Why climate change should generally lead to lighter coloured animals

How species will adapt to future climate change is a key question in modern biology. One way to predict such adaptation is to draw from our knowledge of current spatial patterns of phenotypic variation. These are often summarised by different ecogeographical rules that describe how environmental gradients predict geographic variation in form and function. A recent review in Current Biology [1Tian L. Benton M.J. Predicting biotic responses to...
