I don't think they found absolute brain mass was correlated with yawn duration. They scaled brain mass in some complicated way that might put rats above humans for all I know:
"we calculated residual brain mass measures from a phylogenetically controlled linear regression of the respective brain measure on body mass"
- true_religion 5y agoThere is a chart: https://www.nature.com/articles/s42003-021-02019-y/figures/2 https://www.nature.com/articles/s42003-021-02019-y/figures/2 Humans are above rats in this chart in both yawn duration and brain mass. Rats are above dogs though.
