In the year 1900, an Austrian Scientist, Karl Landsteiner, discovered iso-agglutination, the phenomenon wherein red corpuscles and serum of the animal species are clumped together. On carrying out further experiments on blood, Landsteiner discovered that agglutinogens when mixed with agglutinins of another blood types produced fatal agglutination.
These agglutinogens were named as A and B, and their respective agglutinins were named alpha and beta respectively. With this discovery, the question of blood group incompatibility was explained. Later, he discovered another blood type and named it O. In 1907, another scientist Jansky discovered a fourth type of blood, it was named AB. This discovery was corroborated by Moss in 1910. These agglutinogens and agglutins were renamed as antigens and antibodies respectively, specific to the blood.
Entamoeba histolytica was first discovered by Friedrich Losch in 1873. The pathogenic nature was first described in 1875.
Antonie van Leeuwenhoek is the scientist known for using single-lens microscopes to observe bacteria, human blood cells, and other microorganisms. He was a Dutch tradesman and scientist who made significant contributions to the field of microbiology in the 17th century.
No, human blood groups are not an example of a trait that shows continuous variation. Instead, blood groups (such as A, B, AB, and O) are classified as discrete categories determined by specific alleles. Continuous variation typically refers to traits like height or skin color, which exhibit a range of phenotypes rather than distinct categories.
If X is the set of all blood groups of human beings and Y is the set of all human beings then the association that associates a blood group to a person having that blood group is not a function from X to Y .
Physiologically speaking, the Anatomist studies Anatomy.
A cave man and the scientist
No - he was born in 1743 an died in 1826 - Austrian Karl Landsteiner discovered human blood groups in 1901.
Sociologist.
William Harvey, an English physician, is credited with the discovery of the blood circulatory system in the early 17th century. Harvey's work demonstrated that blood circulated throughout the body in a closed system, propelled by the heart. His findings revolutionized the understanding of human physiology.

Charles Drew is considered the doctor who discovered the Blood Bank Concept.

there's a film about it which really helped me to understand called the Human Centipede!
My answer is that you don't have a legitimately defined question. Please restate the question in reference to something. A & O may be blood groups in human.
