Receptor Layer

In intraspecific incompatibility systems of the sporophytic type and in certain forms of interspecific incompatibility, the inhibition of the pollen or pollen tubes takes place on the stigma surface. The ‘recognition’ event involves proteins carried in the pollen wall, apparently in interaction with a proteinaceous receptor layer on the outer face of the walls of the stigma papillae. Stigma surface proteins have been detected by various techniques in species of more than 80 angiosperm families, and it seems that they are a characteristic feature of the group. The pellicle proteins, which can be stripped with SDS, have been partly characterized. An account is given of the nature and origin of the pellicle, and its likely function in mediating incompatibility responses discussed.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.

Abstract The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.
