Ancient Footprints Reveal 2 Human Ancestors Walked the Same Path in Kenya at the Same Time

In a groundbreaking discovery, researchers have uncovered evidence that two distinct species of ancient human relatives, *Homo erectus* and *Paranthropus boisei*, walked the same ground at the same time approximately 1.5 million years ago. The footprints, preserved in dried mud near a lake in northern Kenya, were left within hours or days of one another, raising intriguing questions about the interactions and relationships between these species.  

 

 

The discovery, detailed in a study published in *Science*, offers the first direct evidence that these species coexisted in the same location. By analyzing the footprints’ shapes and strike patterns, researchers concluded that the tracks were made by two different species. “We think that these individuals, these two species that were there, probably would have been aware there were members of another species nearby,” said Kevin Hatala, associate professor of biology at Chatham University and lead author of the study. “They would have seen each other and recognized each other as different species, which raises questions about what those interactions would have been like. Were they competitors? Were they totally OK with each other being there?”  

 

The study adds to the growing understanding among anthropologists that ancient human relatives not only coexisted but also likely interacted. Previously, fossil remains of both species were found in the region, showing that they lived there during overlapping time periods. However, these footprints provide direct evidence of their simultaneous presence.  

 

While both species were bipedal, their walking styles differed significantly. *Homo erectus* exhibited humanlike anatomy from the neck down, used stone tools, and possibly cooked with fire. This species had a varied diet that likely included meat and managed to spread across Asia, Indonesia, and other regions. Its resilience allowed it to survive for over a million years after these footprints were made, disappearing from the fossil record a little over 100,000 years ago. Hatala described *Homo erectus* as “a very successful species” and a potential direct ancestor of modern humans.

In contrast, *Paranthropus boisei* was characterized by a smaller brain, massive chewing muscles, and large molars. This species is thought to have specialized in eating tough foods such as hard nuts and fibrous plants. Its evolutionary journey ended much sooner than that of *Homo erectus*, representing an evolutionary dead end. “Human evolution is complicated and messy, and there’s lots of experimentation. It’s not a straight line,” said William Harcourt-Smith, associate professor of anthropology at Lehman College, who was not involved in the study.

The conditions under which the footprints were preserved also provide valuable insights. The tracks, untouched by other animals and uncracked before being buried in sediment, suggest they were left in quick succession. “The sediment protected them and prevented them from cracking and allowed them to be entered into the geologic record,” Hatala explained.

 

One possible reason the two species coexisted peacefully in the area could be their differing diets, which may have reduced competition for resources. However, researchers also speculate that they might have had antagonistic relationships or competed for other resources. The discovery highlights that ancient human species interacted and coexisted across different habitats over millions of years.  

 

These findings illuminate the complex and intertwined pathways of human evolution. While species like *Paranthropus boisei* represent evolutionary dead ends, others like *Homo erectus* laid the groundwork for modern humans. The discovery of these footprints serves as a poignant reminder of the diverse and interconnected nature of our ancestral history.

The earliest short-term pickup?

Surely no different to today's human walking through a jungle, and  monkey walking on the same path hours later?

a) Monkey not a Hominid.

 

b) Monkey not bipedal except occasionally, as are none of todays Great Apes (which are hominids) except occasionally.

 

Having those two walk the same path is like you and a Neanderthal walking down Beach Road one after the other.

...which happens pretty frequently, especially in the wee hours. Or at least it feels like it 😄
