Flowers need bees in order to reproduce, and bees need flowers to feed their colonies. Take away one, and the other would disappear too. It begs the question: When it comes to evolution, which came first, the bees or the flowers? Book recommendation: "A Sting in the Tale" by Dave Goulson, a great scientific and cultural history of bees http://amzn.to/1BcytS5 Special thanks to the Lady Bird Johnson Wildflower Center in Austin, TX for letting us hang out with their bees and flowers! https://www.wildflower.org/ More info/sources: http://www.scientificamerican.com/art... http://www.the-scientist.com/?article... http://www.bbc.com/earth/story/201410... http://science.nationalgeographic.com...
