Fishing for Clues
This Catalyst article describes how fish can help scientists to learn more about human biology. Understanding how human bodies work and what causes human disease is the key to future medical breakthroughs. Most discoveries in medical science are a result of experiments that cannot be performed on humans. Animal models enable scientists to obtain vital clues about the causes and progression of human diseases. There are ranges of model organisms to suit different topics, in this example zebrafish are used to model human disease.
