No evidence that warmer temperatures are associated with selection for smaller body sizes

Siepielski, Adam M.; Morrissey, Michael B.; Carlson, Stephanie M.; Francis, Clinton D.; Kingsolver, Joel; Whitney, Kenneth D.; Kruuk, Loeske


Reductions in animal body size over recent decades are often interpreted as an adaptive evolutionary response to climate warming. However, for reductions in size to reflect adaptive evolution, directional selection on body size within populations must have become negative, or where already negative, to have become more so, as temperatures increased. To test this hypothesis, we performed traditional and phylogenetic meta-analyses of the association between annual estimates of directional...[Show more]
