Summary

Sahelanthropus tchadensis fossils suggest upright walking ability.
A unique femoral tubercle indicates adaptation for bipedalism.
More fossil evidence is critically needed to confirm its lineage.

Recent scientific analysis of Sahelanthropus tchadensis fossils, discovered in Chad's Djurab desert, indicates this ape-like species, living 7 million years ago, might be the earliest contender for the human lineage.

Researchers meticulously re-examined thigh and forearm bones, identifying a unique femoral tubercle and other features strongly suggesting adaptations for terrestrial bipedalism, a significant departure from typical knuckle-walking apes. This finding reignites a long-standing debate about the species' place in our evolutionary history.

However, the scientific community remains divided, with some experts calling the evidence for upright walking "weak" and urging caution. They stress that more extensive fossil evidence is essential to conclusively determine if Sahelanthropus tchadensis was indeed a precursor to modern humans.
