About 70 percent of the genes of the stickleback fish are the same as humans. In the video, scholars further explore the stickleback fish and its history, from being removed from Loberg Lake to their change and comeback. Over time, these fish adapted to their new environment via natural directional selection, over the course of only 20 years. This is the last video in a series of 18 evolution related videos.
