Why do people die thousands of years ago and still have skeletons left?

Taxonomically man belongs to the animal kingdom, phylum Chordates, subphylum Vertebrates, Mammalia, Subclass Euzoa, Primates, Anthropoids, Homo family, Homo genus, Homo sapiens. So from a biological point of view, no one can deny that man is an animal. So human bones and animal bones are similar, there are animal fossils, and of course there are human fossils.

Isn't the Peking Man skull the fossil of our ancestors? It's just incomplete. The specific composition of bones is complex, and I can't explain it clearly, it contains calcium carbonate, which is the component of limestone, but human bones are by no means stone-like things.

It can be corrupted, but depending on the environment in which it is located, for example, if it is in a dry, neutral and mild environment, it can be stored for a long time, but if it is in acidic conditions, it will quickly corrode, and when it is hot such as cremation, it will turn to ash. The main component of bones contains a large amount of carbon, and the carbon atoms are stable at room temperature, that is, they do not decay. So the rest of the human body is rotten, and only the bones and teeth remain!

For thousands of years, there's usually nothing left.

But if the soil is loose and dry, it's possible to retain the skeleton, and the bones are mainly calcium carbonate, which is relatively stable.

Humans are also animals, and bones become fossils after being buried for a long time (at least tens of thousands of years).

The main component of bones is calcium carbonate, which is relatively stable.

Summary. We're happy to be able to answer your questions.

Here, the cottage wishes you a happy life and all the best.

The answer is as follows: a few minutes after death, the cells begin to die in batches.

Subsequently, the blood that had clotted together began to cause **discoloration throughout the body. The muscles are in a state of complete relaxation, and the bowels and bladder begin to empty.

Due to the large number of bacteria present in the body, the protein-rich internal organs in the body begin to decay, and the pancreas begins to digest itself.

Due to the action of bacteria, the body also changes from purple to black.

After a few weeks of death, the hair begins to fall out, and after about four months, only the skeleton remains.

How Long After Death Does A Person Have A Complete Skeleton?

It is a pleasure to be able to answer your questions here, and the cottage wishes you a happy life and all the best. The answer is as follows: a few minutes after death, the cells begin to die in batches.

Due to the large number of bacteria in the body, the protein-rich internal organs in the body begin to decay, and the pancreas begins to digest the self-confidence.

Due to the action of bacteria, the body also changes from purple to black with the slippery locust. After a few weeks of death, the hair begins to fall out, and after about four months, only the skeleton remains.

Dear, the above is to answer the answer to "how long does it take for a person to keep a complete skeleton after death", please check if you think it is helpful to you, please work hard to like it! I wish you a happy life! Remember Qi Shen and all the best.

Summary. Hello! After our query and analysis, the answer to this question is:

As long as the environment is not very humid, it can be preserved, but the phalanges, phalanges and metacarpals are probably gone, and if it is a man, the bone is better preserved than a woman. If you're going to dig up the bones, I suggest you find someone who has experience in archaeological excavations, and you might be able to find more bones by excavating them using archaeological methods.

How long a human skeleton is preserved without protection is mainly related to the condition of burial at the time of death.

Oooooooooo I just want to know, 5 or 6 years later, I found bones, whether they are skeletons or piles.

Generally speaking, the jointed sacs (connective tissue), ligaments (connective tissue), and articular labials (cartilage) that connect the two bones are connected by connective tissue and cartilage, and even the inactive bone connections (i.e., non-articular connections) are connected by connective tissue and cartilage. Because the above substances are mainly composed of organic matter, and the main component of human bone is inorganic matter, after weathering, inorganic matter can be retained, inorganic matter remains, so that connective tissue, cartilage disappears, and bones are naturally separated from each other. Oooh.

It means that the bones are already separated, right?

It means that the bones are already separated, right? Yes.

The time required for the corpse to ossify is about 2 weeks under the action of maggots and putrefaction. Buried corpses ossified about 1 year later in the southern region, about 1 year in the Shanghai area, and about 4 5 years in the northern part of China. All factors that favor the growth and reproduction of putrefactive bacteria can speed up the process of corpse decay.

Otherwise, the decay of the corpse progresses slowly or even stops.

The main factors are:

1 The temperature of 25 35 degrees Celsius is suitable for decay, below 5 degrees Celsius or higher than 55 60 degrees Celsius, the growth and reproduction of decaying bacteria is inhibited or killed, and the decay of corpses can be slowed down or stopped.

2 Humidity Proper moisture is also one of the necessary conditions for the growth and reproduction of putrefactive bacteria, if the air is dry and well ventilated, the water of the corpse will evaporate quickly, and it is easy to form a dry corpse, and the decay can also be stopped.

3 Air The initial stage of corpse decay is mainly the action of aerobic bacteria, so the ground corpse exposed to the air with sufficient oxygen supply will decompose quickly; Due to the limited dissolved oxygen, the decay of corpses in the water progresses slowly; Bodies buried in the water are the slowest to decay due to lack of oxygen.

4 Factors of the corpse itself In general, obese people are weaker than thin people, and young children progress faster than older people;

Large-scale wounds and burns, bacteria are easy to invade, and the progress of decay is fast;

The corpses of suffocation, electric shock, and sudden death, the blood is not damaged and the flow state is conducive to the human blood, and its decay progress is faster. The opposite is true.
