Definition of Human Evolution

Charles Darwin gave the concept of human evolution. Evolution refers to changes that occur due to natural processes in living beings. Concerning human evolution, Darwin stated that human reasoning and activities, particularly in the ethical domain, had a developmental beginning similar to physical nature. Darwin also stated the different stages of human evolution as a process starting from Dryopithecus and lasting with Homo Sapiens. Let us look at the stages of human evolution in detail.

What is the meaning of evolution?

The term evolution refers to the process where many changes related to development occur. This term mainly refers to the genetic changes in the human life cycle across time per population. In time, things change, and we have no control over them. These changes mainly occur due to the generations. 

Meaning of evolution:

• The word ”evolution” is derived from the Latin word evolution. Which means the opening or unrolling stage.
• Mainly, it includes simple or complex problems.
• In biology, evolution refers to the genetic changes that occur due to the natural processes of growth development.

Human Evolution

The term human evolution includes many changes from time to time. All such changes are different from each other with respect to stage, whether it is a complex or straightforward stage. All the evolution takes place from time to time, as with the needs. When it is time to look at the changes, they get changed from many things. 

Many people have introduced theories on the human evolution process. Charles Darwin is the father of human evolution and describes the concept with these terms. 

• Natural selection
• Struggle to exist
• Variation and survival of the fittest

Evolution is the primary outcome of many interactions between five main processes. The five processes are according to types, as mentioned below.

1. Genetic Recombination
2. Mutation
3. Chromosomal Abnormalities
4. Natural Selection
5. Reproductive isolation

Definition

In the Origin of Species, Charles Darwin notes little regarding human advancement other than to prove that people did advance and are essential for the interrelated normal world alongside any remaining living beings.”

• Anyway, this should not cover Darwin’s incredible interest in the theme, a difference to which he turned in his Descent of Man, where he made exceptionally clear the regular cycles unrolling homo sapiens.
• Darwin states that he thinks human reasoning and activities, particularly in the ethical domain, have a developmental beginning similar to our actual nature.

Stages of human evolution

The main stages related to human evolution are discussed below. These are the particular stages that are found in the different regions. All the stages are discussed below:

Stage 1. Dryopithecus

• Great apes are the progenitor of both man and chimps. They lived in Africa, China, Europe, and India. 
• Dryopithecus was alive, and tropical swamps occupied by it were thickly forested. Hence, it might not have been overwhelmingly herbivores.
• The family Dryopithecus alludes to oak wood gorillas. 

Stage 2. Ramapithecus – extinct apes

• Its remains were first found in Punjab’s Shivalik range and later in Saudi Arabia and Africa. 
• They lived in open prairies. 
• They use their hands for food and safeguard and extrapolations of upstanding stance.

Stage 3. Australopithecus

• Its fossil was found in South Africa in the year 1924.
• They used to live on the ground, used stone weapons, and walked in an erect manner. Their height was around 4 feet, and they weighed approximately 60-80 pounds.

Stage 4. Homo Erectus

• The Homo Erectus fossil was first spotted in Java in 1891. It was called Pithecanthropus Erectus. 

Stage 5. Homo Sapiens Neanderthalensis

• Evolution Homo Erectus made them Homo Sapiens. 
• During development, 2 subspecies of Homo Sapiens have been distinguished: Homo sapiens and Homo sapien Neanderthal. 
• The cranial limit of Neanderthal developed from 1200 to 1600 cc. 
• These types of primates could chase large names like mammoths.

Stage 6. Homo Sapiens

• The remaining parts of Homo Sapiens were found in Europe for the first time and were named Cro-Magnon. 
• Its jaws were smaller, the advanced man’s jawline showed up, and the skull adjusted. Their cranial limit was around 1350 cc.
•  They assembled food through hunting. Workmanship initially showed up during this period.

Conclusion

From here, we see that there are many different stages of human evolution. The term human evolution refers to the changes in the body. Generally, this is a concept given by Charles Darwin, who explains the different stages of human evolution. The stage starts from  Dryopithecus and will go along with 5 other stages. All the different parts of stages will be found in specific areas along with different things.
