Fitzpatrick’s lab houses 3000 aquariums containing small fish such as halfbeaks and guppies. The experiments carried out here include studying the mating behavior and sperm of the fish.
The impact of evolution on sexual selection
The urge among animals to reproduce manifests itself in extraordinary ways. John Fitzpatrick elaborates: “It leads evolution to develop hugely complicated behaviors, forms and structures. Everything is exaggerated in the most bizarre ways, since the evolutionary stakes are so high. We want to understand how and why certain sexual behaviors develop in some groups, but not in others.”
