The study indicates that Earth's environment during the Carboniferous period, characterized by the supercontinent Pangea, was significantly different than today.
While high atmospheric oxygen levels were present, the correlation with insect size is now under scrutiny, suggesting other environmental factors may have played a role.
This challenges existing models of insect evolution and highlights the need for a more nuanced understanding of ancient ecosystems and their influence on biological development.
