Hypothesis

Is there a clear distinction between 'model organisms' and other species in developmental biology research?

Conclusion

There is no empirical basis for dividing species studied in developmental biology into 'model organisms' and others.

Supporting Evidence

  • The distribution of attention to different organisms follows a smooth power law.
  • Two genera, Mus and Drosophila, accounted for two fifths of papers published.
  • The study analyzed 4615 papers published in five different years.

Takeaway

Scientists study many different animals in developmental biology, but there's no special group of 'model organisms' that are more important than others.

Methodology

A quantitative analysis of organisms studied in developmental biology journals over five decades.

Potential Biases

Potential bias in the selection of journals and organisms studied.

Limitations

The study only includes papers from specific developmental biology journals and may not represent all research in the field.
