Why
To investigate the evolutionary drivers of tuna size, speed, and thermoregulation, challenging the hypothesis that the K-Pg extinction event created an ecological opportunity for their rapid evolution.
The Frontline Impact
How this affects you
The study challenges a prevailing theory on tuna evolution, suggesting that factors other than the K-Pg extinction event were primarily responsible for the development of these economically important fish.
