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]
The rate of decomposition is governed by three sets of factors: the physical environment (temperature, moisture and soil properties), the quantity and quality of the dead material available to decomposers, and the nature of the microbial community itself. [64] Decomposition rates are low under very wet or very dry conditions.
McHenry travels regularly to Africa to extend his knowledge of human origins, focusing his studies on the fossil remains of australopithecines.The best-known of which are the 3.2-million-year-old remains of 'Lucy', discovered in 1974 by Donald Johanson of the Institute for Human Origins.

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 ...
Transcendence: How Humans Evolved Through Fire, Language, Beauty, and Time is a non-fiction book by Gaia Vince published in 2019. It describes how human evolution was shaped by genetic, environmental and cultural factors. It has been reviewed by several science publications, including Nature.
The book lent its name to the 2005 film about Sally Mann, What Remains: The Life and Work of Sally Mann, [3] in which Mann can be seen at the University of Tennessee's anthropological facility, taking photos for the book of corpses which had specifically been left outside for scientific study of human decomposition.
