The Summary Ancient footprints discovered in Kenya belong to two different species of human relatives who walked on the same ground at the same time, a study found. The prints are thought to belong to the species Homo erectus and Paranthropus boisei. A newly discovered set of footprints in Kenya provides the first evidence that two different species of ancient human relatives walked the same ground simultaneously 1.5 million years ago. While both are human relatives, Homo erectus and Paranthropus boisei featured very different traits, and their fates within the human evolutionary tree took starkly different routes. Broadly speaking, Harcourt-Smith added, it has become increasingly clear that various ancient human species interacted across different habitats over the past 7 million years of evolution.
