I find this all very interesting. And if true, we know the blood type of Jesus. Type AB. So those of you out there with type AB, just think, you have the same blood type as Jesus!
Anyway, this shroud could be real just as easily as it can be a fake. Just because we cannot replicate it today, does not mean it cannot be done. Heck, we can not reproduce half of what is found in Egypt, yet those pyramids stand before us.
Bottom line, the people before us were not quite as useless as we seem to think. That of course does not mean the shroud is a fake, but cannot be used as a reason why it is authentic either.
I absolutely love historical mysteries and this one is one of the greats.
We could replicate the pyramids if we wanted to do so. Absolutely nothing stand in the way of that except the will to do so and the money to fund the project.
There is some science that seems to show that all old, degraded blood will show its AB. So that may be meaningless. Right now that finding is still being researched. There is other research that may show that AB was a much more common blood type in the past, but it no longer as common as migration and divergence of the populations changed the genotypes. Again, that is going to require more research.
