We now know that blood type O is the oldest blood type in the history of humanity. They were the meat eaters of the human race, and this trait has been handed down though the centuries to modern man.
Blood type A was the more herbivorous kind, as migration to Europe and Asia from Africa meant that Type A people slowly developed systems that were better at digesting carbs as against O type people, whose digestive systems handled meat better than fruits and vegetables.
History
The third blood group in the human race is blood type B. The movement from eastern Africa continued past Europe and Asia toward the Himalayas, which is a part of India, Nepal, Tibet, and Pakistan today. This was a move from hot to cold climates, and it is believed that blood type B may have been a mutation based on this climatic change. Blood type B also established its presence in the Ural region of Asia, where the populace was a mix of Mongolian and Caucasian tribes.
The Mongolians moved through Asia and dominated the Eurasian Plains, and soon blood type B was as good as set in this segment of people. The northward movement heralded more animal domestication, so the diet slowly turned more toward dairy and meat.
This blood type has the clearest geographical outline as compared to others. Japan, China, Mongolia and India have the maximum B type group people with the Koreans and Chinese of North heading the list. Further west, blood group B is seen in people, where there is evidence of Asian nomadic migration.
B type people are flexible. They can adapt to their environment quite easily. This is the outcome of the ancient tribes who were learning to balance both a vegetable and animal-centric diet.
