Fossils, is it direct evidence to study the question of human origins?

Base sequence It seems that Meijiali is engaged in random street gangs to test the base knot and found that several ancestors made documentaries and forgot what to call.

The role of fossils in our study of early humans: fossils can help people better understand the people of ancient times, which is of great help to the archaeological community.

In addition to these fossils, there are other forms of formation. For example, some animals leave traces on the earth's surface, and these traces are fossils. In addition, amber is also a special type of fossil.

Amber is the resin of trees that were built millions of years ago. These resins undergo a series of physical changes and become amber fossils. Some amber also contains insects, such as ants.

This is because insects like ants are accidentally encased in amber when it is still resin. The word fossil describes a wide variety of natural products. In general, a fossil is any evidence of past plant or animal life preserved in the earth's crustal material.

But when most people talk about fossils, they are referring to a special branch of this group - fossils, in which the shape of an animal or plant is preserved, while the true organic matter of its body is lost. These amazing monuments date back to prehistoric times and were slowly formed by dynamic geological processes.

<>In most cases, the fossil process begins with the rapid covering, usually at the bottom of a body of water, after the death of a plant or animal. Loose sediments protect the remains from the elements, bacteria, and other forces that cause weathering and decay. This slows down the decay process, so some remains are preserved for thousands of years (in most cases, only hard materials like bones or shells).

During this time, layers of sediment are constantly piling up on the bones. Eventually, these sediments become hard, solid rocks.

At some point after the formation of the hard rock, water seeps through the rocks and washes away the preserved remains. Due to the hardness of the rock above, it did not fall into the clearing where the wreckage was. This clearing forms a natural animal model that perfectly retains the shape of the original ruins.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

It is the evolution of the remains or relics of living organisms and finally turned into stones, and some of them are fossils after the organic matter in the remains of organisms is decomposed; By studying fossils, we can learn about the human beings at that time, and at the same time, we can also understand the morphological structure of living things, and we can better understand the remains and relics. History can be explored.

In ancient times, the remains or relics of many creatures slowly turned into stone and were deposited with the movement of the earth's crust. It is possible to trace the origin of human beings, to understand the evolution of human beings, but also to understand their living habits, and also to understand their DNA.

After the organisms were buried, they underwent changes in the earth's crust and eventually formed fossils, which can give us a better understanding of the human body at that time and understand the evolution of human beings, which is conducive to the study of history.

No, do you look at the last few decades, have we humans evolved?

In addition to fossil evidence, what other ways to study the origin and development of human beings are there? What new ideas have scientists formed?

Try to be as complete as possible.

I'll answer with a reward.

Where there's a will, there's nothing.

In addition to fossil evidence, what are the other ways to study the origin and development of humans? What new perspectives have been developed by the Kobsan scientists?

Fossils are not the only evidence to study the evolution of organisms.

Knowledge Extension Exhibition:

Fossils are the remains of paleontology, relics or relics that remain in the rocks, most commonly bones and shells.

The word fossil is derived from the Latin fossillis, which means to dig. Fossils are the main research objects of paleontology, which provides evidence for Huaiyuan to study the life history of animals and plants in geological periods. There have long been records of fossils in ancient Chinese books, such as Ji Ran in the Spring and Autumn Period and Wu Jin in the Three Kingdoms Period, both of which have mentioned the "dragon bones" produced in Shanxi Province, and the "dragon bones" are fossils of bones and teeth of ancient vertebrates.

The soft parts of the organism's body are also found in the oily soils of East Poland, where the nose horns, forelegs and part of the skin of a well-preserved extinct rhinoceros are found. Naturally occurring mummies of ground sloths have been found in caves and craters in New Mexico and Arizona. The extremely dry desert climate allows the soft tissues of the animals to be dehydrated before they decay, and some of the skin, hair, tendons, claws, etc. can be preserved.

One of the more interesting and unusual ways in which organisms become fossils is by preserving them in amber. Ancient insects were captured by sticky gums secreted by certain conifers. When the pine resin hardens and turns further into amber, the insects remain in it.

Some insects and spiders are so well preserved that they can even study their fine hairs and muscle tissue under a microscope.

While the preservation of the soft tissues of living organisms has resulted in some interesting and breathtaking fossils, fossils formed in this way are relatively rare. Paleontologists more often study fossils preserved in rocks.

Fossils can also be preserved through mineralization and petrification. When mineralized groundwater deposits minerals in the space where the hard parts of the organism are located, the hard parts of the organism become harder and more resistant to weathering. The more common minerals are compounds of calcite, silica, and various irons.

Displacement, or mineralization, is the process by which the hard part of an organism is dissolved by groundwater, while other substances settle in the vacated area. Some of the fossils formed by displacement have their original structure destroyed by the displaced minerals.

The ancestors of man were not orangutans but apes.

There is also comparative anatomy.

About carbon-14 and DNA research

The study of embryonic and materialist dialectics of primates that are closely related to humans.

First of all, because of the understanding of the origin of life (five perspectives).

Origin of Life Perspective.

1) Creationism: Creatures are created by God or God;

2) Spontaneous generation theory: at any time, it can be completed in a short time;

3) Biologicalism: living organisms, but primitive creatures are unknown creationist colors;

4. The theory of cosmic life evolved over a long period of time in the universe (life was transplanted from extraterrestrial to the earth) 5. It gradually evolved through chemical pathways under the conditions of the primitive earth.

So far yes. Because it is impossible to determine whether ancient humans survived or not. So there is conjecture.

Darwin was the originator and researcher of this type of conjecture. Later generations followed the conjecture to find fossils, proving that there were human beings, and then it was the origin of Darwin, not the apes before the dead. Are apes the ancestors of our humans?

I'm not sure for sure, but I know that Darwin was the first fossil to guess and study.

When did the hominin fossils that were found belong to the homin? How is his age determined?

I don't know! Isn't it an orangutan?
