As early as many years ago, the archaeological community put forward the theory of multiple origins. Archaeologists have been arguing endlessly about the two theories of multiple origins and the same origin. The same origin theory means that humans originated in Africa, while many According to the theory of earth origin, although the African continent may have been the place where ape-man evolution first appeared.
But in fact, contemporaneous humans once appeared all over the world. It is only temporarily believed that the oldest human fossils were unearthed in Africa. There is no evidence to prove that there are no older human fossils in other regions. Whether it is multiple origins or the same origin, most scientists agree It is said that human beings evolved from ape-man, but in fact, in addition to the theory of ape-man evolution, some people have put forward the “water ape hypothesis”. At present, there are the following 7 views on the origin of human beings in the world.
The theory of evolution is currently the most widely accepted theory about the origin of human beings in the scientific community. According to the theory of evolution, humans originated in Africa and gradually evolved into modern humans through natural selection. This idea is supported by a wealth of scientific evidence, including the fossil record, genetic studies, and genetics.
Of course, the theory of evolution also has some doubts and controversies in the scientific community. Some people are skeptical of the theory of evolution, or propose some revisions or alternative theories to the theory of evolution. These questions mainly involve the following aspects:
First, the lack of intermediate fossils: Some people believe that the theory of evolution lacks sufficient evidence of intermediate fossils, that is, the lack of transitional fossils connecting different species. This is known as the “missing ring” problem.
Second, the origin of complex organs: Some believe that complex organ structures and functions cannot be explained only by natural selection and gradual accumulation. They believe that the origin of these organs requires the intervention of other mechanisms.
Third, the limitations of genetic mutations: It has been argued that the frequency and effects of genetic mutations may not be sufficient to support the evolutionary rate and diversity required by the theory of evolution.
Fourth, the issue of the origin of life: The theory of evolution focuses on the evolution of biological species, but the mechanism and process of the origin of life have not yet been fully explained.
However, it should be pointed out that these doubts do not negate the overall framework and core principles of the theory of evolution, but challenge the details and unresolved issues. The theory of evolution is still the most widely recognized scientific theory, which has been supported by a large number of empirical studies and evidence. The scientific community is constantly conducting research and exploration to resolve these doubts and further improve the theory of evolution.
The Landist view holds that humans originated in a specific location, such as Africa or Asia. This view is largely based on archaeological finds such as the Grand Canyon in East Africa and sites in the Middle East. Evolutionary evidence, however, suggests that humans originated in Africa and gradually spread to other regions over time.
3. The theory of multiple origins
The multi-place theory holds that humans originated in different places, rather than a single place. This view is largely based on the differences found in some human fossils, as well as the influence of geographical and environmental factors on human evolution. However, current scientific evidence favors the idea of a single origin.
Multi-place originism is the opposite view of evolution, which holds that humans originated in different places rather than a single place. However, the multilocale theory lacks scientific evidence to support it. The following are some of the main problems faced by multi-place origins:
First, genetic evidence: genetic studies have shown that the genomes of all modern humans share a common ancestor of African origin. Through extensive research on the human genome, geneticists have found that Africa has the richest human genetic diversity, and populations in other regions were formed after African humans migrated to other places.
Second, fossil evidence: The discovery of human fossils also supports the theory of evolution, that is, humans originated in Africa and gradually spread to other regions. The earliest human fossils, such as Lucy and Homo habilis, have been found on the African continent, and this fossil evidence corroborates with genetic evidence.
Third, archaeological evidence: Archaeological research also supports the idea of evolution. Archaeologists have revealed the evolution and migration process of humans in different regions through the excavation and analysis of ancient human sites. This archaeological evidence fits well with genetic and fossil evidence, supporting the idea that humans originated in Africa.
4. Biblical creationism
Biblical creationism is the religious belief that humans were created by God and that humans originated from Adam and Eve. This view is widely accepted in religious circles, but in the scientific community it is seen as a religious belief, lacking scientific evidence to support it.
5. Hybrid origin theory
The hybrid origin theory holds that humans originated in different places and crossed and mixed multiple times throughout history. This view is largely based on findings from archaeological and genetic studies, such as the genetic diversity of humans in different regions. However, the evidence for evolution still supports the idea of a single origin.
6. The Ancient Alien Intervention Theory
This view holds that humans originated from the intervention of ancient alien civilizations. However, there is currently no scientific evidence to support this idea, and it is based more on the supernatural or sci-fi imagination.
7. Intelligent Design Theory
Intelligent design theory believes that the origin of human beings was designed and created by one or more supernatural intelligent forces. This view is largely based on religious belief, but lacks widely accepted evidence in the scientific community.
It needs to be emphasized that the scientific community generally accepts the theory of evolution as the most reliable theory about the origin of human beings because it is based on a large amount of scientific evidence and research. Other views are largely based on religious beliefs, philosophical reasoning, or personal theoretical formulations, but lack the support of scientific evidence.
