Question

what is one possible reason that all other hominid species went extinct?

Explanation:

One possible reason is competition with Homo sapiens (modern humans). As Homo sapiens developed advanced tools, language, and social structures, they outcompeted other hominids for resources like food, shelter, and territory. Additionally, Homo sapiens may have caused direct conflicts or transmitted diseases to other hominid species, contributing to their extinction. Environmental changes (e.g., climate shifts) could also have affected other hominids' ability to adapt, while Homo sapiens' adaptability (via culture, technology) helped them survive.

Answer:

Competition with Homo sapiens (modern humans) for resources (food, territory, etc.), along with potential direct conflicts, disease transmission, or inability to adapt to environmental changes as effectively as Homo sapiens.
