Where did the O blood type originate?

The O blood type (usually resulting from the absence of both A and B alleles) is very common around the world. About 63\% of humans share it. Type O is particularly high in frequency among the indigenous populations of Central and South America, where it approaches 100\%.

What is the rarest blood type in the world?

AB negative
AB negative is the rarest of the eight main blood types – just 1\% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.

Is o the oldest blood type?

The other blood groups are tens of thousands of years old with B being more recent than A. The oldest group is either group A or one of the forms of group O.

What blood type did the first humans have?

Blood type A is the most ancient, and it existed before the human species evolved from its hominid ancestors. Type B is thought to have originated some 3.5 million years ago, from a genetic mutation that modified one of the sugars that sit on the surface of red blood cells.

Did Eve have the same blood type as Adam?

Because it is so common around the world, it must have arisen before the population breakup at Babel, perhaps even before the Flood. In this case, Eve would indeed have had the same blood type as Adam. If so, then the most likely scenario is that they both had type AB.

Did we all come from Adam and Eve?

Science confirms that eah person has an estimated 20,000-25,000; that most genes are the same in all people (only a difference of less that one percent between people); and we all inherited our genes from our parents. Thus, confirming we all came from the same ancestors, that we all came from Adam and Eve.

How did Eve get the a gene?

In this case, it’s most likely that the A gene was duplicated from Adam’s heterozygous AB, to make Eve AA. This would explain why A is much more common than B today. Here also, the O is an early mutation of A; there is general agreement about this among both creationists and evolutionists.

Was Eve homozygous or heterozygous?

So where Adam was heterozygous, not just in sex chromosomes but everywhere, Eve was homozygous. In this case, it’s most likely that the A gene was duplicated from Adam’s heterozygous AB, to make Eve AA. This would explain why A is much more common than B today.
