Non-mammalian animals can provide great insight into the principles of development and evolution, which in turn teaches us about human biology and disease. Such organisms include: classical genetic models such as fruitflies (Drosophila), fish used as models for the study of morphology and speciation (stickleback), pufferfish used as models of compact genomes, sea squirts used to assess the content of small chordate genomes and sea hare used as models for learning and memory in neurobiology (Aplysia).
The Broad Institute is involved in sequencing many such organisms, as listed below.
