Why did Homo sapiens replace Homo erectus?

From a practical point of view, it was Homo erectus in Asia and Europe that evolved into Homo sapiens, so Homo erectus in these places does not exist, you look at Africans, they are now Homo sapiens, can that place be advanced into Homo sapiens. I knew that our family was Homo sapiens Asian, not African.

To put it simply, it is estimated that it is tiring to look at it if it is too long to write 1 Homo erectus has a small population Homo sapiens is endless, 1 It has been assimilated by mixed blood, such as the Xianbei and Han mixed bloods have disappeared 2 It has been extinct by reproductive isolation, such as 100 horses and 10 donkeys, and the donkeys will become extinct after a long time 3 The living conditions in Europe during the ice age were harsh, and Homo erectus did not form a large group For a long time, the marriage of close relatives in small families The result is tragic For example, many royal families have been related to each other for a long time, and the life expectancy of offspring is getting shorter and shorter, and there is a genetic disease. 2. Homo sapiens has a high IQ, is good at manufacturing and using ** equipment, has high storage and logistics capabilities, is internally united, organized and disciplined, has developed limbs, but has a developed mind, and has poor ability to adapt to the environment, has not survived the fourth glacial period, lacks food and clothing. III. It is possible that Homo sapiens brought new viruses and bacteria that were beyond the resistance of Homo erectus.

First, the nature is different.

1. Homo erectus (Latin scientific name: Homo erectus), ancient humans who lived in Africa, Europe and Asia 1.8 million 300,000 years ago, it is generally believed that Homo erectus originated in Africa.

2. Homo sapiens (scientific name: Homo sapiens) is the only extant species under the genus Homo. The morphological characteristics are more advanced than those of Homo erectus.

Second, the morphological characteristics are different.

1. Homo erectus: they already have the characteristics of a human being: they can make tools and walk upright, but they have a small brain volume (1000 ml) and their heads still retain more primitive properties.

The living age is about 2 million to 200,000 years ago, which belongs to the early Pleistocene to the early Pleistocene in geology, which is equivalent to the early Paleolithic in archaeology.

2. Homo sapiens can distinguish itself from other living apes by having a significantly enlarged brain, relatively reducing most of the body's hair cover, and having a series of bones and muscles that can adapt to the habitual bipedal movements, including foot structures that have lost the ability to grasp.

It is a terrestrial biped with limited ability to swim and dive and must be learned. Exhibits strong changes in body size and proportions, as well as pigmentation, some of which may be related to the wide range of environments in which Homo sapiens lived. Exhibits moderate sexual dimorphism in body shape.

Habits

Homo sapiens are opportunistic omnivores that have shown remarkable ingenuity in extracting, producing, processing, and preserving food. Homo sapiens is the only species that can be controlled or **, and all known extant populations of Homo sapiens are cooking. Regional differences in diet are influenced by availability in specific contexts, cultural traditions such as food preferences and avoidance, and genetic factors.

The persistence of lactase allows some Homo sapiens to consume milk and dairy products throughout their lives, a recent adaptive adjustment to dairy consumption that will only play a role in Homo sapiens with a tradition of dairy farming.

There are several reasons why Homo sapiens might be afraid of Homo erectus:

1.Superiority in strength: Homo erectus generally has greater physical strength and strength than Homo sapiens, which gives them an advantage in certain situations, such as in combat or hunting. Homo sapiens may feel intimidated when confronted with Homo erectus' superiority in strength.

2.Hunting Competition: Since Homo erectus may have been more proficient in hunting skills and strategies than Homo sapiens, it may pose a threat to Homo sapiens' hunting activities, causing Homo sapiens to be fearful of them.

3.Survival Competition: If Homo erectus survives in a similar way to Homo sapiens, and there is competition for certain resources, such as food, water, or territory, then the presence of Homo erectus may cause stress and fear to Homo sapiens.

4.Fear of the unknown: Since Homo erectus may behave and think differently than Homo sapiens, Homo sapiens may develop a fear of the unknown. This fear of the unknown may have caused Homo sapiens to feel uneasy and frightened when encountering Homo erectus.

It is important to note that this fear may be based on an instinctive reaction between species and does not necessarily represent an actual threat or danger to Homo erectus to Homo sapiens. In fact, Homo erectus and Homo sapiens may have complemented each other in survival skills and intelligence, and they may have also interacted and cooperated to some degree.

Homo sapiens was afraid of Homo erectus

1. Homo erectus is ferocious and powerful, and Homo sapiens is stronger than Homo erectus in strength.

2. Homo erectus runs faster than Homo sapiens, and Homo sapiens may be chased by Henghuai gear. Homo sapiens, also known as humans, is the only living species of the genus Homo sapiens, with more advanced morphological characteristics than Homo erectus.

Neither evolution nor substitution, it's the same level, it's just that we named ourselves Homo sapiens. They belong to different species.

It's all evolving, but there's no substitute for it.

Let's replace the relationship, Homo erectus has a simpler mind, while Homo sapiens has a richer mind.

Let's replace the relationship, except that Chileans have lower intelligence, while Homo sapiens have higher intelligence.

It is a substitution relationship, only one has wisdom and one has lower wisdom.

There should be no substitution, but it's all evolved.

It is both evolution and substitution, and the two types complement each other.

A mutually reinforcing relationship that depends on each other to grow.

I really don't know what the relationship is.

Each is its own and has nothing to do with the other.

Human Ancestor A: "Let's go, let's go hunting monkey-headed apes and come back to eat, what's going on?" "Human Ancestor B:

Okay, let's go fight the monkey-headed ape and come back to eat! After a long time, human ancestors A and B each came back from beating the monkey-headed ape, killed the fire and roasted it! After a full meal and wine, the ancestor of mankind A:

Hey, why does this monkey-headed ape skull look a little like us? Human Ancestor B leaned over and looked at it carefully: "Hey, it's really a bit like that!"

Human ancestor A and B thought about it for a long time, but couldn't think of any reason! Human Ancestor A: "Kill the monkey-headed ape, it will take revenge, leave them a few stone tools after leaving the cave and ask for forgiveness!"

The two ancients developed independently, and there is no substitution relationship.

It can't be said that Homo sapiens is divided into early Homo sapiens and late Homo sapiens, and at the same time includes many subspecies. Except for modern man, everything else is extinct. Modern humans must belong to the late Homo sapiens.

The Great Migration from Africa began roughly 40,000 to 60,000 years ago. Other Homo sapiens who came out of Africa earlier became extinct, probably by our ancestors. There are many theories of extinction, some are fusion, some are food shortages caused by ice ages, and some are difficult to survive, and there are also theories that modern humans are unable to compete and are driven to a harsher environment and lead to extinction.

It can be caused by a combination of factors.

1.Origin of Homo erectus and Homo sapiens.

Homo erectus refers to humans in the early stages of human evolutionary history, when the body structure began to develop in an upright direction, mainly in Africa. Homo sapiens, on the other hand, is a human population formed by a high degree of intellectual development on the basis of Homo erectus.

2.Body structure of Homo erectus and Homo sapiens.

Homo erectus had a stronger body frame and a thicker skull than Homo sapiens. At the same time, the brain volume of Homo erectus is also relatively small, and the arches of the eyebrows and cheekbones are more prominent. Homo sapiens, on the other hand, had a relatively thin skull and a larger brain capacity, while the arches of the eyebrows and cheekbones gradually disappeared.

3.Culture and lifestyle of Homo erectus and Homo sapiens.

During the Homo erectus period, humans began to use simple tools such as stone tools and torches, and lived in the stage of gathering and hunting. With the continuous development of intelligence, the Homo sapiens group began to make more complex tools, and developed agriculture, forming feudal societies and urban civilizations.

4.Homo erectus and Homo sapiens were adaptable to their environment.

Homo erectus originated in the savannah region of Africa and was relatively adapted to this environment. And as humans evolved, Homo sapiens had a wider ability to adapt to the environment, adapting to different climates and geographical environments. Sincerely.

5.Genes of Homo erectus and Homo sapiens.

The DNA gene sequences of Homo erectus and Homo sapiens are different, with Homo erectus having a relatively simple genetic sequence, while Homo sapiens has a more complex genetic code. This also indicates that Homo sapiens has been more genetically advanced.

6.Species competition between Homo erectus and Homo sapiens.

With the emergence and development of Homo sapiens, the population of Homo erectus gradually declined and eventually disappeared. Homo sapiens replaced Homo erectus as the best and most intelligent species on the planet.

In summary, there are significant differences between Homo erectus and Homo sapiens in terms of physiological structure, lifestyle, environmental adaptability, and genetics. Homo sapiens outcame the competition with Homo erectus and became the most powerful intelligent species on Earth. However, the evolutionary process of human beings continues, and we should also cherish what we have and keep moving forward.
