What creatures evolved from man

Humans are transformed from single-celled organisms.

Most of the animals on land today come from water to land. In the history of the Earth's evolution, the Earth was once a water ball, and the earliest life forms on Earth were born from water. Humans share many similarities with other aquatic mammals.

Some scientists believe that early humans lived in water.

According to the Gondwana continental theory, about 8 million years ago, there was an ape-like arboreal animal known as the closest common ancestor of modern humans and apes, and they lived in the dense forests of Africa. Later, the offspring of this animal split into two branches and went their separate ways, one evolved into a human primate, while the other remained in the forest to become a modern ape.

However, a new scientific discovery has made this theory difficult to justify: the African savannah appeared after humans learned to walk on two feet.

What theories could explain the parting of the ways between man and ape? Some scientists believe that the tree apes came down from the trees and came to a flat habitat, not flat land covered with soil and grass, but in water. Early humans lived for nearly a few million years, and before they went to land, they lost their hair and evolved their own unique characteristics, a view called the "Ahuizotl theory".

It was proposed by Elena Morgan, a female scholar who won an award for her book "The Ahuizotl Hypothesis".

Morgan points out that most early human fossils were found in water-covered areas or at the water's edge in prehistoric times, with many fossils of crocodile eggs and crab shellfish also found near the site of the most famous human fossil, Lucy, known as Eve.

Morgan also pointed out that there are many biological similarities between humans and aquatic mammals such as dolphins, hippos, and walruses, one of which is subcutaneous fat, which acts like a thermal blanket to prevent body heat from being lost quickly underwater, because water absorbs heat faster than air. Most terrestrial mammals, including our closest relative, apes, do not have this layer of subcutaneous fat, instead they have a thick layer of hair. Humans and aquatic mammals have little or no hair.

Morgan argues that there are many characteristics of life in the water

1.The nostrils are facing down rather than upwards so that water does not enter the nasal passages while diving.

2.The human body needs iodine and 2 3 fatty acids, which are important nutrients for brain development, which are very rare in food on land, but have a lot in fish and shellfish.

3.Humans are covered by many sebaceous glands, which secrete an oily fluid called sebum to make the hair and sebum smooth, while apes have almost no such sebaceous glands.

There is also some corroboration to the theory that humans originated from Ahuizotl. Scientists once found a well-preserved dried mermaid corpse in an indigenous tribe, which, according to locals, was captured by their ancestors while fishing at seaMany people also believe that mermaids are not just a beautiful legend, but a branch of the ancient apes that evolved in the water and eventually became extinct due to environmental changes.

To put it simply, humans evolved from creatures of ancient times. If you want to sort out the evolutionary history of human beings, it is like this, from the beginning to the present: human pioneer species, Sibrano man, Homo erectus, artisan, Flores, Gaudeng man, homo genus Georgia, homo homo, homo heidelberg, Neanderthals, homini Rhodes, homo Rudolphus, homo sapiens idatu subspecies, modern homo homo.

Single-origin and multi-origin theories of human beings: The single-origin theory holds that modern Homo sapiens evolved in Africa 200,000 years ago. Homo sapiens began to migrate out of Africa between 70,000 and 50,000 years ago, eventually replacing hominid species that existed in Europe and Asia at the time.

This theory has been supported in recent years by genetic, linguistic, and archaeological evidence. The multi-origin theory holds that human beings did not originate in Africa alone and that human evolution is global, but this theory has not yet found genetic evidence to support it.

Man evolved from apes.

In the evolution from ape to man, social activities played an important role, including social labor and the interaction between different individuals in the process of labor. Through the way of life such as gathering and hunting, complex forms of group organization were established. The social relationship of close interdependence and division of labor and cooperation between individuals in the group has been established, and an increasingly complex social organization has been established.

At the same time, language is needed for social activities, and language is used in all aspects of life, and writing is gradually developed, which promotes communication and exchange between people. At the same time, on the basis of language, there is a social culture, and the use of language and writing plays a crucial role in the evolution of the brain.

In the process of primate evolution, organisms are in an increasingly complex social structure, survival experience is accumulated and transmitted through the group from generation to generation, and the complex individual relationships in the group produce various physiological and psychological experiences, all of which promote the perception and cognition of life for nature and self.

Through the influence of complex behaviors and social activities, primates gradually distanced themselves from ordinary animals in terms of intelligence, and embarked on the road to a higher form of life.

Complex social activities have created human culture, which in turn has promoted the formation and development of human intelligence. It has taken a long time from the evolution of primates to humans, and this process is also the process of the development of primate intelligence, or the accumulation process of life's knowledge of nature and self, and the rapid development of intelligence is the key factor that contributes to the differentiation of some primates from ordinary animals.

Humans evolved from apes!

The evolution of humanity is divided into four stages.

Stage 1: Early ape-man, between 2 million and 1.75 million years ago, able to walk upright and use the simplest stone tools.

Stage 2: Late ape man, 1.75 million to 300,000 years old, specifically Yuanmou man, Peking man and other earlier ape man, more agile and flexible, know how to use fire, live in groups, and can build more exquisite stone tools.

Stage 3: Early Homo sapiens, 300,000 to 50,000 years ago, including Maba and Neanderthals, etc., most of them are close to modern humans, but there are still a few ape-man characteristics (protruding mouth, etc.), which can produce simple tools, hunt wild animals, and know how to make fire artificially.

Stage 4: Late Homo sapiens, 50,000 to 10,000 years ago, specifically the cave man and the Cro-Magnon, etc., the brain capacity is equivalent to that of modern humans, the appearance characteristics and body are similar to those of modern humans, can make more complex stone tools, horn tools, backbones, etc., know how to make simple ornaments, can sew clothes and build tents, etc.
