Curiosity is a wonder of the human mind. It goes to the heart of modernity, as a driving force for learning, novel insights, and innovation, both for individuals and communities. In societies dependent on science and development, finding out what promotes or hampers curiosity and wonder in school curricula and science education is accordingly essential. In this conceptual article, I suggest a framework for curiosity-based science education and I explore options for its wellbeing and development during preschool, preadolescence, and adolescence. (...) In preschool, curiosity and wonder are triggered by perceptive beauty rather than by facts, and a method emphasizing maximism as a complementary factor in preschool science education is proposed. In prepuberty, curiosity is encouraged by exploring the diversity of the world. Facts and clear-cut knowledge constitute a firm foundation for scientific thinking. In high school, curiosity is ignited by means of a better balance between models and phenomenology. Criticism has arisen over the one-sided use of models in high school science education, which limits scientific thinking to frameworks defined by the actual model. Possible solutions to maintain students’ curiosity and ideas to improve the balance between phenomenology and models are discussed. (shrink)

Adaptation by means of natural selection depends on the ability of populations to maintain variation in heritable traits. According to the Modern Synthesis this variation is sustained by mutations and genetic drift. Epigenetics, evodevo, niche construction and cultural factors have more recently been shown to contribute to heritable variation, however, leading an increasing number of biologists to call for an extended view of speciation and evolution. An additional common feature across the animal kingdom is learning, defined as the ability to (...) change behavior according to novel experiences or skills. Learning constitutes an additional source for phenotypic variation, and change in behavior may induce long lasting shifts in fitness, and hence favor evolutionary novelties. Based on published studies, I demonstrate how learning about food, mate choice and habitats has contributed substantially to speciation in the canonical story of Darwin’s finches on the Galapagos Islands. Learning cannot be reduced to genetics, because it demands decisions, which requires a subject. Evolutionary novelties may hence emerge both from shifts in allelic frequencies and from shifts in learned, subject driven behavior. The existence of two principally different sources of variation also prevents the Modern Synthesis from self-referring explanations. (shrink)
