According to reports, a discovery in Kenya has revealed that Homo erectus and Paranthropus boisei, two different hominin species, co-existed 1.5 million years ago. The footprints were found in 2021 at Kubi Fora near Lake Turkana, according to a study published in the journal Science on Thursday. These findings show that these two species not only have similarities Environment But negotiations can also take place. The team, led by Chatham University paleontologist Kevin Hatala, analyzed a 26-foot-long trail of fossilized footprints.
Using advanced 3D imaging techniques, the researchers identified tracks from individuals with different foot shapes and walking patterns. According to the source, it was concluded that the high arches and heel-to-toe footprints were left by Homo erectus, whose body structure is very similar to that of modern humans. In contrast, flatter footprints, marked by deeper forefoot impressions, were attributed to Paranthropus boisei, known for its robust build and distinct big toe.
according to StudyFootprints provide detailed insight into the physical differences between species. A single trackway contained a dozen prints of a P. boisei individual, whose foot size was equivalent to that of modern American men, size 8.5.
Meanwhile, H. erectus footprints were smaller, corresponding to a shoe size of 4 for women and 6 for men. Jeremy DeSilva, a paleontologist at Dartmouth College. told Live Science says the discovery provides a rare glimpse into their movements and potential behavioral dynamics.
Implications for hominin interactions
Hatala told the publication that these species likely recognize each other differently, comparing it to interactions seen between chimpanzees and gorillas today. Paleoanthropologist Zach Throckmorton of Colorado State University reportedly highlighted that stability of the big toe, evident in H. erectus, is an important adaptation for walking and running.
The overlapping tracks, made within a few hours of each other, suggest that these species shared a landscape in more close proximity than previously thought. Although their exact interactions remain speculative, the discovery opens new avenues for understanding early human evolution.
