Recent studies indicate that the evolution of human body size may not have followed a gradual trajectory as previously thought. Instead, researchers found notable increases at specific points in time.
The most significant change in body size is believed to have occurred between 2 and 2.5 million years ago, coinciding with the emergence of species such as Homo rudolfensis or Homo erectus/ergaster.
These findings challenge the conventional view of a continuous increase in size throughout human evolution, suggesting a more complex pattern of development.
