Data from: Kin recognition: evidence that humans can perceive both positive and negative relatedness

Daniel B. Krupp, Lisa M. DeBruine, Benedict C. Jones & Martin L. Lalumière
The evolution of spite entails actors imposing costs on ‘negative’ relatives: those who are less likely than chance to share the actor’s alleles and therefore more likely to bear rival alleles. Yet, despite a considerable body of research confirming that organisms can recognise positive relatives, little research has shown that organisms can recognise negative relatives. Here, we extend previous work on human phenotype matching by introducing a cue to negative relatedness: negative self-resembling faces, which...

Data from: Population genetic structure and its implications for adaptive variation in memory and the hippocampus on a continental scale in food-caching black-capped chickadees

Vladimir V. Pravosudov, , Matthew L. Forister, Lara D. LaDage, Theresa M. Burg, Michael J. Braun & Brian S. Davidson
Food-caching birds rely on stored food to survive the winter and spatial memory has been shown to be critical in successful cache recovery. Both spatial memory and the hippocampus, an area of the brain involved in spatial memory, exhibit significant geographic variation linked to climate-based environmental harshness and the potential reliance on food caches for survival. Such geographic variation has been suggested to have a heritable basis associated with differential selection. Here, we ask whether...
