The origin of blood type A

Blood type A: farmer

Date of production: between approximately 25,000 BC and 15,000 BC.

Subsistence mode: Fruits were the main food, while animals were domesticated for use, and they began to settle and live an omnivorous life, and farming became their main mode of production. The gradual enrichment of the diet led to changes in the dietary structure, which further caused the blood type to mutate, so blood type A was born.

Personality: People with type A blood have strong adaptability to the environment, careful and cautious, strong endurance, and strong sense of responsibility. The disadvantage is that they have too much self-esteem and are easy to be hurt by others.
