The archaic human group, which came into being about 500,000 years ago, is a broad category for the different kinds of Homo.
Homo neanderthalensis (250,000 years ago), Homo rhodesiensis (300,000 years ago), Homo heidelbergensis (600,000 years ago), and Homo antecessor (1200, 000 years ago) are usually included in this group.Based on how they were built, this ancient human type is very different from modern humans.
Homo sapiens sapiens and Homo sapiens idaltu are considered modern humans. The “Toba disaster theory” says that people changed more than 70,000 years ago.
Recent genomic research suggests that modern humans are related to at least two ancient human species, like the Neanderthals and the Denisovans. In theory, modern humans evolved from Homo erectus and then from Homo sapiens.
The main difference between Homo erectus and Homo sapien is that Homo erectus had a smaller brain and was less smart, while Homo sapien had a bigger brain and was smarter.
Who is Homo Erectus?
The “upright man” is another name for Homo erectus. They are different from both modern and ancient people. People used to think that Homo sapiens, or modern humans, were related to a group of people who were similar to Homo erectus.
It is thought that Homo erectus came from Africa 1.8 million years ago. They went to Asia first, and then they went to Europe. It is thought that this species died out about 0.5 million years ago.
This timeline puts Homo erectus between Homo habilis and the time when Homo sapiens came into being. It seems that Homo erectus moved to Asia and Europe 1 million years ago.
In Georgia, the lower jaw of a Homo erectus person was found not too long ago. It was discovered 1.6 million years ago. They were the first people to be found who lived outside of Africa. Homo erectus was also the first species to hunt in a planned way.
They were the first people to grow up for a longer time. Homo erectus knew how to make tools and how to use fire. They could also live in ways that were more complicated.
Both their bodies and brains were bigger than those of Homo habilis. The brain’s size was between 850 and 1100 cc. The length of a man’s body was 1.8 meters, while a woman’s was 1.55 meters.
Homo erectus used stone tools, such as a hand axe, to get things done. Their heads were long and low. Homoerectus also had a small, broad face with a nose that stuck out in front. In this group, the large brow ridges also stood out.
The most noticeable thing about this group’s behaviour is that there is no longer a difference in body size between males and females.
Who is Homo Sapiens?
Homo sapiens is the name of the primate species to which humans belong. About 200,000 years ago, they first showed up in Africa.
They have now spread all over the world. The two types of Homo sapiens are Homo sapiens sapiens and Homo sapiens idaltu. Homo sapiens idaltu is a living subspecies that is thought to be the ancestor of all modern humans.
People call him the name of the primate species to which humans belong. About 200,000 years ago, they first showed up in Africa. They have now spread all over the world.
The two types of Homo sapiens are Homo sapiens sapiens and Homo sapiens idaltu. Homo sapiens idaltu is a living subspecies that is thought to be the ancestor of all modern humans.
People call him “Hero man.” He first showed up in Pleistocene Africa about 160,000 years ago. Homo sapiens sapiens, on the other hand, is the name for modern people.
The modern human skull is bigger because it is less thick and the forehead is flat and almost vertical. Because of this, the brain size of Homo sapiens has grown.
The structure of the Homo sapiens skeleton is also lighter. Their teeth are smaller, and their jaws aren’t as strong.
Also, people today have access to more advanced tools like sewing needles and spear throwers. They have a steady life and know what it means to be tamed.
Modern people are able to think about things in an abstract way, plan in detail, have many different cultures, and use art and music as symbols.
Similarities Between Homo Erectus and Homo Sapiens
- There are two species in the human family tree: Homo erectus and Homo sapiens.
- Because they stand straight, they walk on two legs.
- They have a well-developed skeleton after the head and limbs that are similar to humans.
- Their teeth don’t look like ape teeth, but more like human teeth.
- Both of them are smart.
- Some of the things that make them stand out are that they used fire, looked for shelter in caves, and used different kinds of Acheulean stone tools.
- Both live in packs and hunt in packs.
Key Differences Between Homo Sapiens and Homo Erectus
|Basis||Homo Sapiens||Homo Erectus|
|Dispersal||Homo Sapiens were widely distributed.||Homo Erectus lived in Asia, Europe, and Africa by 1.8 Mya, throughout the world|
|Subspecies||Homo Sapiens idaltu (extinct) and Homo Sapiens sapiens are the two subspecies of Homo Sapiens||Nanjing Man, Lantian Man, Meganthropus, Peking Man, travel Man, and Solo Man are some subspecies of Homo Erectus|
|Brain Size||The size of the brain of Homo Sapiens was around 1300 cc||The size of Homo Erectus’s brain was 850 cc to 1100 cc|
|Intelligence||Homo Sapiens were more intelligent||Homo Erectus were less intelligent|
|Teeth||Homo Sapiens had smaller teeth||Homo Erectus had larger teeth|
|Jaws||Homo Sapiens had weaker jaws||The jaws of Homo Erectus were heavily built|
|Brow Ridges and Prognathism||Homo Sapiens had quite lite eye ridges and less prognathism||The eye ridges of Homo Erectus are very heavy and have more prognathism|
|Chin||Homo Sapiens had a more prominent chin||Homo Erectus had a less prominent chin|
|Facial Features||Homo Sapiens had faced similar to modern man||Homo Erectus had faced similar to apes|
|Skeleton||Homo Sapiens had weaker and thiner bones||Homo Erectus had stronger and thicker bones|
|Legs and Arms||The legs and arms of Homo Sapiens were shorter legs and less slender arms||The legs and arms of Homo Erectus were longer legs and more slender arms|
|Height||The height of Homo Sapiens was more||The height of Homo Erectus was less|
|Speech||The Homo Sapiens used modern speech||The Homo Erectus used primitive speech|
|Sexual Dimorphism||Sexual dimorphism is more pronounced in Homo Sapiens||Sexual dimorphism is less pronounced in Homo Erectus|
Homo erectus was the first person to stand up straight and the first person to use fire. He lived in caves and used tools made by humans. Homo sapiens, which is the ancestor of modern humans, is smarter than Homo erectus and uses better tools.
The main difference between them is that humans have a lighter body, a bigger brain, and tools. Here are the ways in which Homo erectus and Homo sapiens are different and the same.
