Diverse ethnographic evolution
Humans have lived for tens of millions of years since the beginning of evolution.
If we go to the relevant historical records and scientific discoveries, I believe that most people will not believe in this long history.
Early humans not only had multiple human races, but were very different from today's Homo sapiens in both activity and social expression.
And now only Homo sapiens remain on earth, and regardless of which people of color, the genes in modern humans are surprisingly consistent, which of course has good and bad.
In terms of scientific research, a relatively small number of human racial genes could help scientists develop new drugs for human use.
On the downside, however, human genetic diversity is being tested today.
The difference between races is about 2% because the genetic similarity is so high.
This makes humans less resistant to disease, so that in the event of a mass epidemic disease outbreak, it often results in heaps of infected people appearing.
Yet the Earth had at least six other species of humans 100,000 years ago, but why are we the only ones left in the end?
Or why is Homo sapiens the only species left in the human family of the human family today?
In fact, there are very complicated factors regarding this issue, because it is not only unilateral reasons that lead to the shrinking of the human race.
Humans are the only creatures on Earth that have intelligence and are capable of basic productivity.
This makes us different from animals in that we can rely on our own hands to create and change the environment around us.
And in this long process, humans have experienced changes not only from environmental pressures, but also inter-racial strife.
There are also potentially other factors intertwined in the evolutionary history of humans.
Therefore, while discussing this issue, we cannot ignore the changes in the capabilities of Homo sapiens itself, as well as the changes that the environment has given back to humans.
In terms of human evolutionary history, the emergence of Homo sapiens was already 300,000 years ago.
In contrast, about 6 million years ago, the ape branch evolved into a species of the genus Homo.
Early humans discarded the long arms of apes and traded them for stronger legs.
Primates descended from the trees to the ground, which in itself is a very great evolution.
In terms of behavior patterns and range of activities, this gives humans the opportunity to reach out to a wider world.
And walking upright can help humans go farther, eventually moving away from the forest system and to the mainland.
About 2.4 million years ago, Noh appeared, and many research scholars agree that this was the first member of the genus Homo to evolve in apes.
Humans of this period were still relatively thin, weighing about 35 kg, and most of them would not exceed 1.2 m in height.
The most important point, of course, is that capable people made the most primitive tools through their hands.
These tools helped early humans to slaughter animals as well as make some relatively more elaborate items.
This life lasted for one million years, and then Homo erectus appeared.
Humans of the ancient times
As we can see from the name, this is the first known fully upright human species.
In proportion to the size of the apes, Homo erectus has shorter arms and longer and stronger legs compared to the torso, making it more suitable for long walks and runs.
The evolution of Homo erectus is also evident in their teeth, which are relatively detailed to help Homo erectus eat meat and digest proteins quickly.
This is more efficient in terms of increasing the body's energy supply, so in this respect, the brain of Homo erectus is larger than that of the average ape.
Scientists have also discovered in further excavations that Homo erectus was also the first human to learn to use campfires.
This suggests that humans in this period had learned to cook, and that consuming cooked food allowed humans to obtain more easily digestible food.
In this way, the brain receives more adequate nutrition.
Homo erectus has developed almost nine times as long as modern Homo sapiens has ruled the Earth.
In evolutionary terms, the emergence of Homo erectus marked the evolution of human beings towards a more efficient and excellent direction.
This was followed by the emergence of a large number of human species that began to appear all over the planet, and the emergence of Homo erectus enhanced the mobility of humans, which allowed our ancestors to go further afield.
The Rudolphs, the Heidelbergers, and the Frogs, these are all races of people who once lived on Earth.
But these human races are far less rich in comparison to their survival situation than several other human races.
Environmental closure was the more influential factor, during which the Earth experienced land plate changes, which separated a number of humans.
The timeline of human evolution comes to 400,000 years ago with the emergence of Neanderthals, perhaps the most powerful human species before the development and growth of the Homo sapiens race.
Neanderthals were much stronger, and the excavated fossil bones indicate that Neanderthals were in a long-term hunting activity.
The geographic distribution is mainly in the cold regions of Europe, Southeast Asia and Central Asia, so in terms of cold tolerance, Neanderthals have a greater ability to adapt to the environment.
In addition, archaeologists have found that Neanderthals were able to use more sophisticated tools and lived in complex shelters.
For example, they can use sewing needles made of bone to sew clothes as a way to help them withstand cold snaps.
Scientists believe that at least six other species of humans survived on Earth 100,000 years ago, and that Neanderthals did not fade into the history of human evolution until about 28,000 years ago.
So what factors have influenced the evolutionary changes in our ancestors that eventually left only Homo sapiens?
Homo sapiens survived as a result of the times, and not just in terms of their superior intelligence.
Paleoanthropologists studying the history of human evolutionary development say that what makes Homo sapiens different from other species is that only Homo sapiens created nations, religions, and languages.
In the activities of Homo sapiens, there is perhaps no other species as "aggressive" as Homo sapiens.
During the geological period from the Pleistocene (about 2.5 million years ago) to 10,000 years ago, ethnographic integration was an issue that could not be ignored.
Scientists have found in the genetic studies of modern Homo sapiens that modern Homo sapiens carry Neanderthal genes in their genetic makeup.
Interspecies hybridization suggests that the encounter between Neanderthals and Homo sapiens was no accident.
The interbreeding of Homo sapiens in Eurasia as well as Africa is clearly a valid proof of the increased range of Homo sapiens.
And researchers believe that the reason modern Homo sapiens have Neanderthal genes in their genes is that.
It may be the result of the detour of human activity back to Africa in the 20,000 years after modern humans mated with Neanderthals in Europe and Asia.
Ethnogenetic interbreeding may have brought an additional advantage in terms of speciation.
Homo sapiens lived in more groups than Neanderthals, in other words the Homo sapiens race was much larger.
This reduces the population reduction due to inbreeding and the overall better health of the population.
In further evolutionary competition, the developed brain of Homo sapiens brought a more advantageous competitiveness.
Studies have shown that although Neanderthals were higher in brain volume than Homo sapiens, they were less intelligent than Homo sapiens.
Excellent governance helped our ancestors create more sophisticated weapons, such as spears that could be thrown.
In contrast, although Homo erectus can also use tools, and hand axes used for more than 1 million years, but they are far less sophisticated than Homo sapiens weapons.
Eventually, in the competition of species, Homo erectus disappeared 30,000 years ago.
Darts, arrows, and throwable spears are all combat advantages that Homo sapiens had that Neanderthals did not.
The departure of Homo sapiens from Africa was a critical point, and the strong ability to create and survive gave Homo sapiens more ethnographic advantages.
It also accelerated the sixth mass extinction and continues to do so today.
The migration of Homo sapiens, the uncontrolled hunting, and the development of agriculture, among other things, led to population growth.
Further population growth created a demand for resources, which led Homo sapiens to drive out other species and to fight with them.
And after the initial formation of civilization, changes in language and social structure allowed Homo sapiens to be more competitive.
In the two hypotheses of Homo sapiens civilization (cultural intelligence and social brain), Homo sapiens could not have achieved what it has today without the creation of civilization, and the construction of society.
This was never shown in other races, and the development of intelligence further optimized the structure of the Homo sapiens race and helped Homo sapiens to victory in later ethnographic wars.
One of the changes in the environment can not be ignored, the ice age itself has made a number of human races disappear.
Only Homo erectus, Neanderthal and Homo sapiens were able to survive effectively in this period. But Homo sapiens won because it was more populous and had more resources.
In the end, in the game of evolution and elimination, Homo sapiens won the ultimate victory and other species were mercilessly wiped out and eventually became the remains of history.
And then in just tens of thousands of years, human civilization has come to the present day, and Homo sapiens is once again facing a new test.
