A controversial theory has sparked discussions about the origins of humanity, linking the eight survivors of Noah's Ark to the eight main human blood types.
According to the Bible, Noah, his three sons, his wife, and his sons' wives were the only ones who survived the flood, and later became the ancestors of every human being today.
Some researchers and enthusiasts have noticed a surprising modern coincidence: the eight people on the Ark and the eight main blood types known to medicine.
Human blood is classified according to the ABO and Rh systems, with four main groups A, B, AB, and O, each Rh-positive or Rh-negative, giving eight common blood types: A+, A-, B+, B-, AB+, AB-, O+, and O-.
The theory has sparked a debate on social media, with believers seeing it as evidence of a divine plan. One user wrote: “The Bible is a living blueprint of the human body.” Skeptics, however, are quick to counter: “Interesting coincidence, but blood types evolved over tens of thousands of years, not from a single herd.”
However, genetics show that ABO and Rh groups are inherited from parents. Even a small, close group could produce all eight types over generations. With just eight people on the Ark, the mixing of inherited alleles could have created the full range of blood types we see today, giving an ancient story a surprisingly modern twist.
Blood type O, the most common in the world, may have originated in a member of Noah's family and spread naturally as the population grew, suggesting that a small founding group could explain modern human blood diversity.
Scientists point out, however, that blood types evolved over thousands and millions of years through genetic mutations and natural selection, largely to enhance immunity to disease. Early forms of the ABO system have been identified in primates over 20 million years ago, with type O being the oldest. The other groups evolved later as adaptations to specific environmental pathogens, showing the complex history of human blood evolution.
Despite evolutionary explanations, the theory continues to spark debate online and in academic circles. Supporters see the numerical match as more than a coincidence, while critics argue that modern evolutionary genetics renders the connection merely symbolic.
Some users have pointed out that the eight people on Noah's Ark were all close to each other: Noah, his wife, his three sons, and their wives. Even if some think the wives may have been sisters, this suggests that the post-flood population started from a very small and close-knit group, leading to a high degree of family ties in the first generations. /GazetaExpress/
