Final answer:
Modern Homo sapiens evolved in Africa approximately 200,000 years ago, according to the most recent evidence. The 'out of Africa' theory suggests they expanded out of Africa around 100,000 years ago, while the 'multiregional evolution model' proposes Homo sapiens evolved from Homo erectus in several places around the same time.
Step-by-step explanation:
According to the most recent evidence, modern H. sapiens evolved in Africa approximately 200,000 years ago. The 'out of Africa' theory suggests that modern humans emerged in Africa around this time and then expanded out of Africa approximately 100,000 years ago. The second model, the 'multiregional evolution model,' proposes that Homo sapiens evolved from Homo erectus in several places around the same time.
