At that place'southward more than one way to mummify a corpse.

Ancient Egyptians adept maybe the most well-known method: extracting organs, embalming the body and wrapping the remains in linens. But nature tin make mummies too.

Such spontaneously preserved bodies can exist of tremendous scientific importance, like "Ötzi the Iceman," whose frozen remains were found in the Italian Alps or the Chinchorro cadavers that were buried in the Atacama Desert in northern Chile and safeguarded by the arid sand. These mummifications are made possible past environmental conditions that prevented human remains from naturally decaying.

"What you're looking for is something extreme," said David H. Thomas, an archeologist with the American Museum of Natural History in New York City. "It has to be really dry, or actually wet, or really frozen, or actually high height."

Bodies left in hot, arid environments can typically mummify in about two weeks, while the process typically takes a couple of months in enclosed locations. Remains in mild environments take about three months.

When a person dies the countdown to decomposition begins, equally digestive enzymes start breaking downwardly cells inside the body. When the person was live these enzymes were held within parts of the jail cell known as the lysosomes. But when the person dies, the membranes of the lysosomes weaken, allowing the enzymes to spill out and assimilate the prison cell.

In well-nigh cases enzymes need to exist in an aqueous surround to piece of work, so if the fluids are removed, decomposition slows downward. During spontaneous mummification, the body loses water more than rapidly than the enzymes' destructive actions tin can operate, according to Dario Piombino-Mascali, an Italian anthropologist and a visiting researcher at Vilnius Academy in Lithuania. Bodies cached in crypts can accidentally mummify if ventilation keeps them dry, as was the case in Lithuania'southward Dominican Church of the Holy Spirit where Dr. Piombino-Mascali works.

Not every part of the body mummifies at the same time. Some internal organs, like the heart, take longer to dry out . The easily, toes and scrotum are amidst the fastest trunk parts to dry out.

The environs tin speed up the desiccation procedure, often through extreme temperatures or pH levels that dull the enzyme activity. Sometimes the soil surrounding the body plays a large part every bit well either through osmosis or because heavy metals in the clay can impede the enzymes. Even wearing apparel can help mummification, according to Dr. Piombino-Mascali, because they can act equally a wick that absorbs bodily fluids from the pare.

In addition to protecting the remains from the torso's process of decomposing, the environmental conditions also accept to defend against external threats like leaner, fungi and animals in order to ensure that a mummy will final. But if all of these conditions come together but right — and no curse has been placed upon the remains — scientists might i 24-hour interval uncover the mummy and learn valuable information most the era in which it lived.
