From plants to songbirds to humans, hormones shape various aspects of organismal form and behavior over both contemporary and evolutionary time. Through a series of lectures and opportunities to interact with experts across the broad field of endocrinology, students will learn about: the components and function of the common endocrine pathways, the influence of hormones on organ and tissue development and homeostasis, the role hormones play in organisms’ abilities to respond to environmental stimuli and change, and the evolution of unique hormonal mechanisms. Exploration of hormones and behavior across a diversity of species will highlight the interconnectedness between various fields such as medicine, evolution, behavioral ecology, neuroscience, and developmental biology. By the end of the course, students will develop a deep understanding of the interplay between hormones and behavior, and will gain a solid foundation in the theories, concepts, and methods used in the field of endocrinology.
