This theory is supported by a large body of evidence, including:
* Fossil records: The oldest known Homo sapiens fossils, dating back to around 300,000 years ago, have been found in East Africa.
* Genetic evidence: DNA analysis shows that all living humans share a common ancestor who lived in Africa about 200,000 years ago.
* Archaeological evidence: Early tools and artifacts associated with Homo sapiens have also been found in East Africa.
However, it's important to note that the details of the early human evolution process are still being studied and debated by scientists.
