What is the Difference Between Homoerectus and Homosapien?

Homo erectus and Homo sapiens are two distinct species within the human lineage, with several key differences between them:

1. Brain Size and Intelligence: Homo erectus had a smaller brain (850cc to 1100cc) and was less intelligent than Homo sapiens, which has a larger brain (1300cc) and is more intelligent.
2. Speech: Homo sapiens were capable of modern speech, while Homo erectus had primitive speech.
3. Jaws and Teeth: Homo erectus had heavily built jaws and larger teeth, while Homo sapiens had less heavily built jaws and smaller teeth.
4. Facial Features: Homo erectus had more prognathism and heavy brow ridges, while Homo sapiens had fewer brow bridges and less prognathism.
5. Height: Homo sapiens were generally taller than Homo erectus.
6. Arms and Legs: Homo erectus had slender arms and longer legs, while Homo sapiens had less slender arms and shorter legs.
7. Lifestyle: Both species had an ancestral relationship and originated from the African continent. They both had a complex lifestyle, an extended childhood, and hunted. Both species were capable of making tools and using fire.

Homo erectus is considered an ancestor of modern humans, and it was the first known hominin to migrate out of Africa and possibly the first to cook food. In contrast, Homo sapiens is the species to which all modern human beings belong.

Comparative Table: Homoerectus vs Homosapien

Here is a table comparing the differences between Homo erectus and Homo sapiens:

Homo erectus is an extinct species of the human lineage, with an upright stature and well-evolved postcranial skeleton, but with a smaller brain, low forehead, and protruding face. On the other hand, Homo sapiens is the species to which all modern human beings belong, characterized by a larger brain, more intelligence, and modern speech.
