The exact origin of Rh negative blood is not fully understood, and it remains a subject of scientific debate and speculation. However, there are several theories regarding its origin.
One theory suggests that the Rh negative blood type may have originated from genetic mutations in Europe. It is believed that around 35,000 years ago, a genetic mutation occurred that resulted in the absence of the Rhesus (Rh) protein on the surface of red blood cells. This mutation spread among populations in Europe and became more prevalent over time.
Another theory proposes that the Rh negative blood type could have originated from ancient astronaut theories or extraterrestrial contact. However, it’s important to note that this theory lacks scientific evidence and is considered more of a pseudoscientific speculation.
It is worth mentioning that the Rh factor is a specific protein found on the surface of red blood cells. A person can be Rh positive if they have the protein or Rh negative if they lack it. Rh negative blood is relatively rare, with about 15% of the global population being Rh negative. It is more common among certain populations, such as Europeans, and less prevalent in other regions, such as Asia and Africa.
While the origin of Rh negative blood is still not definitively established, it is generally accepted that it has been present in human populations for thousands of years.
