The brief
New findings indicate that human ancestors experienced a sudden, substantial increase in body size approximately 2 million years ago. This discovery directly challenges long-standing models suggesting that physical growth occurred steadily over the course of human evolution.
Coverage from Phys.org, IFLScience, Discover Magazine, Neuroscience News, and Sci.News emphasizes the departure from traditional evolutionary timelines. Reports highlight that the transition was characterized by a distinct leap rather than a continuous trend.
Future reports may clarify the specific biological or environmental factors associated with this period of change. Coverage does not yet specify the exact mechanism behind the sudden growth spurt observed in the data.
