What can be inferred from the features of Nariokotome "Turkana Boy"?

Nariokotome "Turkana Boy," who lived around 1.6 million years ago, possesses several features that suggest he was well adapted to a terrestrial lifestyle. His long limb proportions, similar to those of modern humans, indicate a capacity for efficient bipedal locomotion, which is crucial for a ground-dwelling existence. Additionally, the skeletal structure suggests he was capable of enduring long distances, which would be beneficial for foraging, hunting, or migrating.

His cranial features, including a brain size that approaches modern human capacity, also imply capabilities for complex behaviors and possibly social organization that would align with a lifestyle on the ground rather than in trees. Overall, the morphological assessments of Turkana Boy paint a picture of a hominin suited for life on land, participating actively in the environmental dynamics of his time, such as hunting and gathering.

The other options suggest behaviors or lifestyles inconsistent with the available evidence. Living primarily in trees would not align with his physical traits, which are more akin to those of terrestrial mammals. Proposing that he was mainly a scavenger is too limiting given the evidence of his adaptability and potential skills in hunting. Additionally, stating that he had a strictly fruit-based diet overlooks the omnivorous tendencies of early
