Humans causing rapid evolution in Baltic Sea fish

Human beings have affected virtually the entire environment of the earth, and the Baltic Sea has been impacted especially hard by toxic emissions and eutrophication in the last few decades. Animals that live in highly polluted environments can either die out locally or adapt and survive. In a new dissertation in natural science, Emma Lind, of Stockholm University and Södertörn University, shows that the three-spined stickleback fish have developed genetically in a short time in response to the environmental impact of humans.
