Colombian Blood Type
I was recently reading the book 1491, by Charles Mann. As I read, I came across the mention of a genetic bottleneck that had occurred among the Native American Indians. One of the examples given in support of this genetic bottleneck idea was that there is a predominance of type O+ blood among people of the Americas. Intrigued, I checked my family's blood type and indeed, they are all O+. Hmmm.
While in Colombia, on July 20th, we participated in a Blood Drive that was held at our local church. When I told the workers my unusual blood type, they were pretty shocked. According to them, they had never seen anyone with my blood type. It kind of worried me. I hope that I never need a blood transfusion in Colombia.
Do you have O+ blood? Are you Colombian?
