Final answer:
Homo Sapiens, including modern humans, evolved in Africa about 200,000 years ago. They expanded out of Africa approximately 100,000 years ago, replacing other human species.
Step-by-step explanation:
The Homo Sapiens species, which includes modern humans, evolved in Africa approximately 200,000 years ago. They were tall individuals with rounded skulls, steep foreheads, well-developed chins, and an average cranial capacity of about 1,400 cubic centimeters.
Around 100,000 years ago, Homo Sapiens expanded out of Africa and replaced all other human species, according to the commonly accepted 'out of Africa' model. This model suggests that Homo Sapiens emerged first in Africa and then migrated to other parts of the world. This is supported by the 'out of Africa' model, which suggests that Homo Sapiens originated in Africa and migrated to other regions.
