Humans were monkeys 3 million years ago, a fish 300 million years ago, and a bacterium at the earlie

Scientific studies have shown that the earliest life on Earth came from single-celled organisms in the oceans, so there is no problem in expressing human beings on a macroscopic scale.

That's no problem at all, it's like bacteria can form worms. If you get a good environment, then bacteria can completely evolve.

The ancestors of humans were apes. According to Darwin's theory of evolution, the ancestors of human beings were ancient apes, and after natural selection and genetic recombination and mutation, ancient apes evolved into the appearance of modern humans, and in the process of evolution, they learned to think, learned to make tools, and experienced changes in brain capacity, so they were born with wisdom, have the ability to think, and gradually become the overlord of the earth.

The history of the development of apesApes are mammals, large in shape like monkeys, of many types, without buccal sacs and tails, and some of the characteristics are similar to those of humans. A common name for the primate ape family, which includes two families. Although apes are often referred to together, monkeys are sometimes referred to as apes, and apes are sometimes referred to as monkeys, but they are biologically different animals.

The main difference between the two is that monkeys have tails, while apes do not.

Taxonomically, man is a type of ape. Early apes began to emerge about 25 million years ago. Modern apes appeared 18 million years ago, orangutans appeared 14 million years ago, gorillas appeared 7 million years ago, and humans and chimpanzees appeared 300-5 million years ago.

Mammals, similar to monkeys, larger than monkeys, have no sacs under their cheeks, no tails, orangutans, gorillas, gibbons, etc.

The bacteria of 3.8 billion years ago and the fish of 300 million years ago were only the ancestors of humans, and the bacteria and fish of that year were only a part, and they evolved to more advanced animals, and then slowly evolved into humans, and the rest of the bacteria and fish are still left to the present, so they have not evolved so far.

Because evolution requires not only a long period of time but also a suitable environment, the ancestors of human beings moved from the sea to the land, and then walked from the trees to the ground, freeing their hands before gradually evolving into modern humans, while fish have always relied on water for survival, and bacteria also need hosts, so there is no special evolution.

First of all, this statement is not entirely correct, we humans and bacteria, fish do not have the relationship of ancestral descendants, the origin of human beings is apes, not bacteria and fish. For hundreds of millions of years, fish and bacteria have been evolving in their favor, not in the direction of humans, so it would be wrong to say that they have not evolved to this day.

It is a great mistake that it is a branch of primates that evolved into humans, and no scientist has ever said that humans evolved from monkeys. It's just that modern evolutionary theory has roughly mapped out the evolutionary history of life on Earth, and the origin of life can be traced back to marine single-celled organisms.

The statement that human beings evolved from the post-monkey is mainly based on the slander of Darwin by some conservative forces in the Darwin era, in fact, Darwin himself did not say this, and Darwin's "Origin of Species" does not have this statement, Darwin only saw the possible connection between humans and some species from the similarity of species, diversity and the connection between the environment and biological traits, etc., but what Darwin could see in the era is this kind of more superficial information.

Modern scientists have roughly determined the evolutionary process of human beings through phylogeny (a discipline that studies the laws of biological evolution and the genetic relationship between species), molecular phylogeny (tracing the origin of organisms at the molecular level), plus traces of human activities (fire, stone tools), etc., and the rate of gene mutation and the genetic diversity of people around the world can be traced back to the mitochondrial gene Eve and Y chromosome Adam, basically determining that human beings originated in Africa. However, it is not believed that humans originated from monkeys, but that one of the primates evolved over a long history.

Further evolutionary history, it can only be traced back to the origin of organisms through phylogenetics (upper and lower limb structure, upper and lower jaw structure), genetic information can basically no longer be found, many modern organisms do not have lower jaws, and humans have lower jaws, this bone structure is also difficult to create out of nothing, it is more likely that the structure and modern human different species evolved into modern humans, through the study of fossils, found stone salamanders and other primitive amphibians, they all have lower jaws, Moreover, they all have the same vertebral spine as modern reptiles and mammals, so they may be related to the origin of humans.

Further back, there is less evidence, mainly through tiny fossils, and the current fossil evidence shows that the earliest life on earth were microorganisms, so it can be generally determined that life on earth evolved from simple single-celled organisms to complex multicellular plants and animals, and if you trace the complete evolutionary history of humans, then it may indeed be traced back to microorganisms living in the ocean.

But things are developing, we can't say that the animals that have developed into multicellular are still single-celled animals in the ocean, it is obvious that the number of cells is not the same as that of single cells and multicellular, and the evolution of physiological functions is also progressive, the modern human body structure is complex, and it is definitely not a fish or a microorganism, it is one of the countless results of the dynamic evolution of biological evolution.

Humans evolved from apes, not monkeys, and monkeys and apes belong to the same suborder of primates. Australopithecus also evolved from small terrestrial mammals, and mammals are derived from fish in the ocean, and fish are single-celled animals from the ocean.

There is a certain scientific basis, but it is not absolute, the primates of 3 million years ago are indeed our ancestors, including the Devonian period 300 million years ago, mainly marine life, but the statement of bacteria is incorrect, the original form of any life is single-celled.

According to the theory of evolution and archaeological finds, so to speak. Because the earliest organisms on the earth were very simple, with the development and evolution of organisms, they gradually differentiated into the present diverse biological world.

No. If our ancestors were really a fish, then we should have been born to be able to swim, but the truth is that we were born with no swimming, so our ancestors were not fish.

The origin of human beings is a question that is still being explored to this day, and it is suspected that humans evolved from fish because of the similarities between humans and fish in the embryonic stage, and the ocean is indeed the birthplace of life, so it is understandable to suspect that it is fish, and scientists are still exploring, waiting for the day when the mystery will be revealed, maybe we did evolve from a special fish through a transitional species.

We weren't fish 300 million years ago. Three hundred million years ago, we were supposed to be single-celled organisms, and then we slowly evolved to the present.

300 million years ago, humans were really just a fish. Humans evolved from fish. There are many scientific discoveries that prove this.

It has been millions of years since the birth of human beings, and in the course of millions of years of development, human beings have become more and more powerful, according to Darwin's evolutionary point of view, the ancestors of human beings were apes, and through step by step evolution, they eventually became intelligent creatures, and there is today's development.

But there are still many doubts about Darwin's theory of evolution, maybe Darwin's theory of evolution is wrong, what is going on? There are many biologists who have questioned the theory of evolution, and some scientists have found that the ancestors of many species are the same when studying the species of the earth, such as mammals ** than oviparous reptiles, and oviparous reptiles ** than amphibians, amphibians ** in the ocean's earliest chordate fish ......

According to Darwin's theory of evolution, the ancestors of human beings were apes, and chimpanzees are our close relatives, but we may have been deceived by evolutionary theory, and human ancestors may not be apes. Biologists have observed the embryonic development of fish, turtles, chickens, pigs, cattle and other organisms, as well as humans, and found that the development and maturity of all species in the embryonic stage is a process of repetition of biological evolution.

But there is still a gap in the theory of evolution, humans were reptiles a long time ago, and fish had the ability to crawl a long time ago, and it is also a vertebrate, so fish have a close relationship with all existing terrestrial creatures. According to scientists' research on fish fossils dating back 300 million years, some of the physiological characteristics of fish and humans are still relatively similar.

It is understood that the genetic similarity between humans and chimpanzees has reached 96%, the genetic similarity with cats has reached 90%, and the genetic similarity with mice has reached 85%, these results show that humans and other species are likely to be the same ancestor, so our ancestors are not necessarily apes, it may be 300 million years ago fish, or it may be a single-celled organism.
