What Makes a Good Model System?
Model biological system philosophy:
We are unlikely to ever know everything about every organism.
Therefore, we should agree on some convenient organism(s) to study in great
depth, so that we can use the experience of the past (in that organism)
to build on in the future. This will lead to a body of knowledge in
that 'model system' that allows us to design appropriate studies of
non-model systems to answer important questions about their biology.
Historical statements of the philosophy:
Criteria for a model biological system:
- Is the organism used easy to rear?
- Is its rearing/operation size convenient?
- Is it inexpensive to operate?
- Does the organism used have short life cycle?
- Is the organism used geneticly manipulable?
- Does it promise economically important results?
- Dose it have an audience of interested people?
- Interactions between criteria.
