Final answer:
Homo sapiens sapiens most likely emerged from Homo erectus, who migrated out of Africa about 100,000 years ago.
Step-by-step explanation:
H. sapiens sapiens, also known as anatomically modern humans, most likely emerged from H. erectus. H. erectus first appeared approximately 1.8 million years ago and eventually migrated out of Africa. It is believed that modern humans arose in Africa from H. erectus and migrated out of Africa about 100,000 years ago, replacing H. erectus species that had migrated into Asia and Europe in the first major migration wave.
