In recent years, neuroscience has begun to limit itself to a few species given accessible research tools for genetics and other techniques are limited to only a few model species. Comparative studies of strategically chosen non-model species can complement model species research and yield more rigorous studies. Broadening the diversity of species used will also help ensure that biological diversity is well presented in neuroscience research. As genetic sequences and tools become available for many more species, we are poised to emerge from the bottleneck and once again exploit the rich biological diversity offered by comparative studies.
