Evelyn Hutchinson, and their members include both graduate students and more experienced scientists. All of dem produce innovative research, wey include di opening of new subfields for embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group show say e be classic research school; Pickford's and Hutchinson's own no be.
