1 July is 150 years since Darwin published "The Origin of Species" Next February is his 200th birthday (Abe Lincoln's also). Party time!
"The reason the “Origin” was so powerful, compelling and persuasive, the reason Darwin succeeded while his predecessors failed, is that in it he does not just describe how evolution by natural selection works. He presents an enormous body of evidence culled from every field of biology then known. He discusses subjects as diverse as pigeon breeding in Ancient Egypt, the rudimentary eyes of cave fish, the nest-building instincts of honeybees, the evolving size of gooseberries (they’ve been getting bigger), wingless beetles on the island of Madeira and algae in New Zealand. One moment, he’s considering fossil animals like brachiopods (which had hinged shells like clams, but with a different axis of symmetry); the next, he’s discussing the accessibility of nectar in clover flowers to different species of bee.
