Can the science of Prosocial be a part of evolution education?

We provide a brief overview of Prosocial: Using Evolutionary Science to Build Productive, Equitable, and Collaborative Groups by Paul Atkins, David Sloan Wilson, and Steven Hayes. The book offers a range of promising content for evolution education, and yet also highlights core conceptual challenges in modern evolution science discourse that educators and researchers aiming to improve evolution education may find beneficial to strategically engage with as a scientific community. We discuss these challenges and opportunities with a view towards implications for evolution education research and practice

Educational potential of teaching evolution as an interdisciplinary science

Evolution education continues to struggle with a range of persistent challenges spanning aspects of conceptual understanding, acceptance, and perceived relevance of evolutionary theory by students in general education. This article argues that a gene-centered conceptualization of evolution may inherently limit the degree to which these challenges can be effectively addressed, and may even precisely contribute to and exacerbate these challenges. Against that background, we also argue that a trait-centered, generalized, and interdisciplinary conceptualization of evolution may hold significant learning potential for advancing progress in addressing some of these persistent challenges facing evolution education. We outline a number of testable hypotheses about the educational value of teaching evolutionary theory from this more generalized and interdisciplinary conception

Are humans a cooperative species? Challenges & opportunities for teaching the evolution of human prosociality

Evolutionary anthropologists commonly describe humans as a highly cooperative species, based on our evolved socio-cognitive capacities. However, students and the general public may not necessarily share this view about our species. At the same time, fostering our ability to cooperate is considered a key foundation for achieving sustainable development, and students’ understanding of the conditions that enable or hinder cooperation is therefore an important learning goal in sustainability education. In this article, we describe a small classroom activity that explored students’ and preservice biology teachers’ preconceptions about the human capacity to cooperate around shared resources in comparison to the capacity of our closest relative, the chimpanzee. Results indicate that students and teachers had limited knowledge about the evolved human capacity for cooperation around shared resources in small groups, most often viewing chimpanzees as more capable of cooperation and sustainable resource use. Based on the results of this classroom intervention, we highlight important learning opportunities for educators in biology on teaching human evolution and human behavior, particularly as related to current challenges of sustainable development

Cooperation as a causal factor in human evolution: a scientific clarification and analysis of German high school biology textbooks

Many evolutionary anthropologists view cooperation as core to the evolutionary success of our species. Concurrently, many sustainability scientists view cooperation as core to the future sustainable development of our species. When it comes to biology education, however, it is unclear how or if students are being engaged in these scientific perspectives. This article offers an overview of scientific perspectives regarding cooperation as a central causal factor in shaping human behaviour, cognition, and culture during human evolution. Against this background, we analysed 23 German high school biology textbooks with the aim to understand if and how cooperation is presented as a causal factor in human evolution and behaviour. Overall, the role of cooperation, especially the emotional and motivational aspects of cooperative behaviour, and the role of a cooperative social and cultural environment in shaping human traits, appears to be significantly deemphasized compared to the role of individual brain size and ‘intelligence’ in the evolution of our species. Furthermore, in sections on behavioural ecology, humans are hardly ever presented as an example of a highly cooperative species. Overall, textbooks show a diversity of strengths and weaknesses, from which we identify several learning opportunities in the appropriate integration of cooperation science within biology education

Modulation of hippocampal acetylcholine release - a potent central action of interleukin-2

The potential of the T-cell growth factor interleukin-2 (IL-2) to modulate the release of ACh from rat hippocampus was studied in vitro, as a means to investigate the possible functional significance of this cytokine in the CNS. Hippocampal slices were superfused with Krebs' buffer medium, and endogenous ACh released into the superfusate was measured using a radioenzymatic assay. Recombinant human IL-2 present during a stimulation with 25 mM KCl altered, in a concentration-dependent manner, the evoked transmitter release. At a concentration of 15 U/ml (< or = 1 nM), IL-2 inhibited ACh release by more than 50% of the control level (evoked ACh release from the untreated contralateral hemispheres). Inhibition was observed within 20 min of tissue exposure to IL-2 and lasted for up to 1 hr. The inhibitory effect of IL-2 was reversible since transient tissue exposure to IL-2 did not affect subsequent evoked ACh release. IL-2 at this concentration also significantly decreased evoked ACh in frontal cortical slices, but was ineffective in the parietal cortex and striatum, revealing that IL-2 selectively modulates the release of ACh from certain, but not all, cholinergic nerve terminals in the CNS. At very low concentrations (1.5 mU/ml, < or = 0.1 pM), IL-2 transiently increased hippocampal evoked ACh release, resulting in a biphasic dose-response profile with no significant effect observed at 0.015 mU/ml (< or = 1 fM). Other cytokines (IL-1 alpha, IL-3, IL-5, IL-6, interferon alpha), tested in hippocampal slice incubations, failed to modulate ACh release
