Footprints Reshape What Scientists Know About Extinct Human Relative
Advanced imaging and bone comparisons found traits linked to bipedalism in Sahelanthropus tchadensis, strengthening the case for an early human ancestor.
- A new study in Science Advances presents evidence that Sahelanthropus tchadensis, a seven-million-year-old fossil species, was capable of upright walking, suggesting bipedalism evolved early in the human lineage.
- For decades, researchers argued over whether the ancient fossil could walk on two legs, as early research focused on the skull, which provided limited insight into how the species actually moved.
- NYU anthropologist Scott Williams identified a femoral tubercle in Sahelanthropus that anchors the iliofemoral ligament, critical for upright walking; researchers also found a relatively long femur supporting bipedal behavior.
- Separately, researchers found 21 footprints at Lake Turkana in Kenya dating to 1.4 million years ago, revealing that Paranthropus individuals were taller than previously thought and traveled in groups.
- According to study lead Kevin Hatala, these findings provide a "snapshot" of early hominin life, reshaping scientists' understanding of human evolution and our ancient relatives' movement and behavior.

Ancient footprints offer rare glimpse into lives of extinct human relatives
A remarkable set of footprints preserved along the shores of Kenya’s Lake Turkana from more than one million years ago is giving scientists an unusually detailed look at how one of humanity’s extinct relatives may have lived, moved and socialized.
This ancient fossil could rewrite the story of human origins
Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ligament attachment seen only in human ancestors. Despite its ape-like appearance and small brain, its leg and hip structure suggest it moved confidently on two legs. The finding places bipedalism near the very root of the human family tree.
