The frequencies and distributions of blood groups have been studied for many human populations. Such studies give important clues to the movements of prehistoric and early historic peoples. Students play the role of a research team that is studying the blood-type frequencies of a population on an isolated island. Students try to determine if the natives are related to the people on nearby islands. Does the islanders' mythology hold clues to their history? The simulated agglutination reactions are extremely realistic. Kit contains no blood, blood products, or materials of biological origin, so there is no danger of disease transmission. Kit contains enough materials for a class of 30. Note: Use with Carolina® Synthetic Blood products and accessories only. Not designed for actual blood typing.
