Two recent studies have shed light on the behavior and movement of ancient human relatives, based on discoveries in Spain and Kenya. In Spain, researchers excavating Gran Dolina cave have uncovered bones from 850,000 years ago that show signs of cannibalism. Both adults and children were butchered for meat, but the motive remains unclear—whether for food, ritual, or competition. The findings add to evidence that some early hominins practiced cannibalism. Meanwhile, in Kenya, a set of fossil footprints preserved along Lake Turkana's shores, dating back 1.4 million years, has provided insights into the body size and group dynamics of an extinct human relative. The trackways, described in a paper in the Proceedings of the National Academy of Sciences, show a group moving together, offering clues about their social structure and physical characteristics. These two studies, though from different locations and eras, both deepen our understanding of how ancient human relatives lived and interacted with their environments. Further research is expected to reveal more details about these early species.
