crop. If that's true, then either _everybody_ went around being sick and woeful most of the time - the A-came-first hypothesis - or half of everybody went around sick and woeful - the all types were present from the start hypothesis.

By that I mean, if everybody is doing nothing but hunting (meat or seafood) and gathering (nuts, berries and various non-grain plants), then the B people are not well served by the available diet (no milk... we haven't domesticated ungulates yet... so no cheese, yogurt, kefir, etc.), and the A people are not well served by the available diet (no agriculture at all) for tens- or hundreds-of-thousands of years.
The O folks would have been carrying the sickly A and B folks for a lo-o-o-ong time (thousands of generations?) before somebody invented domestication and herding and somebody else invented plowing and weeding and cities (so we could develop diseases-of-crowding and kill off some Os).

That's a long time to be (relatively) sickly and yet survive, generation after generation.

So where does that logic fail?

actually, I have read that the hunter- gatherer should be called "gatherer-hunter" as a great deal of the diet was in fact gathered, as in roots, berries, fruits, tubers, nuts, etc........which does not preclude type A flourishing, and don't forget the great apes or whomever we evolved from may not have eaten meat .........hmmmm?

Oh yeah, don't forget that there was supposed to be a leap in brainpower when humans began to hunt and eat meat....( I can't help it if thats my type)

A was first, but at first glance it doesn't make anthropological sense.


When you look at other primates, it might.  (Bear in mind, though, that I am merely an anthropology undergraduate and have done only superficial reading on the matter.)  And it is not completely straightforward, either.  But my understanding is that the AB antigens are extremely close in primates but not identical to homo sapiens.  Nevertheless, chimps are mostly something like type A with some being type O; gorillas are mostly something like type B with some being type O.  This makes it look like any common ancestor might already have had the two antigens or absence of them.  And perhaps they were predominantly type A, there probable diet would have that makes sense.  Parallels with chimps work pretty well - they are not agriculturalists but gathers, but they are largely vegetarian; though I do not know what might be different with gorillas that they became predominantly type B.

Australopithecus adopted a very different diet - hunting and consuming much greater quantities of animal products.  So, maybe they were mostly type A to start, but their different diet, which helped them develop into homo sapiens, favored type O.  But since primates are social creatures, the stronger and healthier members of the group probably would have helped those who were not as well off.  And certainly it makes sense that as the hunting/gathering homo sapiens spread across the globe, type O was favored.  (Heck, if any As or Bs ventured further and further away from "home" in the first place, they certainly died out along the way!)

Type A being the first type (or at least having developed in Africa) goes a long way to explain a bunch of type A subtypes that show up in the continent.

I see your point.  But look at how things are today.  Most people are not eating for their type, and a generally healthy person does okay up to about age 50-60 before things start going really wrong.  That's plenty of time to pass the blood type on to a new generation.

That's an excellent point, and one that I've made in other discussions, so you'd think I'd come up with it in this context.  Must be something I ate.      

Oh well. Thanks for a thoughtful post.
