A new, “mind-blowing” discovery reveals evidence that Homo erectus and Paranthropus boisei stepped at the same site within days—or hours—of each other

The "huge" discovery near the shore of Lake Turkana in Kenya proves the theory that some ancient ancestors were neighbors

There’s plenty of evidence that ancient hominin species crossed paths on many occasions – but it’s never been quite as literal as a new discovery in Kenya. Paleontologists have discovered the first known example of fossil footprints left by two different species of ancient hominins on the same day.

Scientists discovered 1.5-million-year-old footprints in Kenya, revealing two hominin species coexisted and interacted.

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