The Origin of Humanity: What did humans evolve from?

Human evolution originated from forest apes and developed step by step from primates through a long evolutionary process.

It has gone through four stages: apes, primitive humans, sapiens, and modern humans.

Due to the development of today's archaeology, prehistoric civilization has been gradually denied, and archeology already has most of the evolving ancient ape fossils.

In line with current biological discoveries, it has been discovered that genetic DNA has evolved, confirming the authenticity of the theory of neutral evolution.

About 65 million years ago, a meteorite about 16 kilometers wide hit the Yucatan Peninsula in Mexico today, causing a huge disaster. At that time, two-thirds of the animal species on the earth, including dinosaurs, became extinct. Reptiles also became extinct.

At the end of the Golden Age, primitive mammals escaped disaster and survived for a long time, and then evolved rapidly.

About 50 million years ago, primates evolved rapidly in a radial manner. From the lower primates, the prosimians (such as lemurs and tarsiers), they differentiated into higher primates (that is, apes, such as

macaques, golden monkeys, baboons and apes).

(Note: China's Eonophythecus sinensis is older than the early higher primates apes and monkeys, and basically belongs to the early protosimians. That is to say, the so-called Eonophythecus sinensis is actually an ape, a branch of humans and apes.) 33 million -

24 million years ago, apes arose from Old World monkeys (suborder Stenorhini).

Protopithecus, the earliest ancient ape discovered in Egypt (30 million years ago); Egyptian ape (Aegyptopithecus, 26 million-28 million years ago) already has some characteristics of great apes; later fossils also include forest ancient ape, (2300

10,000 to 10 million years ago), it is widely distributed and has been found in Asia, Europe, and Africa.

The Protoconchorepithecus of East Africa (13 million to 12 million years ago) was already an ape and the ancestor of humans and African apes.

The above ancient apes are all forest-dwelling animals, walking on all fours and belonging to a group of tree-climbing apes.

Existing apes include two groups, African apes (gorillas, chimpanzees, and humans) and Asian apes (gibbons and orangutans). There is a clear boundary between these two groups. The differentiation of the two apparently occurred 12 million years ago.

-15 million years ago.

From about 10 million years ago to about 3.8 or more than 2 million years ago, there are two transitional fossil representatives.

One is Ramapithecus and the other is Australopithecus (many people believe that Ramapithecus is the ancestor of orangutans. In the past, there were deviations in the restoration of jaw fragment specimens and tooth analysis. Therefore, Ramapithecus is a transitional species.

Fossil representation has only relative plausibility).
