A study by an international team reveals 1.5-million-year-old footprints from Koobi Fora, Kenya, showing two distinct patterns of Pleistocene hominin bipedalism on the same surface. This discovery suggests that ancient hominin species coexisted as neighbors. Scientists stated that, over a million years ago, two different species might have crossed paths on a hot savannah near Lake Turkana.
