About

I am an evolutionary biologist who explores questions of rapid evolution, sexual selection, and urban ecology. Most of my research is done on tropical freshwater fish, though I have also worked with birds and lizards. I love natural history museums. I also love reading, and as you might guess, particularly books on natural history — always accepting recommendations. I write a Substack, Sapere Aude, at https://eliasjohnson1.substack.com/
