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.

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

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.

WASHINGTON — Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago. The footprints were left in the mud by two different species “within a matter of hours,

In a new discovery near Kenya’s Lake Turkana, scientists have uncovered fossilized footprints from two distinct hominin species dating back 1.5 million years. This marks the first known instance of two hominin species leaving tracks on the same surface,
