What did the interaction between H. sapiens and Neandertals suggest?

The correct answer highlights the interaction between Homo sapiens and Neandertals, suggesting that they likely shared habitats and resources. Archaeological and genetic evidence indicates that these two species coexisted for a significant period in certain regions, particularly in Europe and parts of Asia. This coexistence implies that they were able to occupy similar environments and possibly compete for similar resources, such as food and shelter.

Additionally, studies have shown that there was interbreeding between the two species, leading to some Neandertal DNA being present in modern non-African human populations. This further supports the idea that they interacted in various ways and were not isolated from one another. In essence, the evidence points towards a complex relationship that involved both competition and coexistence in their shared habitats.
