1. The mechanisms that underpin the evolution of ageing and life histories remain elusive. Oxidative stress, which results in accumulated cellular damages, is one of the mechanisms suggested to play a role. 2. In this paper we set out to test the ‘oxidative stress theory of ageing’ and the ‘oxidative stress hypothesis of life histories’ using a comprehensive phylogenetic comparison based on an unprecedented dataset of oxidative physiology in 88 free-living bird species. 3. We...

Data from: The influence of multiple functional demands on morphological diversification: A test on turtle shells

Charles Tristan Stayton, Lauren F. O'Conner, Nicole Marie Nisivoccia & Lauren F. O'Connor
Organismal parts are often involved in the performance of more than one function. The role of trade-offs in influencing phenotypic evolution of such parts is well-studied; less well-understood is their role in influencing phenotypic diversity. Increases in the number of functions a part is involved in may inhibit subsequent diversification, as the number of trade-offs increases. Alternately, such an increase might promote phenotypic diversification, by increasing adaptive landscape complexity and promoting specialization for different roles....
