Orangutans are on the verge of extinction due to the loss of forest area and rampant illegal hunting.

The five-year study provided the first comprehensive observation of 634 known primates in the world. Studies have shown that the main threats to primates come from the destruction of their habitats by fires, the reclamation of tropical forests, and illegal hunting due to food and illegality.
Mitter Meyer Russell, chair of the IUCN Species Conservation Commission's Primate Expert Group, said the data we now have shows that the situation is worse than we thought. In Vietnam and Cambodia, about 90 percent of primates are considered at risk of extinction; In Africa, eleven of the thirteen species of red colobus monkeys are considered "endangered".
According to the study, two primates may have become extinct. Thus, despite occasional anecdotal anecdotes, there has been no sign of the creature since primatologists observed the "Miss Wharton red colobus monkey" in 1978.
Richard Longhan, president of the International Society of Primates, said: "Among the primates in Africa, large apes such as gorillas and bonobos are usually noticed, but small primates like colobus monkeys may be the first to disappear. ”
According to reports, human understanding of primates and their role in ecosystems continues to improve. Since 2000, fifty-three previously unknown primates have been discovered, of which forty-two are from African countries such as Madagascar, three from Asia, and eight from Central and South America.
The study highlights that Brazil's black lion tamarins and golden lion tamarins, which were removed from the list of "endangered" or "severely endangered" species in 2003, "are the only hope in the dark", thanks to the work and efforts of many relevant agencies over the past three decades.

There are three fundamental reasons: 1. Humans hunt and kill a large number of people, and the population size is reduced (hunting for food, hunting and selling). 2. Habitat is severely damaged and living space is reduced (deforestation, forest reclamation).
3. The natural environment is seriously polluted and cannot adapt to environmental degradation (air pollution, acid rain, chemical poisons).

Half of the primates are endangered, and only 900 mountain gorillas remain in the wild!

It's not that the intelligent apes are extinct, it's that these intelligent apes have evolved over millions of years and slowly become the humans we are today.
The ape-man is considered to be the direct ancestor of humans, with the dual physiological characteristics of humans and apes, and lived about 2 million to 340,000 years ago. The ape-man skull is low, the brow spine is prominent, and the teeth are large, which has the intermediate nature of ape and man. They were already able to make stone tools and were the first to make tools.
Ape man can be divided into early ape man and late ape-man.

Just because the pig species is not extinct, you don't have an answer to this question.

Modern archaeological speculation includes modern humans, with a total of 8 evolved into ape-humans (represented by Neanderthals), 2 of which perished naturally. The remaining 6 are estimated to have been destroyed by modern human ancestors (Homo sapiens). (The Peking ape and the cave man live together, and there is a difference of 30w years before and after, which is worth scrutinizing) gene said that modern humans contain a very small amount of Neanderthal genes, but unfortunately there is no verification of whether there are genes of Peking ape.
Modern humans (Homo sapiens) coexisted with cavemen for a long time (at least 1w years) before they left Africa. During this time, modern people were bullied (the population has always been around 1000 people), except for intelligence plus points, everything else (strength and speed**) is not as good as cavemen, this may be the reason why humans build houses on trees, most of the continent is the territory of cavemen, and Homo sapiens only have a small space by the sea. The relationship between cavemen and Homo sapiens is not the relationship of the territory of the animal kingdom, but the relationship of enemies (cavemen are also intelligent, can think, can use fire, and can make stone tools).
Finally, during the Ice Age, a large number of cavemen died, the technology tree of Homo sapiens was basically completed (it is estimated that the intelligence comparison is equivalent to 18 years old to 10 years old), Homo sapiens multiplied in large numbers (began to be riotous), and went out of Africa in large numbers three times, gradually from the sea to the inland, just to completely annihilate the enemy and take revenge for the original bullying.
Humans are a species that specializes in brain evolution. In other words, except for the brain, our other abilities are far inferior to those of animals in other evolutionary directions. The mass extinction of the ancient apes was precisely the crisis of the evolution of the brain's specialization, and before the invention of advanced tools, intelligence was far less effective than physical strength and speed.
The main reason for the extinction of the ancient apes was the sudden arrival of several ice ages, and the sudden cooling led to the mass extinction of non-cold-tolerant animals. Although the ancient apes were already able to use sticks and stone tools, they could not use fire or make clothes. Paleoanthropoids, lacking fur on their bodies, were not adapted to cold climates.
In addition, as ancient apes living in groups, they had to be in sufficient numbers to effectively drive away cats and defend their territory and food. The lack of food caused a large number of ape populations, and finally it was turned into a vicious circle of winter food for large cats that were more adapted to cold climates, and finally completely wiped out.

From about 100,000 to 50,000 years ago, there was some kind of significant change in the abilities of our ancestors. The Great Leap Forward raised two major unresolved issues, namely, why it was triggered and where it occurred. ......As for the question of where the Great Leap Forward took place, did it take place in a certain geographical area, among a certain group of people, so that they could expand their sphere of influence and replace those who had previously been in the rest of the world?
Or is it happening in different regions at the same time, and the people who live in each of those regions today may be descendants of those who lived in the region before the Great Leap Forward? The skulls of humans, some 100,000 years ago, excavated in Africa and quite modern, have been used to support the former view that the Great Leap Forward clearly took place in Africa. Molecular studies (of so-called mitochondrial DNA) were also initially explained by the modern claim that they originated in Africa, although the implications of these molecular discoveries remain questionable.
On the other hand, the skulls of people who lived in China and Indonesia millions of years ago are believed by some physical anthropologists to show features that can still be found in modern Chinese and Aboriginal Australians, respectively. If this is the case, then this finding may indicate that the parallel evolution of modern humans and their origins in multiple regions, rather than in a single Garden of Eden, remains unresolved. The strongest evidence for the assertion that modern man originated in one locality, then spread outward, and later replaced people elsewhere seems to be in Europe.
About 40,000 years ago, the Cromanus entered Europe with their modern physique, excellent ** and other advanced cultural features. Within a few thousand years, the Neanderthals ceased to exist, although for thousands of years they had been living on the land as the only inhabitants of Europe.o This result strongly suggests that the modern Cromenus somehow used their far superior technology and their linguistic skills or intelligence to infect, kill, or replace the Neanderthals with germs, with little or no evidence of a mixture between Neanderthals and Cromenus. This Great Leap Forward coincided in time with the first confirmed major expansion of human geography since our ancestors settled in Eurasia.
This expansion included the occupation of Australia and New Guinea, which at the time were still joined together to form a continent. <>

There are only two reasons for the extinction of a certain organism, either it is the extinction due to the inability to adapt to the change of the environment, or the extinction caused by human activities. "Ape-man" is an animal between ape and man, they may be the ancestors of humans, in the process of evolution, under natural selection, the survivable individuals are constantly retained, and those with poor viability are constantly eliminated. Because in the process of evolution from apes to humans, they have been living in the same environment, with limited survival resources, and more intelligent and competitive individuals continue to appear, resulting in the descendants of apes, those who are weak in competition and not smart enough are constantly eliminated, it is in such a generational elimination mechanism, and finally human beings appeared, and human apes were gradually replaced by humans, so, apes became extinct.
Therefore, it can be understood that the apes evolved, and it can also be considered that they could not adapt well to the environment and were gradually replaced. The environment in which orangutans live is different from that of humans at that time, and they do not affect or interfere with each other, so orangutans are not extinct.

This is a false proposition, the ape-man did not become extinct but evolved.
-
The ape-man should have mixed with the primitive man and the difference was very small, and after a few intermarriages, they became one.

It took millions of years for ancient apes to evolve into modern Homo sapiens, and a wide variety of ancient apes were born from them, and although these ancient apes were not as intelligent as Homo sapiens, they were also smarter than orangutans!
Why haven't the orangutans disappeared until now, while the other australopithecus didn't coexist with Homo sapiens and all disappeared?
The competition for mates is a protracted and long-term war between the old and new Australopithecus, and the female old apes are constantly being plundered by the new Australopithecus, and a large number of male old apes have lost the right to mate. It is important to know that the life of Australopithecus was social rather than dispersed, and once a colony is defeated, all females will be plundered. Male australopithecus without females will either fight for the rest of their lives or bully weaker groups.
It's a winner-takes-all game, and the loser will be alone with his right hand for the rest of his life.
Hunter-gatherers were the way of survival of Australopithecus, and the newly evolved Australopithecus were more powerful hunters than the old ones. Even if the male Australopithecus is not killed by the Neoaustralopithecus, its territory and food will be constantly contested and squeezed by the Neoaustralopithecus.
The old apes were already very difficult to survive because of the competition and squeezing of the new ones, and if they encountered major environmental disasters such as ice ages, giant volcanic eruptions, and asteroid impacts, the old apes would quickly become extinct. Extreme weather is like a limit test for the survival of species, and it is extremely lethal to both old and new apes, depending on who has more resources in their hands and who is more resilient to disasters.
According to DNA analysis, the number of modern Homo sapiens plummeted to a few thousand during the worst of the climate, but fortunately survived. The old apes were vulnerable to extreme weather and could go extinct suddenly.
Orangutans have no reproductive value, orangutans have no hunting value, and orangutans have no conflict of interest with apes.
Summary:Orangutans have no fertility value or hunting value for ancient apes, and they can also avoid river water with ape-man well water, so they are spared.

Chinese people are all over China.
There are two reasons that I know so far: , Tasmanian devils have a large territory and live alone, deforestation, habitat reduction, food reduction, and population decline The second is viral tumors, and 2 3 Tasmanian devils have died of this rare facial tumor, but scientists have not yet found the cause and method of this disease.
According to the research of scientists, the earth has existed and operated for billions of years, the internal biological chain has matured and stabilized, and endangered plants are also a link in the entire biological chain. >>>More
Among the reasons for the extinction of sloths is the destruction of the ecological environment caused by human deforestation, the food of sloths decreases, and the number of sloths begins to decrease.
