Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology
As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.
