What changes are important markers of human evolution?

The important symbols of human evolution are: walking upright, using fire, language, grazing and farming, inventing muskets, and using electronics.

They are: Homo erectus, Monkey Ape, War Ape, and Program Ape.

In fact, there are many answers to this question, the use of complex tools, walking upright, the birth of language, the agricultural revolution. But in my opinion, in fact, the sign of human appearance is imagination, for example, we will construct an existence called God, and then worship, we can paint, we can turn a speech into a meaning, create language (animal language is all internationally used, human beings can't do it because human language is actually a product of imagination), we will draw a line on the ground and say that this is called a national border, and we will invent symbols called words, which means that human society can rely on this imagination to unite and form tribes and even countries. There is a career differentiation and the pursuit of survival outside of it.

The fundamental differences between modern apes and humans are mainly as follows: (1) different modes of movement Apes are mainly arm-walking; Humans, on the other hand, walk upright (2) Different abilities to make tools Great apes can use natural tools, but they can't make tools; Humans can make and use a variety of simple and complex tools (3) Different degrees of brain development The ape brain has a capacity of about 400ml and has no ability to speak and write; The capacity of the human brain is about 1200ml, and it has strong thinking ability and language and writing ability The most fundamental difference is the generation of language and consciousness, and humans have the ability to speak and write, while apes do not

Therefore, d

The three changes in modern people are the future direction of human evolution, what will they look like in the future?

Biological evolutionThe sign is in the populationGene frequencyof changes. There are many reasons for changes in gene frequencies in natural populations, including migration in and out, but the hallmark of biological evolution is the change in gene frequencies in populations.

Before the advent of near-coarse ortholithic science, the development of evolutionary thought was slow, and creationism and species invariance were widely prevalent at that time. This view remained dominant in biology until the 18th century, and its exponent was Sweden.

Botanist Linnaeus.

Although his proposed classification system helped to uncover the historical connections between biological species, he regarded species as immutable products of God's creation. With the development of production and science, many new facts have accumulated that contradict the immutability of the species.

History of biological evolution

The Earth is located in the solar system.

A special vantage point that gives birth to a lot of life. From bacteria to single cells, from single cells to complex life, the journey between has carried 4.6 billion years of Earth's history.

Species evolution plays a major role in this. Evolution, also known as evolution, in biology refers to the change of genetic traits in a population from generation to generation.

The so-called trait refers to the expression of genes, in the process of reproduction, genes will be replicated and passed on to offspring, mutations in genes can change traits, and then cause genetic variation between individuals.

New traits are transferred through the population as the genes move through the population due to species migration or horizontal gene transfer between species. When these genetic variations are subject to non-random natural selection or random genetic drift.

Influences, when they become more common or no longer scarce in a population, indicate that evolution has occurred.

The evolutionary process of human beings can be divided into four stages:

1) Early ape-man stage: lived about 3 million to 1.5 million years ago, and already had the basic characteristics of humans, able to walk upright, and make simple gravel tools.

2) Late ape-man stage: about 2 million to 300,000 years ago, the body is like a man, the brain is larger, can make more advanced paleolithic tools, and began to use fire, such as Zhoukoudian in Beijing, China.

Peking Man.

3) Early Homo sapiens (hominal) stage: 10-200,000 to 50,000 years ago, gradually detached from the characteristics of apes and very close to modern humans, such as Neanderthals in Germany.

4) Late Homo sapiens (new man) stage: About 4-50,000 years ago, the evolution of human beings at this time showed a significant acceleration, and they were very similar to modern humans in form, and culturally, there were already the art of carving and painting, and ornaments appeared. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered.

At this time, primitive religions had already arisen and had entered a matriarchal society.

In the late Homo sapiens stage, modern humans began to differentiate and form, and spread throughout the world.

I think that people are developing in a better direction now, this era is progressing, and people's lives are gradually getting better, and this is the most obvious change.

In the past hundred years, our life has become better and better because of the strength of the motherland, since the founding of the Communist Party of China in 1921, let us break away from that feudal society, the founding of the Communist Party of China, to the Chinese who were in a period of national crisis brought hope and light, but also to the country brought a earth-shaking change, let China be reborn, laid the foundation for our beautiful life today, those heroes who fought on the front line of the times, won us the stable life we are now. They are the heroes of our people, the heroes of our country.

Recently, I watched the TV series "Awakening Era", which made me deeply feel how heavy the patriotic heart exuded by those people in that era, they are always fighting for the awakening of the motherland, and they can dedicate their lives for their country, such as: Mr. Li Dazhao used his life to wake up those who are desperate for their lives, so that they have hope for this era, and fight for it to revolution, he used his life to influence the people around him. Another example:

Chen Duxiu used the knowledge of the new culture of "New Youth" to alert all people in this era, and always adhered to the revolutionary spirit of anti-imperialism and anti-feudalism. They have transformed this nation with their actions.

Therefore, I think the most obvious change that has occurred in the past 100 years is the change of the country and the people, we have changed from the era when we could not guarantee food and clothing to the era when we are now living with abundant food and clothing, we have changed from the era of continuous war to the era of peace and warmth, from the time when we can't afford to eat or wear clothes to the rice and pasta that we eat every meal, and we wear beautiful clothes and enjoy the happy life that this era brings us, this is the biggest change. This era has given us all equal lives.

The discovery of interstitial organs, the increase in lifespan, the early adolescence, the decrease in body temperature, the increase in height, this is a very obvious evolution.

The obvious evolution is that people's facial features are becoming more and more delicate and three-dimensional, and the most important thing is that human thinking is becoming more and more agile, and life is getting better and better, and it is no longer the era when you couldn't afford to eat and wear warm clothes.

For example, human beings are becoming more and more civilized, and their quality has been improved, and science and technology have also been progressed and developed, and various electrical appliances and various high-tech products have also appeared, and the standard of living is also constantly improving.

The hallmark of the evolutionary level of the anthropogenic species is ().

a.Live together. b.Wisdom.

c.Worker-activated tools.

d.Lifestyle.

Correct Answer: c

Summary. Dear <>

We'll be happy to answer for you. The evolutionary process of human beings can be divided into four stages: (1) Early ape-man stage:

It lived between 3 million and 1.5 million years ago, and already possessed the basic characteristics of humans, such as being able to walk upright and make simple gravel tools.
