The brief
A new study disputes the long-held belief that human ancestors increased in size along a steady, linear trajectory. Instead, findings indicate that human ancestors got substantially bigger around 2 million years ago.
Coverage from Phys.org, IFLScience, and Sci.News emphasizes that this discovery challenges previous ideas regarding the timing and nature of human growth. Discover Magazine and Neuroscience News further highlight the suddenness of this size increase.
Future analysis may focus on why this specific leap in body size occurred 2 million years ago, as indicated by the reporting from Neuroscience News.
