Stickleback Evolution

Mr. Anderson discusses stickleback evolution, highlighting natural selection and microevolution. He explains historical studies and focuses on sticklebacks in Alaska's Loberg Lake. The lake was poisoned in 1982, leading to the introduction of marine sticklebacks. Over time, these evolved to resemble the original freshwater sticklebacks. The video covers data collection, analysis, and evidence of microevolution and speciation, showing evolution can occur rapidly.
