Locard
When two objects come into contact there is always a transfer of material from each object to the other. Often this transfer is obvious, at least in one direction, but even the amount of material transferred, or its nature is such that nothing is visible. There is always some transfer.
If you mean the cascade principle; that is a principle connected to evolution in Cellbiology.
This is the Pauli exclusion principle. Wolfgang Pauli was a Jewish physicist, Nobel prize laureate.

Edmond Locard was the first person to apply principles of forensic science to a working crime laboratory. He applied what is called the Locard's exchange principle to a working crime laboratory.
An example of the Locard Exchange Principle in a crime is if someone is strangled to death and you find a suspect with the victim's skin cells under his nails. The case is then solved. The Locard Exchange Principle helped with this case because it shows that during the contact of the victim and the murderer (during contact of two surfaces), the skin cells were left on the murderer's nails (transfer of evidence is created).
Every contact leaves a trace.
Edmond Locard was the first person to apply principles of forensic science to a working crime laboratory. He applied what is called the Locard's exchange principle to a working crime laboratory.
Locard's Principle states that every contact leaves a trace. This means that whenever two objects come into contact, they will exchange materials such as fibers, hairs, or fluids, which can be used as evidence in forensic investigations. The principle is fundamental in forensic science for linking suspects, victims, and crime scenes.
Dr. Locard was the first Forensic Scientist. His theory was that anytime a person comes into contact with anything, they leave silent evidence that they were there. The suspect of a crime will leave evidence that he was there, and like wise, he will take evidence with him.
