Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were neighbors some 1.5 million years ago.

Muddy footprints found beside Lake Turkana, Kenya reveal two ancient hominin species were once neighbors 1.5 million years ago.

Study provides first evidence of different bipedalism styles on same footprint surface, attributed to both species.

About 1.5 million years ago, individuals of two different species in the human evolutionary lineage trudged on a muddy lakeshore in northern Kenya, leaving behind intersecting trackways alongside the footprints of antelopes,

A discovery in northern Kenya hints that two extinct species that were our ancient relatives shared the same habitat and possibly interacted.

Researchers discovered 1.5-million-year-old footprints in Kenya's Turkana Basin, revealing coexistence of Paranthropus boisei and Homo erectus. The prints, showing distinct walking patterns, provide direct evidence of the two species' interaction and environment,

Found at Koobi Fora near Lake Turkana, the footprints show that *Paranthropus boisei* and *Homo erectus* shared the same habitat, offering new insights into their coexistence and evolutionary paths.**

Two species of ancient human relatives crossed paths 1.5 million years ago. Fossilized footprints in Kenya captured the moment, according to a new study.

Human footprints stir the imagination. They invite you to follow, to guess what someone was doing and where they were going. Fossilized footprints preserved in rock do the same—they record instances in the lives of many different extinct organisms,

Newly discovered 1.5-million-year-old footprints reveal how two extinct human species crossed paths within hours of each other.
