Final Answer:
African Replacement (Out of Africa theory) refers to Homo Sapiens replace existing lineages by migrating out of Africa and supplanting other species, leading to their extinction.
Step-by-step explanation:
The "Out of Africa" theory elucidates Homo sapiens' migration from Africa around 200,000 years ago. Predecessors, like Homo erectus and Neanderthals, had already populated regions outside Africa. However, as Homo sapiens spread, they outcompeted and interbred with these species. This interaction eventually led to the extinction of other lineages due to various factors.
The Homo sapiens' advancements in technology, social organization, and adaptation to diverse environments played a crucial role in their dominance. They might have had more sophisticated tools, better communication, or superior strategies for survival. These advantages likely contributed to their ability to replace existing species.
This replacement wasn't solely about aggression; it involved a complex interplay of factors, including environmental changes, competition for resources, and potential interbreeding. Over time, these factors led to the decline and eventual extinction of other hominin species, leaving Homo sapiens as the sole surviving lineage.
