That's why the idea was so hard to accept when Darwin first came up with it: like the idea that the earth is round, not flat -- or that it goes round the sun, not the reverse -- it doesn't seem to fit with 'common' sense. That's still why some people find it difficult to fully grasp: the idea that a creator god simply divided life up into different species is much easier to accept than trying to get your head around changes that happened at snail's pace over hundreds of thousands, even tens of millions of years. To a mortal being who can only hope to live 100 years at best, that sort of speculation can soon start to make your head hurt. But things are different at smaller scales -- with insects, for example, where generations are measured in days, not decades. The reason why fruit flies have been so intensively studied by evolutionary scientists is that they have a li
