A new study reports that early humans experienced a marked increase in size around two million years ago. Researchers describe this period as a “growth spurt,” during which human growth accelerates compared with earlier patterns. The findings are based on analyses of changes in growth-related biological traits over time, linking the timing of faster growth to evolutionary changes in early Homo populations.
The outlets agree on the central claim: that humans “jumped” in size roughly two million years ago. They also report a proposed functional implication—faster growth may have made it easier for early humans to travel longer distances, consistent with changing demands of movement and survival during that era.
While the reports emphasize the potential significance for mobility, they do not provide detailed methodology or additional competing interpretations in the excerpts provided. Overall, the coverage presents the study’s timing and the suggested advantage of increased growth rate as the main conclusions.
