jan 1, 1628 - Blood Evidence: William Harvey publishes his discovery of blood circulation (Key event for blood evidence)

Description:

Harvey's Exercitatio Anatomica de Motu Cordis et Sanguinis (On the Motion of the Heart and Blood) proves that blood circulates through the body in a closed system. This revolutionary understanding of how blood flows is essential background knowledge for later forensic analysis of bloodstain patterns, understanding directionality and volume requires understanding how blood moves through the body. The key foundational event is the discovery of blood circulation because it allowed forensics to understand bloodstain patterns.
