How fast can evolution take place? In just a few years, according to a new study on guppies. Researchers found that guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation environment.
