Where do we humans evolve?

Modern people are different from animals in many characteristics, they form in evolution for millions of years according to different theories. However, there were still false doctrines and hypotheses and were later removed.

Where does human history evolve?

1. Know how to build tools

Anthropologist Kenneth Oakley once affirmed in a 1944 article 'it is the making of tools to help humans evolve'. He explained that monkeys already know how to use available objects such as sticks and stones as tools, which are considered the first human actions. In the early 1960s, Louis Leakey found traces of Homo habillis (skillful) dating back to 2.8 million years in East Africa. However, Jane Goodall and some other researchers point out that chimpanzees also know how to use sticks for certain purposes, such as removing leaves or catching fish.

Archaeologists are collecting stone tools considered by ancient humans.

2. The 'destroyer'

Anthropologist Raymond Dart said that our ancestors were considered 'destroyers' at the time - a predator using their power to catch other children, beat them to death and tear them to pieces. The piece with a hungry face satisfied the fresh blood thirst. This detail may only appear in fictional novels, but after catastrophic World War II, Dart's doctrine of 'destroyer' has been agreed.

3. Know how to share food

In the early 1960s, 'destructive' monkeys were replaced by 'friendly' monkeys (hippie ape). The anthropologist Glynn Isaac has unearthed evidence of the carcass being pulled to a place for the whole community. He said that sharing food leads to the need to transmit information about food places that can be found, and therefore, language - a characteristic social behavior of people is born.

4. Humans can swim 'naked'

Elaine Morgan, a documentary, said that humans evolved from primates in water and environment near water. Depilation helps swim faster as well as standing upright when wading. Hypothesis of the primordial spirit that had been abolished by the scientific community until 2013, David Attenborough proved it.

5. Know to throw stones to catch prey

Our ancestors began to evolve into people when the ability to throw stones at high speeds, archaeologist Reid Ferring said. He found evidence in Georgia about Homo erectus (the oldest human being, the oldest human-shaped human being), appearing 1.8 million years ago to use rock to catch prey. .

Before knowing how to make weapons, stoning was one of the hunting ways that ancient people used.

6. Hunting

Hunting creates opportunities for cooperation. Anthropologist Sherwood Washburn and CS Lancaster confirmed in an article published in 1968: in terms of intellect, hobbies, emotions and simple social life - all products evolved from the process. adapt to hunting. For example, the brain develops more in response to the need to store more information, while also leading to the division of labor between the sexes, requiring women to also seek food. This helps answer the question: why can women's brains grow so big?

7. Change food to have sex

More specifically, monogamous sex. According to a theory published by C. Owen in 1981: The important turning point in human evolution is monogamy six million years ago. Before that, the alpha man (leader) defeated all other opponents to get sex. The woman only had sex with a man, however, they liked the man who made a lot of food and stayed with her to raise their children.

8. Eat cooked food

To grow gray matter, the brain needs 20 times more energy than the muscle's energy needs. Researchers claim that humans cannot evolve if they are vegetarian, our brains begin to develop since we started eating meat about 2-3 million years ago, a source of protein and fat. And according to anthropologist Richard Wrangham, to digest cooked food, they have to use energy to chew, crush meat, which provides energy for the brain. When the brain has developed enough, people can make a conscious decision: eat vegetables, fruits and vegetables.

Cooked foods help the brain grow more.

9. Eat starch

The loading of starch into the body increases the size of the brain because the food is cooked with vegetables and some other starches are excellent food sources for the brain, more readily available than meat. Enzymes in saliva help convert carbohydrates into glucose the brain needs. Mark G. Thomas, an evolutionary geneticist, says: Human DNA contains many repetitions of amylase (which contains starch and glucose bonds), which make the brain breakthrough.

10. Go on 2 legs

Does migration from the tree to the ground and moving with two feet is a great turning point in the evolutionary history of mankind?

3 million years ago, Africa became hotter, forest area decreased, instead of the prairie landscape. To adapt, primates have to stand with two legs, from which, they can easily observe prey, while moving faster in the space of water and food sources apart from each other. However, the discovery of the Ardipithecus ramidus fossil skeleton (Ardi) dating back to 4.4 million years in Ethiopia poses a contradiction to the hypothesis: in a humid and woody area but Ardi still can go with 2 legs.

People are not the only species that can walk with two legs in the primates.

11. Adapting to the living environment

Richard Potts, director of the Smithsonian Human Origins Program, says: human evolution is affected by complex climate change. The emergence of Homo strains nearly three million years ago coincides with the extreme fluctuations between wet and hot dry climates. Through the natural selection process, primates can cope with unpredictable change and he also asserts that 'adaptability is a human characteristic'.

12. Unite and conquer

The anthropologist Curtis Marean points out a vision of human origin: an ultimate conqueror. After tens of thousands of years only limited to a single continent, humanity has been present globally. Why can they do that? The answer here is that cooperation is derived from conflict, not by mutual assistance . Cooperation of primates is a competitive advantage compared to rival groups, and they survive. Marean said that the combination of this unique tendency and advanced cognitive ability helps us adapt to the new environment, while promoting development, creating a premise for advanced missile weapon technology.

So what's wrong with these theories?

The above doctrines received much approval but still caused much controversy: humanity can be identified by a trait or group of characteristics, and each stage of evolution is a step. Important turning point on the path to becoming Smart Man (Homo Sapien).

However, humans do not evolve in a certain direction but are just surviving, adapting like Australopithecus or Homo erectus.

There are no characteristics that are considered a great turning point because the results are not known for sure. The turning points such as creating labor tools, hunting, eating meat, vegetables, cooperating, adapting as well as having big brains (human beings now) do not give us an accurate conclusion because in fact , until now, human beings continue to evolve constantly.
