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

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,

Scientists discovered fossilized footprints along Lake Turkana, Kenya, revealing that early human ancestors Homo erectus and Paranthropus boisei coexisted around 1.5 million years ago. The distinct footprints show different walking styles,

(Reuters) - 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, horses, warthogs, giant storks and other animals.

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

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.**

A new discovery of fossils dating back 1.5 million years is giving scientists fresh insight into the behaviors of human ancestors known as hominins. An international team of researchers said Thursday that they had found two sets of hominin footprints that were made about the same time on an ancient lake’s shore in present-day Kenya.

More than a million years ago, on a hot savanna teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food.
