Article body:
When we talk about human evolution, not many of the people can differentiate between the different stages that happened. To some, they cannot even remember a single stage of human evolution they learned in school. However, this article discusses the different stages of human evolution. It will involve characteristics, and the time each group existed as discussed below.
1. Homo habilis or the hardy man
This man is said to have lived in the eastern and southern part of Africa. He lived between 2.4 to 1.4 million years ago. He had a brain capacity of approximately 600cc with an ape-like face. His arms were long, and he had an elongated skull. He was named the hardy man as he was the first man to make stone tools using primitive technology. He weighed approximately 70lbs and had an average height of 3ft. Their tooth dental formula was meant for chewing hard foods. Scientists claim that in most instances they fed on foods like leaves, woody plants as well as animal tissues. They were hunters and gathers with less farming practiced at this stage.
2. Homo erectus
Homo erectus is commonly referred to as upright man stage. They lived approximately 2 million to 100, 000 years ago. According to scientists, Homo erectus lived across the globe in countries such as Kenya, South Africa, China, and Spain. This man grew up to a height of 6 feet which is the standard height of a modern man. Their brain capacity is said to be approximately 1200cc, around 60% of the modern man brain. With the large brain capacity, they needed a diverged diet, including of more animal protein to survive. At this stage, the man was able to make sophisticated tools as a result of his hand strength and dexterity. Also, they were the first to use fire to cook their meals. Their farming was as well more developed as a result of better tools.
3. Neanderthals
Neanderthals initially were recognized as subspecies of Homo sapiens. This was not, however, the case as it was later discovered that they were different creatures. They existed around 30, 000 years ago and are said to have been well adapted to the cold climate. Their brain capacity was said to be around 1430 cc close to that of modern human beings. They had large bodies and more strength than the later Homo sapiens with stronger skeletons. However, they did not have the chin eminence, with their mandible larger and heavier. They used different languages for communication, with better iron tools like spears for hunting. It is also believed that they could play musical instruments on their own. They were also able to do better farming compared to their predecessors.
4. Homo Sapiens
This is the stage of the modern man. Oldest modern man skulls are believed to have lived 23, 000 years ago. It is said that he originated from Africa and spread to the rest of the world so quickly. He adapted to different climatic conditions and soon after the skin color changed. Compared to his ancestors, the modern man is less strong. Regarding technology, modern man has been able to make more sophisticated tools. He can do better farming, and he uses more developed technology for hunting and agriculture. He has an approximate brain capacity of 1500cc with an average height of 6 fits. He is also considered to be the only evolution species that live on earth to date. There is also a proper distinction between modern females and males concerning shape, height, and size.
In conclusion, the evolution of man is one of the most interesting topics to learn about. It offers knowledge about human development and how human came into existence. Reading the article, however, equips one with the basic knowledge about the above four stages.
