Ancient Footprints Reveal Coexistence of Human Ancestors in Kenya

Scientists have discovered 1.5-million-year-old footprints in Kenya, revealing that two different species of human ancestors, Homo erectus and Paranthropus boisei, walked the same path within hours of each other. This finding, published in Science, provides the first evidence of these species coexisting in the same habitat, offering new insights into human evolution and interactions. The study utilized advanced 3D imaging to analyze the footprints, highlighting the significance of trace fossils in understanding ancient human behavior.
