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

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

(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.

Smithsonian: Fossil Footprints Reveal That Two Early Human Relatives Lived on the Same Landscape in Kenya 1.5 Million Years Ago

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

A set of footprints found at the site of Koobi Fora in Kenya reveals that our ancestor Homo erectus coexisted with a now-extinct bipedal hominin, Paranthropus boisei, 1.5 million years ago.

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.

Two sets of fossilized footprints from early human species were made within a few hours of each other about 1.5 million years ago, researchers suggest

Intersecting paths of muddy footprints left on a Kenyan lakeside 1.5 million years ago suggest two of our early human ancestors were nearby neighbours.
