Common wild pig (boar) corpse decomposition timelapse. Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
This optimal temperature assists in the chemical breakdown of the tissue and promotes microorganism growth. Decomposition nearly stops below 0 °C (32 °F) or above 48 °C (118 °F). Moisture and air exposure: Putrefaction is ordinarily slowed by the body being submerged in water, due to diminished exposure to air.
The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.

Garvin: During decomposition, the body will undergo several phases. In early stages, you may get bloating or skin slippage as bacteria begin to do their job and tissues begin to break down.
A basic guide for the effect of environment on decomposition is given as Casper's Law (or Ratio): if all other factors are equal, then, when there is free access of air a body decomposes twice as fast as if immersed in water and eight times faster than if buried in the earth. Ultimately, the rate of bacterial decomposition acting on the tissue ...
Skeletonization is the state of a dead organism after undergoing decomposition. [1] Skeletonization refers to the final stage of decomposition, during which the last vestiges of the soft tissues of a corpse or carcass have decayed or dried to the point that the skeleton is exposed. By the end of the skeletonization process, all soft tissue will ...
Timeline of postmortem changes (stages of death). An example of postmortem corneal opacity. Post-mortem changes refer to the series of changes that occur to a body after death. These changes can generally be divided between early post-mortem changes and late post-mortem changes (also known as decomposition). [12]
The bodies are exposed in a number of ways in order to provide insights into decomposition under varying conditions. Some of the conditions students studied were situations such as a body being locked in the trunk of a car, or being submerged under water, which provided some factual and data driven knowledge to help in many forensic cases.
