The Physiological Society of Japan has traditionally focused on human biology, but insights from non-mammalian organisms such as insects and marine animals are broadening our view of physiological diversity and universality. These organisms differ from mammals not only in form but also in organ functions, physiological role allocation, and the structure and regulation of functional molecules. For example, in wingbeat sound production, as well as in cold tolerance, temperature sensing, and chemosensory functions like olfaction and gustation, insects exhibit distinct modes of sensory processing. Studying these mechanisms not only enhances our understanding of biological functions absent in humans, but also reveals hidden functions within human molecular systems. This symposium, under the theme “Knowing Insects to Understand Humans," presents findings from non-model organisms to explore new applications in human physiology. By learning from biological diversity, we aim to advance physiological science and contribute to disease understanding and therapeutic innovation.
