Why did the fosil Boule examined walk hunched over?

The fossil examined by Boule likely walked hunched over due to its anatomical structure, which was adapted for a different mode of locomotion than modern humans. This posture may have been a result of adaptations for climbing or navigating through varied terrains, reflecting its evolutionary history. Additionally, its skeletal features, such as a more curved spine and shorter legs, could have contributed to this hunched posture, indicating that it was not fully bipedal like contemporary human beings.
