How many years has it been since the birth of mankind and how long has it been since the birth of ma

Based on fossil material of Australopithecus and hominin that has been discovered, the earliest humans may have been 3 million or 4 million years ago.

Australopithecus 3 million years ago.

Began to appear, about 1.5 million to 2.5 million years ago, one of the branches of Australopithecus evolved into Homo sapiens, about 2 million years ago, Homo erectus first appeared in Africa, the so-called late ape-man, knew how to use fire, began to use symbols and basic language, Homo erectus was able to use more refined tools.

Late Homo sapiens is anatomically modern man, which began to appear about 40,000 or 50,000 years ago. The main differences in the morphology of the two are the reduction of the anterior teeth and face, the weakening of the brow ridge, and the increase of skull height, which is more obvious in modern humans.

Early Homo sapiens:

Early Homo sapiens generally refers to humans who began to live in the late Middle Pleistocene more than 200,000 years ago and are morphologically between Homo erectus and Late Homo sapiens. Ancient Chinese humans such as Dali Man, Jinniushan Man, and Maba Man are generally classified as early Homo sapiens.

The Neanderthal Valley was the first to be taken seriously.

Found human fossils. Therefore, in the past, paleoanthropology used to refer to early Homo sapiens fossils as Neanderthals. Fossils from the early Homo sapiens (hominis) stage have been found in many parts of Asia, Africa, and Europe.

The Earth has survived for 4.6 billion years. Humans were born 5 million years ago. That is to say, 60 million years after the extinction of the dinosaurs, human beings were born, and humans were differentiated from the animal kingdom, and taxonomically, homo sapiens belong to the subphylum Vertebrates, Mammalia, Primates, Anthropoids, and Homo.

About 4.5 million years ago, humans and apes began to diverge, giving rise to Australopithecus ramanacus, which later evolved from Australopithecus australopithecus 2 million years ago, and then further developed into modern humans. Human is an umbrella term for human beings. Biologically, humans are classified into the general kingdom eukaryotic kingdom Eukaryotic subkingdom Zoological kingdom Posterior Mouth Animals Total phylum Chordates Vertebrate subphylum Amniotic general order Mammalian subclass Euzoomia subclass Primate ape suborder Narrow-nosed monkey suborder Homo sapiens subfamily.

Human beings can be defined on biological, spiritual, and cultural levels, or a combination of these definitions. Biologically, man is classified as a hominida, homin, hominid, a higher animal. On a spiritual level, man is described as being able to use the concept of a variety of souls that are believed in religion to be associated with divine power or spiritual immortality.

People:"Able to manufacture delicate tools, and be able to skillfully use tools for labor, have rich thinking ability, have the ability to judge that there is no conflict with the actual situation and conflict with the actual situation, have the ability to initially maintain the earth's ecosystem, have the ability to create and control the restoration"People should live in harmony with each other, and trust and communication are the most basic ways of survival between people. Evolutionary studies suggest that humans originated from forest apes and evolved step by step from primates through a long evolutionary process.

DNA and fossils prove that humans originated in Africa about 3 million years ago. Compared to other animals, humans have highly developed brains, complex abstract thinking, language, self-awareness, and problem-solving skills. The erect body structure of the human body allowed the human forelimbs to move freely, which allowed the intelligent human to master the use of tools far beyond that of any other species, and eventually developed great labor ability and creativity.

Man is a higher social animal.

At present, it is generally believed that the time when Australopithecus transformed into the first human ancestor was 7 million years ago. Judging from the human fossils that have been discovered, the evolution of human beings can be roughly divided into the following four stages: (1) Australopithecus stage.

Australopithecus australopithecus has been found to have lived between 4.4 million and 1 million years ago. According to the study of the anatomical features of fossils, the most important feature of Australopithecus from apes is their ability to walk upright on two legs. (2) Capable person stage.

Homo sapiens fossils have been discovered in Tanzania and Kenya in East Africa since 1960. The first Homo hoans existed 1.9 million years ago. Homo habilis is classified under the family Homo Habilis

Homo sapiens had significantly larger brains than Australopithecus australopithecus, and could use stones as materials to make tools (stone tools), which gradually evolved into Homo erectus. (3) Homo erectus stage. Homo erectus belongs to the genus Homo erectus, referred to as Homo erectus, commonly known as ape-man.

Homo erectus fossils were first discovered in 1891 in Java, Indonesia. At that time, there was also a debate about whether it was a man or an ape. It was not until the 20s of the 20th century that the fossils and stone tools of Peking Man were discovered in Zhoukoudian, Beijing, which established the position of Homo erectus in the history of human evolution.

Homo erectus lived from about 1.7 million years ago to more than 200,000 years ago. To date, Homo erectus fossils have been found in Asia, Africa and Europe. (4) Homo sapiens stage.

Homo sapiens is generally divided into early Homo sapiens (ancient Homo sapiens) and late Homo sapiens (modern humans).Early Homo sapiens lived between 200,000 and more than 100,000 years ago. Late Homo sapiens began about 100,000 years ago.

Its anatomy has been basically similar to that of modern humans, so it is also called modern humans in anatomical structure. Based on the fossil evidence of humans that has been found so far, Australopithecus is the earliest known human.
