I’ve heard this before but the explanation had nothing to do with he Romans. The plague also attacks white blood cells. In the area hardest hit by the plague those without this mutation died off. The survivors offspring have a higher incidence of the mutation about 15%. areas that were not as hard hit by the plague Asia an Africa have a lower incidence. This is the first time I’ve heard that Asians are also at around 15%.
Correct. The plague also uses the same pathway, and the Delta-32 mutation confers immunity to it. (if you have two copies, one from each parent).
Thanks!
“This is the first time I’ve heard that Asians are also at around 15%.”
Actually, if the black death allowed people with this mutation to survive, then it would make sense that it exists in Asia, as the plague originally entered the Mediterranian ports from the East, and then moved west and north. Public TV had an interesting show on this a while ago.
