Why did only one hominid species, us, survive out of the many that developed?

One possible reason why only one hominid species, Homo sapiens, survived out of the many that developed is due to a combination of factors such as environmental changes, competition with other species, and adaptability. Homo sapiens may have had unique characteristics that allowed them to outcompete other hominid species and adapt to changing environments more effectively. Additionally, factors such as social organization, communication skills, and technological advancements may have also played a role in the survival and dominance of Homo sapiens.
