Solution

1. Homo erectus

The Homo Erectus is also called “upright man”. They are distinguished from modern humans and archaic humans groups. It was widely believed that the population similar to Homo erectus was ancestors to modern living human beings “Homo sapiens”. The Homo Erectus thought 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 places Homoerectus between Homo habilis and modern appearance of Homo sapiens. The migration of Homo Erectus to Asia and Europe appeared to have 1 million years ago.

2. Homo sapiens

Due to a dramatic climate change, the Homo sapiens have 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 subspecies Homo sapiens sapiens and Homo sapiens idaltu are included in this group. The Homo sapiens idaltu is the subspecies of Homo sapiens that are found in 1997 Herto Bouri in Ethiopia.

Difference Between Homoerectus and Homosapien
Features Homo Erectus Homo sapiens

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 sapien is the species to which all modern human beings belong.

Intelligence Homoerectus had a smaller brain and was less intelligent. Homo sapien had a larger brain and was more intelligent.

Brain size Homoerectus had 850cc to 1100cc brain. Homosapien had 1300cc brain.

Modern speech Homoerectus did not show modern speech. Homosapiens had modern speech.

Teeth Homoerectus had larger teeth. Homo sapiens had smaller teeth.

Jaws Homoerectus had heavily build jaws. Homo sapiens had less heavily build jaws.

Brow Ridges and Prognathism

Homoerectus had heavy brow bridges and more prognathism. Homo sapiens had fewer brow bridges and less prognathism.
