In an article aimed at high school students for the journalFrontiers for Young Mindswe introduce the evolutionary mystery posed by balanced lethal systems. We use crested newts as an example throughout. Please have a look here.

I am a biologist interested in the interaction among closely species, both ecologically and genetically, during the course of their evolution. In my studies I'm employing the newt genus Triturus.
