Difference Between Homoerectus and Homosapien

Key Difference – Homoerectusvs Homosapien

The numbers ofHomotypes are categorized broadly under the archaic human group which was originated in the period beginning 500,000 years ago. Typically, this group consists ofHomo neanderthalensis(250,000 years ago),Homo rhodesiensis(300,000 years ago),Homo heidelbergensis(600,000 years ago)andHomo antecessor(1200, 000 years ago).This archaic human group is completely contrasting to the modern humans based on anatomic traits. TheHomo sapiens sapiensandHomo sapiens idaltuare categorized under modern humans. According to “Toba catastrophe theory” the modern humans were originated after 70000 years ago. Recent genetic studies have suggested that the modern humans were evolved from at least two ancient human varieties such asNeanderthalsandDenisovans. Theoretically, the modern humans have evolved from archaic humans who in turn evolved fromHomo erectus. Thekey differencebetweenHomo ErectusandHomo sapienis,Homo erectushad a smaller brain and was less intelligent, whereasHomo sapienhad a larger brain and was more intelligent.

Who isHomo Erectus?

TheHomo Erectusis also called “upright man”. They are distinguished from modern humans and archaic humans groups. It was widely believed that the population similar toHomo erectuswas ancestors to modern living human beings “Homo sapiens”. TheHomo Erectusthought to have evolved in Africa 1.8 million years ago. They first migrated to Asia and then to Europe. It is suggested, this species became extinct 0.5 million years ago. This timing factor placesHomoerectusbetweenHomo habilisand modern appearance ofHomo sapiens. The migration ofHomo Erectus亚洲和欧洲似乎100万年s ago.

Recently the lower jaw of an individual ofHomo erectuswas found from Georgia. And it was dated back to 1.6 million years ago. They were the first appearance ofhominidsoutside Africa. Also,Homoerectuswas the first to incorporate systemic hunting in their lifestyle. They were the first to have an extended childhood.Homoerectushad tool making capability and capability of using fire. And also they were capable of more complex lifestyles. Their brain size and body size was bigger compared toHomo habilis. The brain size was 850-1100 cc. The body size of a male was 1.8 meters and 1.55 meters in females.

TheHomo Erectusused stone tools such as hand axe. They had long and lowcranium.Homoerectusalso had a short and wide face with projected nasal aperture forward. The pronounced brow ridges were also prominent in this group. The most striking behavioral feature of this group is the reduction of body size dimorphism between sexes.

Who isHomo Sapiens?

Due to a dramaticclimate change,Homo sapienshave evolved 200,000 years ago in Africa. Their behaviors have evolved over the years and made them successfully face the challenges in the unstable environment. Compared to the earlier humans, the modern humans possessed a lighter build skeleton. The modern humans have a short femoral neck attached to a larger head. Their brain size is much larger and it is around 1200 cc. The subspeciesHomo sapiens sapiensandHomo sapiens idaltuare included in this group. TheHomo sapiens idaltuis the subspecies ofHomo sapiensthat are found in 1997 Herto Bouri in Ethiopia.

Homo sapiensare the first to depict the modern speech. A thin walled high vaulted skull with a flat and near vertical forehead is a striking feature of the modern man. And the modern human faces also show less heavy brow ridges and prognathism. And also, their jaws are less heavily developed with smaller teeth. According to the evolutionary relationship, it is still unknown the direct ancestor ofHomo sapiens.Many paleoanthropologists think that it can beHomoheidelbergensisor some other.

What are the Similarities Between Homoerectus and Homosapien?

• Both have the ancestral relationship.
• Both have originated from the African continent.
• Both have used to the complex lifestyle.
• Both have had an extended childhood and both have hunted.
• 都有制造工具的能力and using fire.

What is the Difference Between Homoerectus and Homosapien?

Homoerectus vs Homosapien
Homoerectus is an extinct species of the human lineage, having upright stature and a well-evolved postcranial skeleton, but with a smaller brain, low forehead and protruding face.	Homo sapienis the species to which all modern human beings belong.
Intelligence
Homoerectushad a smaller brain and was less intelligent.	Homo sapienhad a larger brain and was more intelligent.
Brain Size
Homoerectushad 850cc to 1100cc brain.	Homosapienhad 1300cc brain.
Modern Speech
Homoerectusdid not show modern speech.	Homosapienshad modern speech.
Teeth
Homoerectushad larger teeth.	Homo sapienshad smaller teeth.
Jaws
Homoerectushad heavily build jaws.	Homo sapienshad less heavily build jaws.
Brow Ridges and Prognathism
Homoerectushad heavy brow bridges and more prognathism.	Homo sapienshad fewer brow bridges and less prognathism.

Summary – Homoerectusvs Homosapien

Homo neanderthalensis,Homo rhodesiensis,Homo heidelbergensisandHomo antecessorare the archaic humans.This archaic human group is completely contrasted to the modern humans based on anatomic traits. TheHomo sapiens sapiens and Homo sapiens idaltuare categorized under modern humans.Homo sapiens idaltuwas first discovered in Herto Bouri, in Ethiopia. According to “Toba catastrophe theory”, the evolutionary process of modern humans was after 70000 years ago. The evolution of modern humans most probably was started 200,000 years ago. Recent genetic studies have suggested the modern humans were evolved from at least two ancient human species such asNeanderthalsandDenisovans. Theoretically, the modern humans have evolved from archaic humans who in turn evolved fromHomo erectus. This is the difference between Homoerectus and Homosapien.
