Fossil footprints reveal body size and group dynamics of 1.4-million-year-old human relative
New analysis of 1.4-million-year-old fossil footprints suggests early human relatives were larger and lived in different social structures than previously assumed.
The brief
These insights shift the current understanding of how early human relatives interacted and evolved within their environments nearly 1.5 million years ago. The findings, detailed by outlets including Phys.org, Smithsonian Magazine, and New Scientist, identify fossilized tracks located at an ancient lakebed in Kenya.
The data indicates that these individuals possessed larger body sizes than previous fossil records suggested. Popular Science notes that the spatial distribution of these prints may imply the group traveled in all-male packs.
While the discovery provides a snapshot of locomotive and social behavior, coverage does not yet specify the exact evolutionary relationship between this mystery hominin and modern humans. Future studies will determine if these specific findings are indicative of the wider species' lifestyle or represent an isolated incident at this African site.
