The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
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.
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]
It is the time lapse between death and discovery. After death, decomposition occurs. Decomposition includes physical, chemical, and biological changes. [19] Below are some biochemical changes that happen (could help estimating time since death; stages/progress could vary a lot between species): [20]
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
With his work he wanted to highlight the horrifying aspects of the existence within these realms. The kusōzu were chosen to represent the impure aspect of human existence as the impurity can be understood through the decay of a corpse. [16] He states: "it is odorous and defiled [...]. But, if it is seen, all desires [for the body] cease." [17]
