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]
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 ...
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.

Generally, the term decomposition encompasses the biochemical processes that occur from the physical death of the person (or animal) until the skeletonization of the body. Putrefaction is one of seven stages of decomposition; as such, the term putrescible identifies all organic matter (animal and human) that is biochemically subject to ...
It is the time lapse between death and discovery. After death, decomposition occurs. Decomposition includes physical, chemical, and biological changes. [19] Below are some of the biochemical changes that happen during decomposition which can help estimate the time since death (keeping in mind that there is variation between species): [20]
So, step into (pun intended) the world of the most expensive shoes ever sold, including insights into their sky-high price tags. 1. Michael Jordan’s ‘Dynasty Collection’ Air Jordans
Weeks into the drones-over-New Jersey mystery, the FBI and Homeland Security are finally stepping up to investigate and determine what threat, if any, they might pose. Garden State residents have...
The hominoids are descendants of a common ancestor.. Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes. [1]
